Rules for PPF Scheme 2019, as amended. Last verified: 21 Sept 2026. Source: Public Provident Fund Scheme, 2019 (G.S.R. 915(E) dated 12 December 2019), amended by G.S.R. 290(E) dated 5 May 2020; National Savings Institute.

How this is calculated

PPF interest is not a generic SIP. Under the Scheme, interest is calculated each month on the lowest balance between the close of the 5th and the end of the month, and credited at year-end.

Yearly deposits are assumed to be made on or before the 5th of April, so they earn interest for all twelve months of that financial year. Interest is credited at the end of each financial year.

The notified rate can change every quarter. This estimate holds the current versioned rate constant for the whole term.

Questions

Is the PPF rate guaranteed for 15 years?

No. The government notifies small-savings rates every quarter. This calculator uses the current versioned rate and says so. Future years may differ.
