The Basics
What is an RD Calculator and Why Do You Need One?
A recurring deposit calculator 2026 is a free online tool that computes the exact maturity amount, total interest earned, and net amount after TDS for a Recurring Deposit — based on your monthly installment, interest rate, and chosen tenure. Unlike a simple multiplier, a proper rd calculator online applies quarterly compounding as per the standard RBI formula for RDs, giving you accurate results that match what your bank will show at maturity.
The reason you need an rd interest calculator rather than doing it mentally is straightforward: RD interest calculation is more complex than FD. While an FD compounds a single principal, an RD involves a fresh deposit every month — each instalment earning compound interest for a different number of quarters. For a 12-month RD, your first instalment compounds for 4 quarters, your second for ~3.67 quarters, your last instalment compounds for just 1 quarter. The cumulative effect cannot be easily estimated in your head.
Our rd maturity calculator handles all of this accurately — whether you need a rd calculator for 1 year, 3 years, or the standard post office rd calculator 2026 5-year plan. It also computes TDS and shows a complete quarter-by-quarter growth table.
Quick Fact: A ₹5,000/month RD at 7% for 1 year yields approximately ₹62,230 — interest of ₹2,230 on a total investment of ₹60,000. Use our free monthly rd calculator to see exact results for any amount and tenure.
