A = P(1 + r/n)^(nt)
In the standard formula, P is principal, r is annual rate, n is compounding periods per year, t is years, and A is the final amount.
Capital Growth Simulator
Compound Calculator | Capital Growth Simulator
Estimate how capital may grow from your starting amount, return rate, and number of compounding periods.
Compound Inputs
You can treat the capital value as any unit, such as dollars, won, coins, or points.
Compound Results
These results are mathematical estimates from your inputs, not guaranteed returns.
Capital Growth Chart
The chart shows each step from your starting capital to the final result.

Compound growth guide
Review the formula, path, and assumptions behind the projection
This calculator is a transparent compound-growth model. It helps you compare repeated compounding with a simple-growth path, but it does not include real-world account frictions unless you adjust the inputs yourself.
Period-based model
The page applies your return rate once per period: final amount = starting capital x (1 + period return)^period count.
Match the period
If your return rate is monthly, use monthly periods. If it is annual, use annual periods or convert the rate before entering it.
1,000 at 5% for 10 periods
The compound path applies 5% to the updated amount at every step. The simple comparison applies 5% to the original 1,000 each time.
Chart and table
The chart shows the curve. The table shows each period's starting capital, profit, total capital, and cumulative return.
Not a market forecast
Taxes, fees, inflation, deposits, withdrawals, changing returns, and trading costs are not included unless you approximate them manually.
Responsible use: Treat the result as a mathematical scenario. It is not financial advice and cannot predict investment returns.
