SBI RD Interest & Maturity Calculator
Estimate maturity amount for a State Bank of India recurring deposit using quarterly compounding logic.
What is an SBI RD account?
A recurring deposit (RD) allows you to invest a fixed amount every month and earn interest over a chosen tenure. It is useful for disciplined savings because your money grows steadily without needing a large lump sum at the start. SBI offers RD products with multiple tenures, and interest is generally compounded quarterly.
How this RD interest calculator works
This calculator estimates your maturity value based on:
- Monthly deposit amount
- Annual RD interest rate
- Tenure in months
- Optional senior citizen rate benefit
After calculation, you will see:
- Total amount invested (your monthly deposits)
- Estimated interest earned
- Estimated maturity value (principal + interest)
Formula used in this page
We use a commonly referenced recurring deposit maturity equation aligned with quarterly compounding:
M = P × [((1 + i)n − 1) / (1 − (1 + i)−1/3)]
- M = Maturity amount
- P = Monthly deposit
- i = Annual interest rate / 400
- n = Tenure in months / 3
Example: SBI RD maturity estimate
Suppose you deposit ₹5,000 per month for 5 years (60 months) at an annual rate of 6.80%. Your total invested amount will be ₹3,00,000. The calculator then estimates interest based on quarterly compounding and shows the projected maturity value.
This helps you compare plans quickly—like choosing between 36 months and 60 months—before opening an RD account.
Benefits of using an RD calculator before investing
- Better planning: You know how much corpus you may accumulate.
- Goal alignment: Match investment to goals like education, emergency funds, or travel.
- Tenure comparison: Understand how extending tenure changes returns.
- Rate sensitivity: Small rate changes can affect maturity over longer periods.
Things that affect your SBI RD returns
1) Interest rate at booking
RD return depends on the rate applicable when your deposit is opened. Always confirm the latest SBI RD rate for your chosen tenure.
2) Deposit discipline
Missing or delaying installments may lead to penalties and can impact final proceeds. Staying regular is key for maximizing the benefit of recurring deposits.
3) Tenure selection
Longer tenure usually means more compounding opportunities. However, select tenure based on your cash flow and financial goals.
4) Tax impact
Interest earned on RD is taxable as per your income tax slab. Depending on rules and thresholds, TDS may also apply.

Quick FAQ
Is this calculator only for SBI?
It is optimized for SBI-style RD estimation. You can still use it for other banks, but actual results depend on their exact compounding and policy rules.
Does this show guaranteed returns?
It shows an estimate based on entered inputs. Bank-calculated maturity at the time of account opening is the final reference.
Can I use years instead of months?
Yes. Just convert years into months (for example, 5 years = 60 months) and enter that value.
