Uses the standard bank RD formula with quarterly compounding. Tenure is rounded to the nearest quarter (3-month multiple), matching how banks calendar RD maturity.
How this is calculated
M = R × [(1+i)ⁿ − 1] / (1 − (1+i)⁻¹ᐟ³), where R is the monthly deposit, i is the quarterly rate (annual rate ÷ 400), and n is the number of quarters in the tenure.

Frequently asked questions
How is RD interest calculated?
Each monthly deposit earns compound interest for the time remaining until maturity, compounded quarterly — so earlier deposits earn interest for longer than later ones. Banks use a specific formula to account for this, which this calculator implements.
What's the difference between an RD and a SIP?
Both involve regular monthly contributions, but an RD earns a fixed, guaranteed bank interest rate, while a SIP invests in market-linked mutual funds with variable, potentially higher long-term returns.
Why is my tenure rounded to the nearest 3 months?
Banks calculate RD maturity in quarters (3-month blocks) since interest compounds quarterly — a tenure of 13 months is treated the same as 12 for calculation purposes, which this calculator matches.
Is RD interest taxable?
Yes — like FD interest, RD interest is added to your taxable income and taxed at your slab rate, with TDS deducted by the bank if annual interest exceeds ₹40,000 (₹50,000 for senior citizens).
