SBI Compound Interest Calculator

Key India terms (used throughout this page)

Fixed Deposit (FD)

Lump-sum deposit, fixed tenure, fixed rate. SBI compounds quarterly. TDS at 10% above ₹40K/yr interest (₹50K for seniors).

Recurring Deposit (RD)

Fixed monthly deposit, FD-like rates, quarterly compounding. Useful for forced savings; interest fully taxable.

PPF

Public Provident Fund. Use the current notified rate, contribution limits, lock-in and tax rules; these terms should be verified before relying on a projection.

SIP (Systematic Investment Plan)

Fixed monthly investment into an equity or debt mutual fund. Returns are variable; model a documented range rather than a guaranteed rate.

SBI Fixed Deposit: use the stated convention

SBI Fixed Deposits can have different payout and compounding conventions. Enter the current rate, term and customer category from the product disclosure; taxes, premature withdrawal rules and senior-citizen benefits depend on the selected product.

SBI Recurring Deposit (RD): monthly contribution math

An SBI RD lets you deposit a fixed amount each month. Enter the current RD rate and term from SBI's disclosure; interest is generally taxable and tax-saver products have separate eligibility, lock-in and deduction rules.

PPF: the tax-free compound machine

PPF has a government-notified rate, contribution limits, a 15-year base lock-in and specific tax rules. Check the current notification and model the announced rate for the relevant quarter; do not assume it stays unchanged.

SBI savings account: simple math

SBI savings rates and compounding conventions are published by the bank and can change. Enter the current rate, compare liquidity and insurance, and keep emergency cash aligned with your access needs rather than a fixed product recommendation.

FD vs equity mutual fund SIP (long term)

Over a 20-year horizon, the comparison gets stark:

• SBI FD: enter the current disclosed rate and payout convention
• PPF: enter the notified rate and contribution limits for the relevant period
• Equity mutual-fund SIP: use a range of nominal or real scenarios; returns are not fixed

FDs are zero-volatility but inflation-vulnerable. Equity SIPs swing ±30% in any given year but historically beat FD by 4–6 percentage points over 10+ year periods in India.

Tax implications

SBI FD interest is fully taxable as per income slab. TDS of 10% kicks in when interest exceeds ₹40,000/year (₹50,000 for senior citizens). PPF interest is fully tax-free. ELSS mutual funds offer 80C deduction with 3-year lock-in — often the best tax-adjusted return option for the salaried.

How to use this calculator

For an SBI FD, select the compounding and payout convention in the disclosure, then enter the current rate and term. For an RD, enter the current rate, term and monthly deposit. For PPF, use the notified rate, limits and contribution schedule for the relevant period. Currency is pre-set to INR.

FAQ

What is the SBI FD compounding frequency?

Quarterly — SBI FDs compound 4 times per year, on each calendar quarter end.

How is PPF interest calculated?

PPF interest and crediting follow the government scheme rules and current notification. Check the official terms for the applicable period rather than assuming a fixed rate.

Is FD better than PPF?

For tenures over 15 years and any taxpayer in the 20%+ slab, PPF beats FD due to tax-free interest. For shorter horizons or non-taxable income, FD offers more flexibility (different tenures, premature withdrawal).
