SBI PPF Calculator — Public Provident Fund Maturity — FY 2026-27

SBI PPF calculator — monthly deposit vs annual lumpsum

SBI holds roughly 3.5 crore PPF accounts, the largest single pool in the country. PPF interest is uniform across all custodians (currently 7.1% p.a., Apr–Jun 2026 quarter) — what differs between SBI, HDFC, ICICI, and Post Office is the account-management experience, not the return. This calculator covers both deposit rhythms most SBI PPF holders use:

• Monthly ₹12,500 standing instruction via SBI YONO or SBI Internet Banking — auto-debit on a fixed date each month. Over 12 months = ₹1,50,000 (the annual 80C cap).
• Annual ₹1,50,000 lumpsum deposited before 5 April each year. This maximises interest because every rupee earns a full 12 months of compounding in the first year.

Both hit the same annual cap, but the annual-lumpsum route earns materially more over a 15-year term because PPF interest is calculated on the minimum balance between the 5th and last day of each month. Our worked example below quantifies the difference.

Monthly vs annual — 15-year maturity comparison

The ~₹1.2 lakh gap is real but not huge as a percentage (~2.97% of maturity). For most savers the monthly SI rhythm is more practical because it spreads the cash-flow impact. Choose annual if you have a March bonus you can deploy before 5 April; choose monthly otherwise.

SBI PPF monthly deposit — how to set it up

Three routes to a monthly PPF deposit at SBI. All three hit the same ₹12,500 monthly contribution:

1. SBI YONO app: Investments → PPF → Add Standing Instruction → ₹12,500, date 1st–5th, source SBI savings account. No branch visit.
2. SBI Internet Banking: e-Services → Standing Instruction → Create New → PPF account as beneficiary → ₹12,500 frequency monthly.
3. Branch form: Form for SI + PPF passbook; the branch enters it into CBS, takes 3 working days to activate.

Keep a ₹1,500 cushion in the source savings account on the SI date. SBI retries a failed SI once the next business day; if that also fails, the deposit is skipped and you need to top up manually before year-end to stay on track for the ₹1.5 L cap.

SBI PPF — partial withdrawal + loan features

• Partial withdrawal: allowed once per FY from year 7 onwards. Form C via SBI Internet Banking. Maximum: lower of 50% of 4th-preceding-year balance or 50% of preceding-year balance.
• Loan against PPF: year 3 to year 6. Up to 25% of 2nd-preceding-year balance. Interest rate PPF rate + 1% (so 8.1% at current rates). Repayable in ≤36 months. If unpaid, interest rises to PPF rate + 6% on the unpaid portion.
• Premature closure: from year 6, only for life-threatening medical, higher-education, or residency-status-change reasons. Account re-rated at 6.1% (1 percentage point lower) for all past years.

SBI PPF vs SBI Tax-saver FD vs SBI ELSS — 80C allocation

All three qualify for the ₹1.5 L Section 80C deduction. Return profile, lock-in, and tax treatment differ:

The typical sound allocation: split the ₹1.5 L 80C cap roughly 60:40 between PPF + ELSS. PPF gives the tax-free sovereign bedrock; ELSS captures equity upside with the shortest lock-in among 80C options. Tax-saver FD only makes sense if you specifically need a 5-year FD horizon and want the 80C benefit.
