Post Office PPF Calculator — India Post PPF Maturity — FY 2026-27

Post Office PPF — what is unique about India Post accounts

The maturity math is identical to every bank-held PPF — the Government of India sets one rate for all PPF accounts nationwide (currently 7.1% p.a. for the Apr–Jun 2026 quarter). What differs between a Post Office PPF and a bank PPF is the operational workflow, not the return. India Post runs roughly 1.5 crore PPF accounts, making it the second-largest custodian after SBI.

• Account opening: walk into any departmental post office, fill Form A, submit PAN + Aadhaar + passport-size photo + initial deposit (minimum ₹500, maximum ₹1.5 lakh). No net-banking opening flow yet for the Post Office variant as of April 2026 — branch-visit still required for new accounts.
• Subsequent deposits: cash, cheque, or online via India Post’s IPPB (India Post Payments Bank) mobile app. IPPB-linked PPF accounts get real-time deposit crediting identical to bank PPF.
• Passbook: traditional paper passbook at departmental post offices; e-passbook rolled out in phases from 2024. Download from the indiapost.gov.in customer portal after IPPB linkage.
• Nomination: Form E; up to 2 nominees supported with percentage allocation.
• Transfer to a bank: Form G to transfer the account from post office to an authorised bank; interest continues uninterrupted. Useful if you move to a city where your preferred post office is inconvenient.

Current Post Office PPF interest rate (Apr–Jun 2026 quarter)

7.1% p.a., compounded annually, credited on 31 March each year based on the lowest balance between the 5th and end of each month. Identical to the rate at SBI PPF, HDFC PPF, and every other authorised PPF custodian. Notified by the Department of Economic Affairs (DEA), Ministry of Finance — the rate has been held at 7.1% for eleven consecutive quarters. See our PPF Interest Calculator for a year-by-year breakdown of the interest component vs principal.

Premature closure + partial withdrawal at a Post Office PPF

Partial withdrawal is allowed once per financial year from the start of the 7th year. Maximum withdrawal = lower of (50% of balance at end of 4th preceding year) or (50% of balance at end of immediately preceding year). At a Post Office branch, withdrawals need Form C along with the passbook.

Full premature closure is allowed only from the start of the 6th year and only for three reasons: (1) life-threatening medical treatment of self / spouse / dependent children / parents with supporting hospital records, (2) higher education of self or minor child with admission letter, or (3) change of residency status to NRI. Closure invokes a 1% lower effective interest rate on all past years — the account is re-rated at 6.1% instead of 7.1% for compound calculations, with the difference refunded back to the post office.

Post Office PPF vs bank PPF — does it matter?

The interest rate is identical. The tax treatment (EEE under Section 10(11)) is identical. The Section 80C deduction eligibility is identical. The 15-year base tenure + 5-year extension blocks are identical. Differences are purely operational:

Choose Post Office PPF if your home branch is closer than a bank branch, or if you want the multi-nominee + rural-accessibility advantages. Choose bank PPF for the online convenience. Interest and maturity are identical in either case.
