Calculate maturity amount for Recurring Deposits.
The Recurring Deposit (RD) Calculator is your essential tool for planning systematic monthly savings with guaranteed returns. A Recurring Deposit is a popular savings instrument offered by banks and post offices in India, allowing you to deposit a fixed amount every month and earn compound interest over a chosen tenure ranging from 6 months to 10 years. This makes it one of India's most popular wealth-building vehicles for salaried individuals and conservative investors alike.
RDs combine the strict discipline of regular monthly contributions with the ultimate capital protection of fixed deposits. Your principal investment is fully secure, protected by federal deposit insurance up to ₹5 lakh per depositor per bank under the DICGC (Deposit Insurance and Credit Guarantee Corporation). For savers looking to eliminate counterparty risk entirely, Post Office RDs carry a sovereign guarantee from the Government of India, making them a bulletproof destination for emergency funds or short-term milestones like vacations, education, or loan down payments.
In May 2026, fixed income yields remain highly competitive. While interest rates vary between 5.5% and 8.5% based on your choice of institution, tenure, and age bracket, this calculator instantly projects your exact total investment, total interest accrued, and final maturity values to optimize your wealth-building strategy.
M = Maturity amount (total payout)
P = Monthly deposit amount
r = Annual interest rate (expressed as a decimal, e.g., 7% = 0.07)
n = Compounding frequency per year (standardized at 4 for quarterly compounding)
t = Total tenure in years
Indian banking institutions utilize the RBI-standard quarterly compounding formula shown above. Because money is added incrementally rather than all at once, each monthly installment earns interest strictly for its remaining lifespan. Your very first deposit works the hardest, earning interest across the full tenure, while your final installment earns interest for just one month.
Indicative annual interest rates across major financial sectors as of May 2026:
| Bank Category | 1-Year Rate | 3-Year Rate | 5-Year Rate | Senior Citizen Premium |
|---|---|---|---|---|
| Public Sector Banks (SBI, PNB) | 6.0% - 6.5% | 6.25% - 6.75% | 6.0% - 6.5% | +0.50% |
| Private Banks (HDFC, ICICI, Kotak) | 6.5% - 7.25% | 7.0% - 7.25% | 6.75% - 7.0% | +0.50% |
| Small Finance Banks (Suryoday, AU, Unity) | 7.0% - 8.5% | 7.5% - 8.25% | 7.25% - 7.75% | +0.50% |
| Post Office Recurring Deposit | N/A | N/A | 6.7% Fixed | No senior citizen bonus |
• Market Leaders: Small Finance Banks continue to offer aggressive interest premiums to gather retail capital. Unity SFB leads up to 8.5%, Suryoday SFB scales between 8.0% and 8.25%, and AU SFB hovers around 7.75% to 8.0% for elite windows.
• Large Commercial Tiers: HDFC Bank and Kotak Mahindra offer steady ranges around 7.0% to 7.25%, ICICI rests between 7.0% and 7.10%, and SBI scales from 6.5% up to 7.0% for the general public (hitting 7.5% for seniors).
• The Post Office Footprint: India Post operates a mandatory 5-year lock-in structure at 6.7% p.a. while explicitly bypassing extra senior citizen tiers.
Just like standard Fixed Deposits, RD interest returns are fully taxable. Earnings are added to your gross yearly income and taxed matching your individual tax slab. This creates an intense tax drag for top-tier earners. For instance, an investor stuck in the 30% income tax bracket holding a 7.5% premium RD will find their true post-tax yield reduced to 5.25%. For long-term horizons up to ₹1.5 lakh per year, alternative avenues like the Public Provident Fund (PPF) at 7.1% tax-free often net higher final wealth.
Additionally, commercial banks are legally mandated to deduct a 10% Tax Deducted at Source (TDS) matching legal regulations whenever your aggregated cumulative interest across all accounts within a single bank climbs above ₹40,000 per year (or ₹50,000 if you are over 60). If your global total taxable income sits entirely below basic tax thresholds, you must proactively file Form 15G or Form 15H with your bank branches to prevent automatic deductions. Notably, Post Office RDs are completely exempt from automated TDS deductions, making them highly efficient for retail savers hovering near the tax boundaries.
Understanding where to deploy your excess monthly cashflow depends on your time horizon and volatility risk tolerances:
| Feature Metric | RD (Recurring Deposit) | FD (Fixed Deposit) | SIP (Mutual Funds) |
|---|---|---|---|
| Investment Style | Fixed monthly installments | One-time single lump sum | Flexible monthly allocation |
| Target Returns | 5.5% - 8.5% (Fully Guaranteed) | 6.0% - 9.0% (Fully Guaranteed) | 10% - 15% (Market-Linked Variable) |
| Risk Exposure | Zero (Capital fully protected) | Zero (Capital fully protected) | Moderate to Extremely High |
| Entry Thresholds | Low (₹100 - ₹500 / month) | Medium (₹1,000 - ₹10,000) | Low (₹500 / month) |
| Liquidity Rules | Premature penalty applied | Premature penalty applied | Highly flexible / Exit-load dependent |
| Strategic Alignment | Short-term targets (less than 3 years) | Lump sum preservation | Long-term compound wealth (7+ years) |
The Ideal Mixed Strategy: Use a Recurring Deposit first to lock in an untouchable 6-month living-expense emergency fund. Once that safe foundation is complete, redirect your excess cash surplus toward an equity SIP to systematically combat inflation over long horizons.
❌ Missing Installments: Skipping monthly deposit dates drops accounts into default status, triggering recurring transactional penalties and potentially forcing an early account closure. Keep your savings regular by setting up automated auto-debit triggers on your core savings accounts.
❌ Triggering Premature Early Terminations: Liquidating an active RD before maturity breaks the interest structure, incurring a 1% to 2% penalty rate drop. If near-term liquidity remains highly unpredictable, opening multiple smaller value RDs provides better transactional freedom than a singular giant account.
❌ Blindly Renewing without Re-checking Options: Interest rates change dynamically with central bank repo trends. Never rely on blind automatic extensions; spend a few moments checking shifting marketplace alternatives before locking in long tenures.
Sources & Methodology: Mathematical configurations rely strictly on standard quarterly compounding rules issued by the Reserve Bank of India (RBI). Reference pricing structures are tracked against published May 2026 baseline materials from SBI, HDFC Bank, India Post, and selected Small Finance Banks. Capital insurance coverage functions strictly under current DICGC statutory mandates. Always re-verify pricing directly with your primary banking vendor prior to signing final deposit contracts. Application data updated May 2026.
RD maturity uses quarterly compounding: M = P × [(1 + r/n)^(n×t) − 1] / [1 − (1 + r/n)^(−1/3)], where P = monthly deposit, r = annual rate as decimal, n = 4, t = years. Example: ₹5,000/month at 7% for 3 years = ₹2,00,550 maturity (₹1,80,000 principal + ₹20,550 interest). Each monthly installment earns interest only for its remaining tenure — the first deposit earns the most, the last earns just one month's interest.
Small Finance Banks lead: Unity SFB up to 8.5%, Suryoday SFB 8.0–8.25%, AU SFB 7.75–8.0%. Large banks: Kotak Mahindra 7.0–7.25% (7.5–7.75% for seniors), HDFC Bank 7.0–7.25%, ICICI Bank 7.0–7.10%, SBI 6.5–7.0% (7.0–7.5% for seniors). Post Office RD: 6.7% p.a. with Government of India guarantee — no DICGC limit applies. Senior citizens earn 0.50% extra at most banks. All Small Finance Bank RDs are DICGC-insured up to ₹5 lakh per depositor.
FD gives higher effective returns at the same rate because the full lump sum compounds from day one. ₹1,00,000 FD at 7% for 3 years = ₹1,22,504. Equivalent RD (₹2,778/month × 36 months) at 7% = ₹1,11,200. Choose FD if you have a lump sum ready. Choose RD if you earn a monthly salary and want savings discipline — it forces regular saving. The rate is usually identical for the same bank and tenure. Neither is superior in isolation; they solve different problems.
Post Office Recurring Deposit (PORD) offers 6.7% p.a. compounded quarterly in 2026. Tenure is fixed at 5 years (60 months). Minimum deposit: ₹100/month with no upper limit. Backed by the Government of India — the safest RD option with sovereign guarantee, unlike bank RDs limited to ₹5 lakh DICGC insurance. No TDS is deducted on Post Office RD interest, making it especially useful for investors near the ₹40,000 TDS threshold. Account can be extended for another 5 years at maturity.
Banks deduct 10% TDS if total RD interest at that bank exceeds ₹40,000/year (₹50,000 for senior citizens). Without PAN, TDS is 20%. To avoid TDS: submit Form 15G (below 60 years) or Form 15H (senior citizens) if total annual income is below ₹2.5 lakh (₹3 lakh for seniors). Spreading RDs across multiple banks keeps per-bank interest below the threshold. Post Office RDs have no TDS. TDS avoidance via form submission does not exempt the interest from income tax — you must still declare it in your ITR under "Income from Other Sources."
NRE (Non-Resident External) RD is for NRIs who earn income abroad and want to save in India. Key benefits: interest is fully tax-free in India, principal and interest are freely repatriable to any country, account is in Indian rupees. Interest rates: 6.5–7.5% at HDFC, ICICI, Axis, and SBI — comparable to domestic RD rates. Minimum tenure is 1 year. NRO RD (for income earned in India) has 30% TDS on interest. NRIs with rupee income streams should use NRE RD to avoid Indian tax liability on their foreign savings.
RD: guaranteed 6–8.5% returns, zero risk, DICGC-insured, ideal for goals under 3 years or emergency funds. SIP: historical 10–15% CAGR in equity funds over 10+ years, market-linked (can be negative short-term), long-term capital gains taxed at 12.5% above ₹1.25 lakh. Decision framework: if your goal is under 3 years, choose RD. If over 7 years, SIP typically wins significantly after tax. If risk tolerance is zero, RD always. Best strategy: fund 6-month emergency corpus via RD first, then invest monthly surplus in SIP for long-term goals like retirement or children's education.
