Building wealth is not only about how much money you earn. What you do with the money after it reaches your bank account can be just as important. Someone earning a high income but spending nearly everything they make may struggle to accumulate long-term wealth, while someone earning less but consistently saving and investing a meaningful percentage of their income can steadily build financial security over time. This raises an important question for anyone trying to improve their financial future: How much of your income should you actually invest?
You may have heard rules suggesting that everyone should invest 10%, 15%, or 20% of their income. Those percentages can provide useful starting points, but there is no single investment rate that works for everyone. Your ideal percentage depends on your income, expenses, debt, age, retirement goals, current savings, business situation, and how aggressively you want to pursue financial independence. For business owners and self-employed professionals, the calculation can become even more important because income may fluctuate and there may not be an employer automatically contributing toward retirement.
The better approach is to understand what you're trying to accomplish, determine what your finances can realistically support, and create a consistent investment strategy that can grow as your income increases.
Is 10%, 15%, or 20% Enough?
A common guideline is to save approximately 15% of your income toward retirement, although the appropriate amount varies considerably from person to person. For someone who starts investing early and remains consistent for decades, a percentage around this range could potentially create a substantial retirement portfolio over time. Someone who begins later, wants to retire earlier, or has significantly higher retirement spending expectations may need to invest considerably more.
Rather than treating a particular percentage as a universal rule, think of it as a starting point. If you're currently investing nothing, moving immediately to 20% may feel overwhelming. Beginning with 5% and gradually increasing that amount can still represent meaningful progress. On the other hand, if you're already investing 15% and have additional disposable income, increasing your investment rate could significantly accelerate your long-term goals.
The most important factor is consistency. Investing a sustainable percentage month after month and year after year is generally more practical than attempting an extremely aggressive savings rate for several months and then abandoning the strategy because it became unsustainable.
Start by Understanding Where Your Money Goes
Before deciding how much you should invest, you need to understand where your income is currently going. Many people know approximately how much they earn but have surprisingly little understanding of how much they actually spend each month.
Start by looking at your after-tax income and separating your expenses into major categories. Housing, transportation, insurance, groceries, utilities, debt payments, entertainment, travel, subscriptions, and discretionary purchases can consume a significant portion of income. Once you understand your normal monthly spending, you can identify how much money is realistically available for saving and investing.
This exercise often reveals opportunities that are easy to overlook. You may discover several hundred dollars each month going toward expenses you barely use or value. Redirecting even a portion of that money toward investments can make a meaningful difference when compounded over many years.
The goal isn't necessarily to eliminate everything you enjoy. Wealth management should help you build the future you want without making your current life miserable. Instead, focus on spending intentionally and making sure your financial priorities receive funding before unnecessary expenses absorb your remaining income.
Build a Financial Foundation Before Investing Aggressively
Investing is important, but putting every available dollar into long-term investments before establishing a strong financial foundation can create unnecessary problems. Before aggressively increasing your investment rate, consider building an emergency reserve that can cover unexpected expenses.
Without readily available cash, something as ordinary as a vehicle repair, medical bill, temporary income loss, or major home expense could force you to use credit cards or sell investments at an inconvenient time. Maintaining an appropriate emergency fund gives your investment strategy room to work without requiring you to constantly withdraw money.
The appropriate emergency fund varies depending on your circumstances. Someone with an extremely stable salary and predictable expenses may require a different reserve than a self-employed business owner whose income fluctuates significantly throughout the year. Business owners may also need separate personal and business reserves because a slow month could affect both their company and household income.
Think of your emergency savings as the foundation supporting your investment portfolio. Once the foundation is strong, you may be more comfortable directing additional income toward long-term wealth building.
What About Debt?
Debt is another important consideration when deciding how much of your income to invest. Not all debt should necessarily be treated the same way.
High-interest consumer debt can make building wealth extremely difficult because interest charges may accumulate faster than the reasonable return you expect from your investments. In those circumstances, aggressively reducing high-interest debt while maintaining some level of retirement savings may make more sense than maximizing investments while allowing expensive debt to continue growing.
Lower-interest debt creates a more complicated decision. A mortgage, business loan, or other relatively low-interest obligation may not require the same aggressive repayment strategy as high-interest credit card debt. Some people prefer the certainty of eliminating debt, while others prioritize investing additional money for potential long-term growth.
There isn't always one mathematically perfect answer because your risk tolerance, cash flow, interest rates, taxes, and personal goals all matter. The important thing is to have an intentional strategy instead of simultaneously carrying expensive debt and increasing discretionary spending while wondering why your net worth isn't growing.
Investing 10% of Your Income
For someone beginning their wealth-building journey, investing 10% of income can be a meaningful target. It is large enough to establish a real investment habit without requiring the dramatic lifestyle adjustments that a much higher savings rate might require.
Suppose you earn $70,000 annually and invest 10%. That would represent approximately $7,000 invested each year before considering investment growth. Over decades, consistent contributions combined with compounding could potentially build substantial wealth.
More importantly, reaching 10% doesn't have to be your final destination. Once you've adjusted to living on the remaining income, you can gradually increase your percentage.
Investing 15% to 20% of Your Income
Investing approximately 15% to 20% of your income can put you in a stronger position to accumulate long-term wealth, particularly when you start relatively early.
At $100,000 of annual income, a 15% investment rate represents $15,000 per year, while 20% represents $20,000. Over 10 years, that's $150,000 to $200,000 in contributions alone before accounting for any potential investment growth.
As your income increases, maintaining the same percentage also automatically increases the dollar amount you invest. This is one of the advantages of thinking in percentages rather than fixed dollar amounts. If your income grows from $70,000 to $100,000, your investment contributions increase with it instead of allowing every additional dollar to disappear into lifestyle upgrades.
What If You Want to Invest 25% or More?
Some people choose to invest 25%, 30%, or even more of their income. This can significantly accelerate wealth accumulation, but higher investment rates usually require more intentional financial decisions.
High-income earners may find these percentages easier to achieve because their essential expenses represent a smaller percentage of total income. Someone earning $200,000 annually doesn't necessarily need to spend twice as much on housing, transportation, food, and entertainment as someone earning $100,000.
This creates an opportunity. Instead of allowing lifestyle expenses to increase at the same rate as income, high earners can redirect a large percentage of raises, bonuses, commissions, and business profits toward investments.
Higher savings rates can also be important for people pursuing early retirement. If you want the option to stop working decades before traditional retirement age, you generally have fewer working years to accumulate assets and more retirement years those assets may need to support.
Your Age Can Change How Much You Need to Invest
Time is one of the most valuable resources an investor has. Someone who begins investing in their 20s may have four decades or longer for contributions to potentially grow before traditional retirement age. Someone who begins seriously investing at 45 has significantly less time.
This doesn't mean someone starting later can't build substantial wealth. It means their required investment rate may need to be higher.
For younger investors, developing the habit of investing can be incredibly valuable. Even if you can't invest a large amount immediately, getting started gives you time to increase contributions as your career progresses.
For people approaching retirement, the focus may shift toward maximizing available retirement contributions, reducing unnecessary expenses, evaluating retirement income needs, and making sure their portfolio aligns with their risk tolerance and expected retirement timeline.
Business Owners Need a Different Approach
Determining how much to invest can be more complicated when you're self-employed. Unlike traditional employees, business owners may not receive the same paycheck every two weeks. Revenue can change significantly from month to month, making a fixed monthly investment amount difficult to maintain.
One solution is to invest based on percentages rather than fixed amounts. For example, you might establish a system where a certain percentage of the money you pay yourself is automatically directed toward long-term investments.
During strong months, you'll automatically invest more. During slower months, the dollar amount decreases while the habit remains intact.
Business owners also need to balance personal investing with reinvesting in their company. Putting money back into marketing, employees, equipment, technology, inventory, or expansion could potentially generate attractive returns, but putting every available dollar into the business creates concentration risk. Your company should ideally help build your wealth rather than represent your entire wealth.
Creating retirement assets and investments outside the business can help diversify your financial future.
Don't Let Your Business Become Your Retirement Plan
Many entrepreneurs assume they will eventually sell their company and use the proceeds to fund retirement. That strategy can work, but relying entirely on a future sale creates considerable uncertainty.
Your company may be extremely valuable today, but industries change, competition increases, technology evolves, and buyer demand can fluctuate. Even a successful business owner may discover that their company isn't worth what they expected when they're ready to retire.
Building retirement savings alongside your business creates another source of long-term financial security. Instead of relying on one major liquidity event decades from now, you're consistently transferring some of today's success into assets intended for your future.
Using a Solo 401(k) to Invest More for Retirement
For eligible self-employed individuals and business owners with no employees other than potentially a spouse, a Solo 401(k) can be a powerful retirement savings tool.
A Solo 401(k) is designed specifically for self-employed individuals and owner-only businesses. Because an eligible business owner can potentially contribute in both an employee and employer capacity, the plan may provide significantly more retirement-saving flexibility than certain individual retirement accounts, depending on compensation, business structure, age, and applicable IRS limits.
Traditional contributions may also provide current tax advantages depending on your circumstances, while Roth contributions, when available under the plan, provide a different tax treatment. Choosing between the two should be based on your individual tax situation and long-term strategy rather than simply choosing whichever option sounds more attractive.
For business owners trying to increase the percentage of income they invest, maximizing available tax-advantaged retirement accounts can be an important part of the strategy.
Investing Beyond Traditional Stocks and Bonds
Building a diversified portfolio doesn't necessarily mean all of your retirement savings must be invested in traditional publicly traded securities.
Depending on the retirement plan and applicable rules, certain self-directed retirement accounts may allow investments in assets such as real estate, private lending, certain precious metals, private businesses, and other alternative investments.
These investments come with their own risks and rules. Alternative investments may be less liquid, harder to value, and more complicated than publicly traded stocks or funds. Retirement accounts are also subject to prohibited transaction rules and other restrictions that investors need to understand before moving forward.
For investors who understand alternative assets, however, the ability to diversify beyond traditional markets can provide additional flexibility when building a long-term portfolio.
Increase Your Investment Rate Every Time Your Income Goes Up
One of the simplest ways to build wealth without feeling like you're constantly sacrificing is to increase your investment percentage whenever your income rises.
Suppose you're currently investing 10% of your income and receive a 10% raise. Instead of allowing your spending to increase by the full amount, consider directing part of that raise toward investments.
Your lifestyle can still improve while your savings rate increases.
This approach is especially effective for business owners, sales professionals, and people receiving bonuses or commissions. When you have an unusually strong month or year, automatically allocating a percentage of that additional income toward investments prevents lifestyle inflation from consuming all of your progress.
Over time, you may move from investing 5% to 10%, then 15%, 20%, and beyond without experiencing a dramatic reduction in your standard of living.
Lifestyle Inflation Can Quietly Destroy Your Investment Rate
One of the biggest obstacles to investing more isn't necessarily low income. It's lifestyle inflation.
As people earn more money, they often upgrade their homes, vehicles, vacations, restaurants, clothing, subscriptions, and other expenses. Eventually, someone earning $150,000 can feel just as financially constrained as they did when earning $60,000.
The difference is that they now have a much more expensive lifestyle to maintain.
There is nothing inherently wrong with enjoying the money you earn. The problem occurs when spending automatically increases every time income increases.
Consider establishing your investment percentage first and treating it like a required expense. If your goal is to invest 20%, move that money toward your investments before deciding what to do with the remaining 80%. This effectively turns investing from something you do with leftover money into a priority built into your financial system.
Calculate Your Investment Rate Based on Your Goals
Instead of asking only, "What percentage should I invest?" consider asking a more useful question: "How much do I need to invest to reach the future I want?"
Start with your desired retirement age and lifestyle. Estimate how much annual income you may need and evaluate your existing savings. From there, you can estimate how much you'll need to contribute regularly to have a reasonable chance of reaching your target.
Someone who wants a traditional retirement at 67 may have a very different required savings rate than someone trying to achieve financial independence at 45.
Your target should drive your investment percentage rather than an arbitrary rule you found online.
A Simple Investment Framework
For many people, a reasonable starting framework is to first establish sufficient cash reserves and address high-interest debt. From there, begin investing a sustainable percentage of your income toward retirement and other long-term goals.
If you're currently investing less than 10%, focus first on consistently moving toward that level rather than becoming discouraged by someone saving 30%.
If you're already around 10%, consider working toward 15%.
If you're comfortably investing 15% to 20%, determine whether increasing your rate would help you reach retirement or financial independence sooner.
For high earners and successful business owners with significant disposable income, investing 20% to 30% or more may be achievable without dramatically changing their lifestyle.
The goal isn't to compete with anyone else's savings rate. It's to continually improve your own financial position.
Consistency Matters More Than Perfection
It's easy to spend months trying to determine the perfect investment strategy. Meanwhile, the most important thing you could be doing is simply investing consistently.
Your ideal savings rate will probably change throughout your life. You may invest less when buying a home, raising children, starting a company, or navigating an unexpected expense. During higher-income years, you may be able to invest substantially more.
That's normal.
Building wealth isn't about hitting the same percentage every year. It's about creating a long-term habit of consistently turning a portion of your income into assets.
The Bottom Line: How Much Should You Invest?
There is no universal percentage of income that everyone should invest. For many people, 10% can be a strong starting point, while 15% to 20% may provide a more aggressive approach toward long-term retirement goals. People pursuing early financial independence or those with significant disposable income may choose to invest 25%, 30%, or even more.
What matters most is creating a sustainable investment rate, aligned with your goals, and capable of increasing as your financial situation improves.
If you're a business owner or self-employed professional, the opportunity can be even greater. Instead of relying entirely on an employer-sponsored retirement plan, you can take greater control over how you save, where you invest, and how you prepare for retirement.
For eligible self-employed individuals, a Solo 401(k) can be one tool for turning business income into long-term retirement wealth. With potentially higher contribution opportunities, Traditional and Roth options depending on the plan, and the potential for greater investment flexibility with a properly structured self-directed plan, it can provide entrepreneurs with another way to take control of their financial future.
Ultimately, building wealth doesn't begin when you reach a certain salary. It begins when you consistently keep and invest a portion of what you earn.
Earn. Save. Invest. Repeat.
The percentage may change over time, but the habit is what builds the foundation for long-term financial freedom.

Investment returns are not guaranteed, and retirement plan rules and contribution limits can change.
