Retirement when you're your own boss: the habits that keep your money growing while you cut.
Compounding is growth on top of growth, a second shift your money works while you sleep. See how it works, why starting early beats saving more, the five levers behind it (you control four), and the habits that keep it running until you put the clippers down.

How compounding works
The SEC puts it simply: compound interest is the interest you earn on interest. $100 at 5% becomes $105 after a year. In year two it earns on all $105, so it ends at $110.25. That extra quarter is small at first. Give it time and it takes over.
For context: the S&P 500 averaged about 10.5% a year since 1926 with dividends reinvested. 12% and 15% are above that long-run average. No return is guaranteed.
Divide 72 by the yearly growth rate to see about how many years it takes your money to double.
Investor.gov's example: at 9%, money doubles about every 8 years.
Lever 1 · Time
Barber A starts at 22, saves for 10 years, then stops. Barber B waits until 32, then saves every month until 67. Same amount a month, same growth. Guess who ends up with more, then move the sliders.
Balances compared at 67 (A stops saving at 32 but stays invested). Growth shown before inflation; 12% and 15% are above the S&P 500's long-run average of about 10.5%. Real markets jump around; these smooth lines are for learning.
Try it · The compounding machine
Compounding runs on time, how much you feed it, the return, what it costs and whether you leave it alone. You can't control the market. Pull the other four hard.
Growth shown before inflation, compounded monthly. Fees are taken out of the return each year. For context, the S&P 500 averaged about 10.5% a year since 1926 with dividends reinvested, about 7.3% after inflation (Official Data). Past returns don't predict future ones.
Lever 2 · Feed it every week
You don't get a paycheck, so "save 10% of your check" rarely sticks. A set amount from every cut does. Make the transfer automatic every Friday, and raise it when you raise your prices.
48 working weeks a year. Shown in today's dollars (after an Example 3% inflation) so you can picture what it buys. Your per-cut amount is assumed to rise with prices.
Lever 4 · Keep more of it
A fee comes out of your balance every year, so the money it takes never gets to grow. The SEC's example: $100,000 growing 4% a year for 20 years.
Every fund lists its expense ratio, the yearly fee. Look it up before you buy. In 2025 the average dollar in index stock mutual funds paid 0.05% a year, and in actively managed stock funds 0.64% (ICI, asset-weighted).
Set dividends to reinvest. Then every dividend buys more shares on its own, and those shares earn dividends too.
Growth shown before inflation, compounded monthly. Fund fees only; adviser fees would come on top.
Lever 5 · Don't break the chain
The two fastest ways to stop it: pulling out when the market drops, and cashing out early for something else. Both cut the chain right where it was about to grow.
Six of the 10 best days came within two weeks of the 10 worst days. Sell after a bad day and you can miss the bounce.

The 10% generally applies before age 59½, with some exceptions. Your own Roth IRA contributions (not the growth) can come out tax- and penalty-free. The "left alone" figure grows at an Example 9% a year and is before inflation and before any income tax when you withdraw it (qualified Roth withdrawals are tax-free).
Where it grows
Inside a retirement account, your growth isn't taxed every year, so more of it stays in to keep compounding. You don't need a boss to open one. Here's what fits a barber, with 2026 limits.
Anyone with earned income under the income limit. Qualified withdrawals come out tax-free. $8,600 if you're 50+.
About 20% of your profit after the deductible half of SE tax. Employees must get the same percentage.
No employees but a spouse. Up to $24,500 as the "employee" plus the "employer" share. Catch-ups at 50+.
At shops with 25 or fewer employees ($17,000 at larger ones). The whole team saves; you match up to 3% or put in 2% for each eligible employee.
Schedule C profit after expenses.
Booth renters paid on a 1099 don't count as your employees.
Opening the account is step one. The money inside still has to be invested, for example in a low-cost, diversified index fund. Cash sitting in the account barely grows.
Not recommendations or endorsements. Fees and features change, so check each site. Fund expenses and some trading costs can still apply.
Your retirement number
Pick the monthly income you'd want, in today's dollars. Social Security covers part of it. Your compounding covers the rest. This uses your per-cut savings from slide 5.
Most financial advisers say you'll need about 70 to 80% of your pre-retirement income.
Retired workers averaged about $2,071 a month in January 2026 (SSA estimate). Yours is figured from the earnings you report, so report your cash and tips. Get your own estimate at ssa.gov/myaccount.
The 4% figure is a long-standing rule of thumb for how much you can take out of a mixed portfolio in year one and raise with inflation. Morningstar's research for 2026 puts it at about 3.9% for a 30-year retirement. It's a starting point, not a promise.
