WORKED EXAMPLE
What Is $10,000 at 4% for 5 Years?
Calculate five years of monthly compounding and compare a nearby rate scenario.
Amounts are shown in USD. Changing currency relabels the same example values; it does not apply an exchange rate.
Assuming a constant 4% APR, monthly compounding, and end-of-month deposits.

- $12,209.97
- Total contributions
- $10,000.00
- Growth / interest

How this example is calculated
The APR is converted to a monthly rate, interest is credited, and then the scheduled contribution is added. Real accounts may use daily balances, changing rates, taxes, fees, or different deposit timing.
rₘ = APR ÷ 12Bₘ = Bₘ₋₁(1 + rₘ) + CAssumptions you can check.
