Compounding calculator
How a balance changes when the same percentage is applied again and again, with or without regular additions.

Final balance

After 12 periods at +1.00% per period.
- Starting balance
- 10,000.00
- Growth
- +1,268.25
This shows the arithmetic of compounding, not an expected trading return. Real returns vary from period to period and are often negative.
Period-by-period schedule (12 periods)

How it is calculated
Each period the balance grows, or shrinks, by the rate, and any contribution is then added. The next period’s rate applies to that new balance — which is what separates compounding from earning the same amount every period.
closing balance = opening balance × (1 + rate ÷ 100) + contribution
This illustrates arithmetic, not an expected trading return. Real returns vary from period to period and are often negative, and losses compound just as gains do: after a 50% loss, it takes a 100% gain to get back to where you started.
Worked example
- 1,000 at 10% per period: 1,000 × 1.10 = 1,100 after the first period.
- 1,100 × 1.10 = 1,210 after the second.
- Adding 100 at the end of each period instead gives 1,200, then 1,420.
