Recurring Deposit (RD) Formulae
RD maturity is calculated using a compound-interest formula, where each monthly deposit earns interest over time.
The standard formula used by most RD calculators is:
M = R × [((1 + i)^n – 1) / (1 – (1 + i)^(-1/3))]
Where:
- R = Monthly deposit amount
- i = interest rate
- n = Deposit Duration
- M = Maturity value
Total Interest Earned = Maturity Amount – Total Amount Deposited
Total Amount Deposited = Monthly Instalment × Number of Months
Example: Monthly Compounding Effect in RD (₹5,000/month for 5 years @ 7%)
- Monthly deposit: ₹5,000
- Tenure: 5 years (60 months)
- Interest rate: 7% p.a. (compounded quarterly)
Total Invested = ₹3,00,000
Interest Earned = ₹58,000
Maturity Amount = ₹3,58,000
How is RD Interest Calculated?
RD interest is calculated using compound interest and is usually compounded quarterly (every 3 months). Each monthly deposit earns interest from the time it is invested, and interest is added to the principal every quarter, allowing future interest to be calculated on the growing balance.

Why Compounding Frequency Matters in RD?
Compounding frequency determines how often interest is compounded on your RD, directly affecting your total returns. Most RDs use quarterly compounding, which adds interest every 3 months, helping your savings grow faster. Higher compounding frequency increases the effective return and results in a higher maturity amount over time.
