FD Calculator
See how a fixed deposit may grow with quarterly, monthly, or annual compounding. Test deposit amount, rate, and tenure, then calculate pre-tax vs post-tax maturity value.
Fixed Deposit Calculator
Estimate maturity amount, total interest earned, annual growth path, and post-tax returns with a cleaner premium bank-style planning experience.
👉 Try switching quarterly to monthly compounding or extending tenure from 5 to 7 years to see how the maturity value may change over time.

Why this FD calculator is useful
This FD calculator is designed for practical deposit planning, not just one final number. It helps users interpret maturity, interest, compounding, and tax impact clearly.
Uses the classic fixed deposit maturity formula with adjustable compounding frequency and tenure.
Shows maturity value, annual progression, and post-tax estimate instead of only a single output line.
Lets users compare common rate scenarios quickly and understand how small rate changes affect maturity.
FD Planning Scenarios
Use quick presets for common deposit goals. These scenarios auto-fill the calculator with a practical starting setup.
How to use the FD Calculator
If you deposit ₹5,00,000 at 7.2% for 5 years with quarterly compounding, your maturity value can reach around ₹7.14 lakh. This FD calculator helps estimate that clearly.
1 Enter your deposit amount
Start with the amount you plan to place in a fixed deposit. This can be a short-term reserve, a bonus, or part of a goal-based savings plan.
4 Select compounding frequency
Quarterly compounding is common in bank FDs, but some products may differ. More frequent compounding can improve the maturity value slightly.
2 Add the expected FD rate
Use the annual interest rate offered by your bank or NBFC. Small changes in rate can meaningfully affect maturity over longer tenures.
5 Check post-tax value too
FD interest is taxable. Looking only at the gross maturity can give an incomplete picture, especially for larger deposits.
3 Choose the tenure carefully
A longer deposit term increases interest earned, but it also reduces liquidity. Tenure should match the timing of the financial goal.
6 Review the annual growth table
The year-wise table and chart help users see how steadily a fixed deposit grows and how much of the final amount comes from interest.
FD Formula & Calculation Logic
This calculator uses the standard compound interest logic for fixed deposits and adds a simple post-tax estimate for more practical planning.
Base FD formula
The maturity value of a fixed deposit with compounding is commonly calculated as:
- P = Principal deposit amount
- r = Annual interest rate
- n = Compounding frequency per year
- t = Tenure in years
What this calculator adds
Along with maturity value, this tool shows interest earned, year-wise progression, annualised growth, and a simple post-tax estimate based on the tax rate you choose.
That makes it more useful for planning than a basic maturity-only FD calculator.
Important Assumptions to Keep in Mind
FD outcomes are predictable compared with market-linked products, but interpretation still depends on rate, tax bracket, inflation, and liquidity needs.
Rate is fixed only for the booked FD
The selected rate applies to the deposit being planned. Future FD bookings may offer higher or lower rates depending on the interest cycle.
Tax can reduce net return meaningfully
Users in higher tax brackets may find the post-tax value much less attractive than the gross maturity amount suggests.
Liquidity still matters
Premature withdrawal can change the effective return. Fixed deposits work best when the tenure matches the actual need horizon.
Inflation can erode real purchasing power
Even stable FD returns may not always keep pace with inflation. This is important for longer tenures and real-value planning.
Quick FD Insights
These are the practical patterns users usually notice while comparing deposit amount, rate, compounding frequency, and tenure.
Tenure steadily lifts maturity
Longer tenures increase total interest meaningfully, especially when the deposit is left untouched throughout the term.
Small rate differences add up
The gap between 6.5% and 7.5% may look small, but it can create a notable difference in maturity over several years.
Compounding matters, but not dramatically
Monthly compounding may produce slightly better maturity than quarterly or annual compounding, though the impact is usually moderate.
Post-tax return is the real planning number
For many users, the post-tax maturity estimate is more useful than the headline FD rate while comparing options.
Common FD Mistakes to Avoid
Even a safe fixed deposit can become inefficient if basic planning mistakes are ignored.
Ignoring tax impact
Comparing deposits only on headline interest rate without considering tax can overstate your actual gain.
Locking too much money
Putting emergency funds into long-tenure FDs can reduce flexibility if you need liquidity unexpectedly.
Chasing rate without checking institution quality
A slightly higher rate should still be weighed against safety, credibility, and liquidity terms.
Using FD for all long-term goals
For goals far away, FD may provide stability but not always the strongest inflation-adjusted growth.
FD vs RD vs Savings Account
All three serve different purposes. The right choice depends on whether you already have a lump sum and how much liquidity you want.
Fixed Deposit
- Best when you already have a lump sum to park
- Usually offers a higher rate than a savings account
- Suitable for predictable, low-volatility outcomes
- Liquidity may reduce if withdrawn early
RD / Savings
- RD works better when you want to save monthly instead of one-time
- Savings accounts offer the highest flexibility but lower returns
- RD builds disciplined deposits; FD suits parked funds
- Choice depends on cash flow and goal timing
