Deposit Calculation
Formula and decision logic
Savings projections depend on the starting principal, regular contributions, annual rate, and compounding assumptions across the saving period.
Maturity amount = principal + total contributions + accumulated interest

- 2Enter the annual interest rate and term
- 3View the total interest earned and final balance
How to read the result
- Longer terms amplify the impact of interest, while higher monthly deposits usually have the biggest absolute effect.
- A realistic plan should compare maturity amount with total principal and total interest separately.
Common input mistakes
- Focusing only on the final balance without separating your own contributions from earned interest.
- Comparing plans with different durations as if the annual rate were the only difference.
