Cumulative vs Non-Cumulative FD Calculator
💡 Key Tips for FD Investors
- Choose Cumulative FD for wealth creation — interest compounds silently and pays out as a lump sum at maturity, giving significantly higher total returns.
- Choose Non-Cumulative FD for regular income — ideal for retirees or anyone who needs predictable monthly or quarterly cash flow.
- Senior citizens (60+) earn an additional 0.25–0.75% — always book under the senior citizen category if eligible.
- Spread large deposits across multiple banks to stay within the ₹5 lakh DICGC insurance per bank per depositor.
- Use FD laddering — split corpus into multiple FDs with different maturities for better liquidity and rate optimisation.
- Tax-saver FDs (5-year lock-in) qualify for Section 80C deduction up to ₹1.5 lakh per year, but interest is still taxable.
⚠ Investing Cautions
- FD interest is fully taxable and added to your income at your slab rate. Post-tax returns often trail inflation for investors in the 20–30% bracket.
- Banks deduct 10% TDS if annual interest exceeds ₹40,000 (₹50,000 for senior citizens). Submit Form 15G/15H at the start of each year to avoid TDS if you’re not taxable.
- Non-cumulative FDs appear to pay less total interest — this is because payouts are not reinvested, so there is no compounding benefit.
- Premature withdrawal carries a penalty of 0.5–1% — plan your tenure carefully before locking in.
- NBFC FDs are not covered under DICGC insurance — always verify the credit rating (AAA or AA+) before investing.

Cumulative vs Non-Cumulative FD: Complete Guide to Fixed Deposit Calculator
What Are Cumulative and Non-Cumulative FDs?
When you open a Fixed Deposit in India, you face one critical choice before everything else: do you want your interest paid out periodically, or compounded and paid at maturity? This single decision determines whether your FD is cumulative or non-cumulative — and it significantly affects your total returns.
Cumulative FD: Interest is reinvested and compounded quarterly. You receive the full maturity amount (principal + all compounded interest) at the end of the tenure. Best for wealth creation.
Non-Cumulative FD: Interest is paid out at your chosen frequency (monthly, quarterly, half-yearly, or yearly). The principal remains unchanged and is returned at maturity. Best for regular income.
Key Insight: Same deposit. Same rate. Same tenure. But cumulative FD earns more total interest because the unpaid interest continues to compound. Example: Rs. 1,00,000 at 7% for 3 years — Cumulative earns Rs. 22,987, Non-Cumulative (quarterly) pays out Rs. 21,000 total. Difference: Rs. 1,987 purely from compounding.
How the Calculator Works
Cumulative FD Formula
M = P x (1 + r/n)^(n x t)
| Variable | Meaning | Example |
|---|---|---|
| M | Maturity Amount | Rs.1,22,987 |
| P | Principal Deposited | Rs.1,00,000 |
| r | Annual Rate (decimal) | 0.07 |
| n | Compounding per year | 4 (quarterly) |
| t | Time in years | 3 |
Non-Cumulative FD Formula
Periodic Payout = P x (r / n)
The principal remains unchanged throughout the tenure. Total interest = Periodic Payout x (n x t). No compounding applies — you receive fixed payouts at regular intervals.
Step-by-Step Guide: Using the Calculator
- Open the FD Calculator and select your FD Type — Cumulative or Non-Cumulative using the toggle button.
- Enter your Deposit Amount — the lumpsum you plan to invest (e.g. Rs.1,00,000).
- Set the Annual Interest Rate — check your bank’s current rate (typically 6.5–8% for 2025). Senior citizens: add the senior premium.
- Choose the Time Period — 1 to 10 years, depending on your goal.
- For Non-Cumulative: select your Payout Frequency — Monthly, Quarterly, Half-Yearly, or Yearly.
- Click “Calculate Returns” — view Maturity Amount (or Periodic Payout), Total Interest, Absolute Returns %, Effective Annual Yield, and a year-wise or period-wise breakdown table.
- Switch between Cumulative and Non-Cumulative to instantly compare results for the same deposit — and choose the mode that fits your goal.

Frequently Asked Questions (FAQs)
Cumulative FD always gives more total interest because the periodic interest is reinvested and compounds. In a non-cumulative FD, each payout is removed and no longer earns interest. The difference grows larger with longer tenures and higher interest rates.
For cumulative FDs, banks calculate accrued interest annually and deduct TDS when it crosses Rs.40,000 (Rs.50,000 for senior citizens) in a year — even though you have not received the money. For non-cumulative FDs, TDS is deducted at the time of each payout. Submit Form 15G or 15H at the start of each financial year to avoid TDS if your total income is below the taxable limit.
No. The FD type is fixed at the time of booking. To switch, you would need to break the existing FD (with a premature withdrawal penalty of 0.5–1%) and rebook a new one. Plan your FD type carefully based on your income needs before booking.
The principal remains entirely unchanged throughout the tenure. Only interest is paid out periodically. At maturity, you receive the full original principal back. This makes non-cumulative FDs popular for retirees who want income without eroding capital.
Yes. Monthly compounding > Quarterly > Half-Yearly > Yearly in terms of total returns. However, most Indian bank FDs use quarterly compounding as the standard for cumulative deposits. The difference between monthly and quarterly compounding at 7% is roughly 0.04% per year — small but meaningful over 10 years.
Yes. Both cumulative and non-cumulative FDs are eligible for loans of 70–90% of the deposit value at an interest rate typically 1–2% above the FD rate. This lets you access funds without breaking the FD or losing your periodic interest payouts.
Cumulative FDs tend to be slightly better for tax planning because interest is only “realised” at maturity — though TDS is still deducted annually on accrued interest. If you are in a lower tax bracket now but expect to be in a higher one later, non-cumulative FDs may help you receive and declare income at lower slab rates in the current year.
EAY is the true annual return accounting for compounding frequency. At 7% quarterly, EAY = 7.19%. This matters when comparing FDs across banks — one bank offering 7.1% monthly compounding may give better returns than another offering 7.25% yearly compounding. Always compare FDs using EAY, not the nominal rate printed on the offer.
Conclusion
Choosing between a Cumulative and Non-Cumulative FD is not about which is better in absolute terms — it is about which fits your life better right now. If you do not need income from your deposit, go with a cumulative approach and let compounding quietly multiply your wealth. If you depend on your FD for monthly or quarterly expenses, go non-cumulative and enjoy predictable, guaranteed payouts.
