Finance Calculator
How to use this calculator
Enter the yearly contribution and rate you want to model. Keep the contribution and horizon within the form’s modelled ranges, and check current account rules separately.
How the estimate is calculated
Assumes the full contribution is made at the start of each year and annual interest remains constant. Each year’s balance includes that year’s contribution before interest.
Assumptions and exclusions
Actual PPF interest depends on deposit timing and notified rates. The model does not implement monthly eligible-balance calculations, account eligibility or every extension rule. Defaults are illustrative, not verified current rates.
Official reference: Check the relevant government guidance. The calculator implements a simplified app model.
