Recurring Deposits Calculator
Free RD Calculator — Calculate Recurring Deposit Maturity Amount Instantly
Saving a fixed amount every month is one of the most reliable financial habits there is — but very few people actually know what that habit is worth at the end of a tenure. They deposit consistently, trust the bank’s stated rate, and collect whatever arrives at maturity. Bluxe’s free RD calculator puts that number in front of you before you commit. Enter your monthly deposit, annual interest rate, and tenure, and you’ll see your total invested amount, interest earned, and maturity value in seconds. For anyone planning a short-to-medium-term savings goal, knowing how to calculate recurring deposit returns accurately is the difference between guessing and planning.
What Is a Recurring Deposit?
A recurring deposit is a savings product offered by banks and post offices where you commit to depositing a fixed sum every month for a predetermined period. At the end of the tenure, you receive the entire accumulated amount along with interest — in one lump sum. Unlike a fixed deposit where the full principal is placed upfront, an RD builds the corpus gradually through monthly contributions.
What most people don’t realise is that RDs don’t use simple interest. Each monthly instalment is treated as a mini fixed deposit for its remaining tenure, and interest compounds quarterly on each of those instalments individually. The total maturity amount is the sum of all those individually compounded instalments — which is why the formula is slightly more involved than it first appears, and why eyeballing the return rarely gives you an accurate figure.
How Does This Calculator Work?
Because each monthly instalment earns interest for a different duration, the RD maturity formula sums the compound growth of every individual deposit.
The Formula
For each instalment:
A = P × (1 + r/n)^(n × t)
Total Maturity Amount = Sum of A for all instalments
Where:
- P = Monthly deposit amount
- r = Annual interest rate as a decimal (6% = 0.06)
- n = Compounding frequency per year (typically 4 for quarterly)
- t = Remaining time in years for each instalment
Interest Earned
Interest = Maturity Amount − (P × Total Months)
Why Quarterly Compounding Matters
Most Indian banks and the Post Office RD scheme compound interest quarterly. That means every three months, the interest credited to each instalment gets folded into its base. The first instalment — deposited at month one — compounds for the full tenure. The last instalment compounds for just one month. The net result sits somewhere between those two extremes, weighted by all the months in between.
Worked Example
Monthly deposit: ₹5,000 | Rate: 7% per year | Tenure: 3 years (36 months) | Quarterly compounding
Total invested = ₹5,000 × 36 = ₹1,80,000
Using the instalment-wise compounding formula across all 36 deposits:
Approximate maturity amount ≈ ₹2,01,400
Interest earned ≈ ₹21,400
That ₹21,400 is pure return above what you put in — earned without any active management, market exposure, or lock-in beyond the agreed tenure.
RD Maturity Reference Table
| Monthly Deposit | Annual Rate | Tenure | Total Invested | Approx. Interest | Maturity Amount |
|---|---|---|---|---|---|
| ₹1,000 | 6% | 1 year | ₹12,000 | ₹390 | ₹12,390 |
| ₹3,000 | 6.5% | 2 years | ₹72,000 | ₹4,820 | ₹76,820 |
| ₹5,000 | 7% | 3 years | ₹1,80,000 | ₹21,400 | ₹2,01,400 |
| ₹10,000 | 7.5% | 5 years | ₹6,00,000 | ₹1,02,750 | ₹7,02,750 |
| ₹2,000 | 6% | 10 years | ₹2,40,000 | ₹1,06,300 | ₹3,46,300 |
Notice the last row: ₹2,000 per month over 10 years generates more than ₹1 lakh in interest — on a product that carries zero market risk.
How to Use the Calculator on Bluxe
- Open the free RD calculator on Bluxe — no sign-up, no login, nothing to install.
- Enter your monthly deposit amount — the fixed sum you plan to contribute each month throughout the tenure.
- Input the annual interest rate offered by your bank or post office; check your RD account terms if unsure, as rates vary by institution and tenure.
- Set the tenure in years; if your bank quotes tenure in months, divide by 12 before entering.
- Click Calculate — your total invested amount, interest earned, and final maturity value appear instantly.
Practical tip: run the calculator with two or three different monthly deposit amounts to find the contribution level that hits your savings target without straining your monthly budget. The maturity amount scales linearly with the deposit, so doubling the monthly amount doubles the return.
Understanding Your Results
Three numbers appear: total invested, interest earned, and maturity amount. The most useful figure depends on your purpose. If you’re checking whether an RD fits a savings goal — say, accumulating ₹2 lakh for a planned expense — compare the maturity amount directly to your target. If you’re comparing an RD against another product like a debt fund or a fixed deposit, focus on the interest earned as a percentage of total invested. That’s your effective return, and it’s the only fair basis for comparison.
RD Return Interpretation Guide
| Interest as % of Total Invested | What It Reflects | Typical Scenario |
|---|---|---|
| Below 5% | Short tenure or low rate | 6–12 month RDs at 5–5.5% |
| 5% – 12% | Standard short-to-mid term | 1–3 year RDs at 6–7% |
| 12% – 25% | Medium tenure, decent rate | 3–5 year RDs at 7–7.5% |
| Above 25% | Longer tenure compounding | 7–10 year RDs at 6.5%+ |
These percentages reflect interest as a share of total principal invested — not annualised return. For annualised comparison with other products, divide the interest percentage by the number of years.
Why This Matters
Recurring deposits have quietly become one of the most widely used savings tools among salaried households — not because they offer the highest returns, but because the forced monthly commitment removes the temptation to spend what would otherwise sit in a current account. The discipline built into the product is part of what makes it effective, and that’s something a percentage figure alone doesn’t capture.
There’s also a less obvious advantage worth noting: RD interest rates at most public sector banks and the Post Office are revised periodically, but your rate is locked at the time of opening. If rates drop mid-tenure, your return is unaffected. That rate certainty makes RDs particularly useful when markets are volatile and fixed income rates are expected to fall — which is precisely when many cautious savers reach for them.
Practical Tips
Match your tenure to a specific goal RDs work best when the maturity date aligns with a planned expense — a vacation, a vehicle down payment, or an annual insurance premium. Closing an RD prematurely typically attracts a penalty of 0.5% to 1% on the applicable rate, which can meaningfully reduce your return on shorter tenures.
Compare post-office and bank RD rates before opening Post Office RD rates are set by the government and revised quarterly. They’re often competitive with — and sometimes higher than — private sector bank rates for equivalent tenures. Running both scenarios through the calculator before committing takes under a minute and can add up to a few thousand rupees over a 3 to 5-year tenure.
Factor in TDS on interest above ₹40,000 Banks deduct Tax Deducted at Source (TDS) at 10% on RD interest if your total interest income across accounts exceeds ₹40,000 in a financial year (₹50,000 for senior citizens). The calculator shows gross interest — your net receipt may be lower depending on your tax bracket and PAN submission status.
Use multiple shorter RDs instead of one long one Opening two or three RDs with staggered maturity dates — say, one for 1 year, one for 2 years, one for 3 years — gives you liquidity at intervals without breaking a single long-tenure account. This laddering approach is standard practice among experienced savers and costs nothing extra to set up.
Who Should Use This Calculator?
Anyone building savings through regular monthly contributions rather than a single lump-sum investment will find this tool directly applicable:
- Salaried individuals who set aside a fixed amount each month and want to know what that habit produces by a specific date
- Students or young earners starting their first savings habit who want to see projected returns before choosing between an RD and a savings account
- Parents planning a medium-term education or event fund where monthly contributions are more feasible than a one-time deposit
- Retirees or conservative investors who want guaranteed, predictable returns without any exposure to equity markets
- Anyone comparing an RD against a SIP or recurring mutual fund contribution and needing the RD side of that comparison calculated accurately
If you found this helpful, you might also want to try Bluxe’s [Fixed Deposit Calculator] to compare what a lump-sum deposit at the same rate and tenure would return.
A Note Before You Go
The figures this calculator produces are based on standard quarterly compounding and the inputs you provide. Actual maturity amounts may vary slightly depending on your bank’s specific compounding method, applicable TDS deductions, or penalties for premature withdrawal. Treat these results as an accurate planning guide — and confirm the final terms directly with your bank or post office before opening an account.
