What this calculator does
Estimate a savings balance with recurring deposits and flexible compounding.
Use it to turn Starting balance, Recurring deposit, Contribution frequency, Annual interest rate, and the other shown inputs into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this finance calculation.
Inputs and what they mean
- Starting balance
- — number value.
- Recurring deposit
- — number value.
- Contribution frequency
- — choice value.
- Annual interest rate
- — number value.
- Duration
- — number value.
- Compound frequency
- — choice value.
How to use it
- Enter the values for your estimate.
- Adjust the rate, duration, and optional scenario inputs.
- Review the totals, comparison, chart, and schedule where available.
Formula
Each period, the current balance earns rate ÷ compounding periods, then the recurring contribution is added at the end of that period.
Inputs used: Starting balance, Recurring deposit, Contribution frequency, Annual interest rate, Duration, Compound frequency.
Edge handling: Starting balance is required.; Starting balance cannot be negative.; Starting balance must be no more than 1000000000000.; Recurring deposit is required.; Recurring deposit cannot be negative..
Worked example
Ten-year growth estimate
- Start with Starting balance: 10000, Recurring deposit: 200, Contribution frequency: 12, Annual interest rate: 5, Duration: 10, Compound frequency: 12.
- Apply the method: Each period, the current balance earns rate ÷ compounding periods, then the recurring contribution is added at the end of that period.
- Start with $10,000 and add $200 monthly at an estimated 5% annual rate.
