What is the RD Calculator?
A Recurring Deposit lets you save a fixed amount every month into a bank deposit that earns FD-like rates. Each monthly deposit compounds for its own remaining tenure, so the first instalment earns interest for the full period while the last earns almost none. RDs enforce saving discipline with guaranteed outcomes.
This calculator is for new earners building their first savings habit, savers with short goals (a vacation, a gadget, an emergency fund), and conservative investors who want guaranteed returns without market risk. It compounds each deposit monthly and shows the year-wise build-up.
RDs suit short goals — typically 6 months to 10 years — at rates tracking FD rates (currently ~6–7.5%), and like FDs, interest is fully taxable at your slab. For tenures beyond 5 years, compare the same monthly amount in the SIP calculator: at 12% versus 6.8%, the difference over 10 years is roughly 40% more corpus from the SIP — with market risk attached.
RD maturity formula
M = Σₖ P × (1 + i)^(n−k+1)
| Symbol | Meaning |
|---|---|
| P | Monthly deposit |
| i | Monthly interest rate (annual ÷ 12) |
| n | Total months; deposit k compounds for n−k+1 months |
Worked example
₹5,000/month for 5 years at 6.8%: you deposit ₹3,00,000 in total and receive ≈ ₹3.55 lakh at maturity — interest of ≈ ₹55,000. The first deposit compounds for all 60 months; the last for just one.
| Item | Value |
|---|---|
| Monthly deposit | ₹5,000 |
| Total deposits (60) | ₹3,00,000 |
| Interest earned | ≈ ₹55,000 |
| Maturity value | ≈ ₹3.55 L |
Benefits of the RD Calculator
Guaranteed returns with forced monthly discipline
The fixed monthly contribution builds a saving habit that a lumpsum deposit cannot enforce.
Start with as little as ₹100–500/month
RDs are accessible from the first paycheck, with no large upfront commitment.
No market risk; DICGC insured up to ₹5 lakh
Like FDs, RDs carry sovereign-backed deposit insurance and zero volatility.
Predictable maturity value for short goals
You know the exact maturity amount on day one, useful for goals with a fixed deadline.
Available at every bank and post office
No special account or platform needed — open one wherever you already bank.
Limitations to keep in mind
Interest fully taxable at slab rate
RD interest gets no tax exemption; high earners lose a third of the return to tax.
Lower returns than market-linked options
Over 5+ years, equity SIPs have historically delivered meaningfully more, with volatility.
Penalties for missed instalments and early closure
Banks charge per missed month and penalise premature closure, reducing the guaranteed return.
Poor inflation-beating ability over long tenures
Post-tax, post-inflation RD returns are near zero — RDs preserve, they do not grow wealth.
Rigid contribution schedule
Unlike a SIP you cannot easily skip a month or change the amount mid-tenure without penalties.
Common mistakes to avoid
Using RDs for long-term goals
Beyond 5 years, post-tax RD returns trail equity SIPs by a wide margin.
Missing instalments
Banks levy penalties per missed month and repeated misses can close the account.
Ignoring tax on interest
RD interest has no TDS threshold advantage — it is fully taxable every year on accrual.
Locking the entire emergency fund
RDs penalise premature closure; keep one month’s deposit liquid.
Not comparing with debt funds
Debt funds offer similar returns with better liquidity and no missed-instalment penalty.
Expert tips for better results
Use RDs only for goals under 3 years
For longer horizons, equity or hybrid SIPs deliver more after tax and inflation.
Set the RD date just after salary credit
Timing the debit to payday ensures you never miss an instalment for cash-flow reasons.
Compare post-tax RD with debt funds
In the 30% bracket, a 6.8% RD is 4.8% post-tax — check whether a debt fund beats that after its tax.
Ladder RDs for liquidity
Stagger RD maturities so one matures every few months, creating a rolling liquidity cushion.
Consider post-office RD for sovereign backing
Post office RDs run 5-year tenures at government-set rates with quarterly compounding and full sovereign guarantee.
