Understanding ppf calculator
PPF projections are sensitive to when deposits become eligible for interest. This tool compares an ideal full-year eligible deposit with a deposit receiving no new interest that year. Actual account statements can differ when contributions arrive on multiple dates, interest rates change or withdrawals occur.
Formula and calculation method
For a start-of-year deposit: ending balance = (opening balance + eligible annual deposit) × (1+rate). For an end-of-year deposit: ending balance = opening balance × (1+rate) + deposit. Stop deposits after the entered contribution years.
India scheme projection with annual contributions and annual interest credit. The start timing assumes the deposit is eligible for all monthly interest calculations; actual PPF/SSY interest uses monthly eligible balances and deposit cut-off rules. Partial withdrawals, changing rates, contribution caps, eligibility and exact maturity dates are not assessed. Defaults are examples, not current scheme rates.
How to use ppf calculator
- Set Annual deposit. The example below uses 100000.
- Set Assumed annual scheme interest (%). The example below uses 7.
- Set Total projection years. The example below uses 15.
- Set Years making deposits. The example below uses 15.
- Set Annual deposit timing by choosing the option that matches your calculation.
- Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.

Factors affecting your result
India scheme projection with annual contributions and annual interest credit. The start timing assumes the deposit is eligible for all monthly interest calculations; actual PPF/SSY interest uses monthly eligible balances and deposit cut-off rules. Partial withdrawals, changing rates, contribution caps, eligibility and exact maturity dates are not assessed. Defaults are examples, not current scheme rates.
Changing annual deposit changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
Frequently asked questions
How does the ppf calculator work?
For a start-of-year deposit: ending balance = (opening balance + eligible annual deposit) × (1+rate). For an end-of-year deposit: ending balance = opening balance × (1+rate) + deposit. Stop deposits after the entered contribution years.
What inputs does PPF Calculator need?
Enter annual deposit, assumed annual scheme interest (%), total projection years, years making deposits, annual deposit timing. Read the unit labels; percentages are entered as ordinary percentages, not decimal fractions.
How should I interpret the ppf calculator result?
India scheme projection with annual contributions and annual interest credit. The start timing assumes the deposit is eligible for all monthly interest calculations; actual PPF/SSY interest uses monthly eligible balances and deposit cut-off rules. Partial withdrawals, changing rates, contribution caps, eligibility and exact maturity dates are not assessed. Defaults are examples, not current scheme rates.
