How is RD Maturity Calculated?
A Recurring Deposit (RD) is a savings product where you deposit a fixed amount every month for a fixed tenure at a fixed interest rate. The bank pays interest (usually compounded quarterly) and returns the total maturity amount at the end. RDs are ideal for salaried Indians who want disciplined monthly saving without market risk.
The RD Maturity Formula
- M — Maturity amount
- R — Monthly installment
- i — Quarterly interest rate (annual rate ÷ 4, in decimal)
- n — Total number of quarters (years × 4)
Note: Most Indian banks compound RD interest quarterly. Each monthly installment compounds for the remaining quarters until maturity.
A Worked Example
For a ₹5,000/month RD at 7% interest with quarterly compounding for 5 years, the maturity works out to approximately ₹3,58,800 — total invested ₹3 Lakh, interest earned ~₹58,800. The longer you stay invested, the more each early installment compounds.
What Affects Your RD Maturity?
- Monthly installment — Direct proportion. A ₹10,000/month RD earns 2× the interest of a ₹5,000/month RD at the same rate and tenure.
- Interest rate — Rates vary by bank, tenure, and customer category. Small finance banks pay ~1% more than scheduled commercial banks.
- Tenure — Longer tenure usually fetches higher rates. The sweet spot for most banks is 3–5 year RDs.
- Compounding frequency — Quarterly is the Indian default. Monthly compounding gives slightly higher returns.
- Senior citizen status — Depositors aged 60+ get an additional 0.25–0.75% (typically 0.5%) on most banks.
Tax on RD Interest
- RD interest is fully taxable at your income tax slab rate. There is no LTCG benefit (unlike mutual funds).
- TDS — Banks deduct 10% TDS if annual interest exceeds ₹40,000 (₹50,000 for senior citizens) per bank. PAN must be linked.
- Form 15G / 15H — If your total income is below the basic exemption limit, submit these forms to your bank annually to avoid TDS.
- Post-office RD — No TDS at source, but interest is still taxable as "income from other sources".
RD vs Other Investments
- RD vs FD — FD is a lump-sum deposit; RD is monthly installments. For the same total invested, FD gives slightly higher returns because the full amount compounds from day one.
- RD vs SIP — RD gives guaranteed but lower returns (6–8%); SIP returns are market-linked (11–14% expected for equity) but volatile. SIP wins for long-term wealth; RD wins for short-term certainty.
- RD vs PPF — PPF gives ~7.1% tax-free, RD gives 5.5–8% taxable. After tax (30% slab), RD effective rate drops to ~5%. PPF wins for tax efficiency over long horizons.
Tips for Higher RD Returns
- Compare rates across at least 5 banks — small finance banks (AU, Equitas, Ujjivan) often pay 1%+ more than HDFC/SBI.
- Don't miss installments — banks may close your RD or charge penalties (₹1–10 per ₹100 missed).
- If aged 60+, register for senior citizen rate before booking — it's not retroactive.
- Submit Form 15G/15H if you're below the tax threshold — avoids 10% TDS.
- Check the DICGC insurance limit — ₹5 Lakh per bank, so spread very large RDs across multiple banks.
- Consider a step-up RD — some banks allow yearly installment increases to match salary growth.
Frequently Asked Questions
RD vs FD — which earns more?
For the same total money invested, FD earns more. A ₹3.6L lumpsum FD for 3 years at 7% matures around ₹4.43L. The same ₹3.6L drip-fed as ₹10k/month RD for 3 years at 7% matures around ₹4.02L. The gap is the time-value of money — RD installments don't compound from day one. Pick RD when you don't have the lumpsum; pick FD when you do.
What if I miss an RD installment?
Banks charge a default fee (typically ₹1–₹10 per ₹100 of missed installment) plus pay only savings-account interest on the shortfall. Miss 4 consecutive installments and most banks reserve the right to close the RD prematurely with the early-withdrawal penalty. Set a standing instruction from your salary account to avoid it.
Is RD interest taxable?
Yes — fully taxable at your slab rate, same as FD. Banks deduct 10% TDS if total interest across all your deposits at that bank crosses ₹40,000/year (₹50,000 for seniors). PAN linkage is mandatory or TDS jumps to 20%. Submit Form 15G/15H annually if your total income is below the basic exemption limit.
Can I break the RD early?
Yes, but the bank applies a 0.5–1% penalty on the rate AND only pays you the rate that was applicable for the actual period held, not the booked rate. If you booked a 5-year RD at 7% and break it after 18 months, you'll get the 18-month rate (say 6.5%) minus 0.5% penalty — so ~6% net. Seniors lose the 0.5% bonus on early exit too.
RD vs SIP for someone just starting to save?
If you're new to saving and your priority is "don't lose money", start with RD — guaranteed 6.5–7%, no volatility, gets the habit going. If you can stomach paper losses and your horizon is 5+ years, SIP into a large-cap index fund — expected 11–13% long-term but with 20–30% drawdowns along the way. A common middle path: ₹3k/month RD for emergencies + ₹3k/month SIP for long-term wealth.
Is RD safe? What about bank failure?
RDs are insured by DICGC up to ₹5 Lakh per depositor per bank (principal + interest combined). For very large balances, spread across multiple banks. Scheduled commercial banks and licensed small finance banks are both covered.
What is the minimum RD installment?
Public banks (SBI, PNB) accept ₹100/month. Private banks (HDFC, ICICI) typically want ₹500–1,000/month. Post-office RD starts at ₹10/month — the lowest in India. Small finance banks usually start at ₹500–1,000 but pay 1%+ more.
Should I choose quarterly or annual compounding?
Quarterly. It's the Indian default and pays slightly more — a 5-year RD of ₹5,000/month at 7% gives ~₹3.59L quarterly vs ~₹3.57L annual. Don't pick annual unless your bank doesn't offer the alternative.
