RD Calculator India – How to Use and What to Know
This RD calculator takes three inputs — monthly deposit amount, annual interest rate, and tenure in months — and shows total contribution, interest earned, and maturity value. It is useful for comparing RD rates across banks or post office before you open an account.
How Each Installment Earns Interest
Unlike a fixed deposit where all money is placed upfront, an RD builds up month by month. The first installment stays invested for the full tenure and earns the most interest; the last installment earns interest for only one month. This calculator aggregates the future value of each monthly contribution using the standard formula:
FV = P × [((1 + r)n − 1) / r] × (1 + r)
where P is the monthly deposit, r is the monthly interest rate (annual ÷ 12), and n is the number of installments. The result will be close to — but may not exactly match — your bank's internal calculation due to differences in day-count or compounding convention.
Compounding Convention for Bank and Post Office RDs
Bank RDs in India typically compound interest quarterly, meaning the effective per-month rate is derived from the quarterly equivalent of the annual rate. Post-office RDs follow separately notified rules. This calculator uses quarterly compounding as the default. If your product compounds differently, treat the output as a close planning estimate rather than an exact figure.
What Happens if You Miss Installments
Most Indian banks charge a penalty for missed RD installments. Accumulating missed installments can reduce your effective maturity amount and, in some products, trigger account dormancy. This calculator assumes regular, on-time deposits throughout the tenure. If you anticipate irregular payments, the actual maturity will be lower than shown.
Tax Treatment of RD Interest
RD interest is taxed as “Income from Other Sources” at your applicable slab rate — the same treatment as FD interest. Banks deduct TDS when your total interest income with them exceeds the applicable threshold. Unlike FDs, bank RDs generally do not qualify for a Section 80C deduction. Post-office RD interest is also fully taxable. This calculator shows pre-tax maturity; deduct tax on the interest portion to estimate your post-tax outcome.
RD Calculator India – FAQs
Does the maturity estimate match my bank's exact figure?
It will be very close but may differ by a small amount. Banks can use slightly different day-count conventions and internal rounding rules. Always confirm the final maturity figure directly with your bank before opening an RD.
What compounding frequency does this RD calculator use?
Quarterly compounding, as used by most Indian banks for RDs. Post-office RDs follow separately notified rules and may produce a slightly different outcome.
What happens if I miss one or more monthly installments?
Most banks charge a penalty for each missed installment. This calculator assumes all installments are paid on time. Actual maturity will be lower if installments are skipped, and the exact penalty structure depends on your bank's product terms.
Is the maturity amount shown pre-tax or post-tax?
Pre-tax. RD interest is taxable at your slab rate. Subtract the applicable tax from the interest component shown to estimate your post-tax return.
Does RD investment qualify for a Section 80C deduction?
Bank RDs generally do not qualify for Section 80C deduction. Only specific products like 5-year tax-saving FDs qualify. Check with your bank whether your RD scheme has any special tax-benefit provision.
Can I use this for post-office RD planning?
Yes, as a planning estimate. Enter the current notified post-office RD rate and your deposit amount. The result may differ slightly from the post office's official calculation due to different compounding conventions for that scheme.
