Assumptions

Assumes the full annual investment is made at the start of each PPF year — real PPF interest is computed monthly on the lowest balance between the 5th and last day of the month, so depositing early in April specifically can earn slightly more than this model assumes.
Uses the PPF interest rate for the Jul-Sep 2026 quarter (7.1% p.a.), which the Ministry of Finance reviews and can revise every quarter.
PPF interest earned and maturity proceeds are currently tax-exempt (EEE status) under prevailing rules.
