FD vs Mutual Funds Returns Estimator - Investment Yield Comparison
Compare pre-tax and post-tax maturity returns between a Fixed Deposit and a Mutual Fund, including income-slab FD taxation and LTCG rules on mutual fund gains.
AI Quick Summary
Definition & Purpose:
This calculator compares the post-tax maturity value of a Fixed Deposit — taxed annually at your income slab rate — against a Mutual Fund investment, taxed once at redemption under long-term capital gains (LTCG) rules, including India's statutory LTCG exemption.
When to Use:
Use this calculator to compare the real, after-tax return of a guaranteed Fixed Deposit against a market-linked Mutual Fund investment, rather than comparing their headline interest and return rates directly.
Key Takeaway Insights:
- Fixed deposit interest is taxed every year at your income slab rate whether or not you withdraw it, while mutual fund gains compound completely untaxed until the investment is actually redeemed — this tax-deferred compounding is a real structural advantage for mutual funds, separate from any difference in expected return rate.
- For INR-denominated mutual fund investments, the calculator subtracts a ₹1,25,000 statutory LTCG exemption from the gain before applying the capital gains tax rate — this exemption doesn't apply to FD interest, which is taxed on every rupee earned above zero.
- A higher expected mutual fund return doesn't automatically mean a higher post-tax outcome is guaranteed — mutual fund returns are market-linked and can fall short of the assumed rate, while FD returns are contractually guaranteed at the stated rate for the deposit term.

Introduction
FD vs Mutual Funds Returns Estimator – Tax & Yield Guide
Comparing a Fixed Deposit against a Mutual Fund by headline rate alone is misleading, because the two are taxed under entirely different rules. This calculator projects the pre-tax maturity, tax paid, and post-tax maturity value for both, so the comparison reflects what an investor would actually keep.
How Each Investment Is Taxed and Compounded
Fixed Deposit — interest taxed annually at the income slab rate, then compounded quarterly:
R_post = R_FD × ≤ft(1 - (Tax Slab / 100)) qquad Post-Tax FD = P × ≤ft(1 + fracR_post400)^4t
Mutual Fund — compounds untaxed, then taxed once at redemption:
Pre-Tax MF = P × ≤ft(1 + fracR_MF100)^t qquad Taxable Gain = max(0, Gain - Exemption)
Post-Tax MF = Pre-Tax MF - ≤ft(Taxable Gain × (LTCG Rate / 100))
For INR investments, a statutory ₹1,25,000 exemption is subtracted from the mutual fund gain before applying the LTCG rate.
Worked Example
₹10,00,000 invested for 5 years at a 7% FD rate (30% tax slab) versus a 12% expected mutual fund return (12.5% LTCG tax):
Fixed Deposit:
- Post-tax rate: 7 × (1 - 0.30) = 4.9%
- Post-tax maturity: 10,00,000 × (1 + 4.9/400)^20 ≈ ₹12,75,721.01
- Tax paid: ₹14,14,778.20 - ₹12,75,721.01 = ₹1,39,057.18
Mutual Fund:
- Pre-tax maturity: 10,00,000 × (1.12)^5 ≈ ₹17,62,341.68
- Gain: ₹17,62,341.68 - ₹10,00,000 = ₹7,62,341.68
- Taxable gain (after exemption): ₹7,62,341.68 - ₹1,25,000 = ₹6,37,341.68
- LTCG tax: ₹6,37,341.68 × 12.5% ≈ ₹79,667.71
- Post-tax maturity: ₹17,62,341.68 - ₹79,667.71 ≈ ₹16,82,673.97
The mutual fund's post-tax maturity of ₹16,82,673.97 outperforms the FD's ₹12,75,721.01 by ₹4,06,952.96 — driven both by the higher assumed return and by paying tax only once, at redemption, instead of every year.

Worked Examples Calculation
15-Year ₹10,00,000 Investment: 7% FD @ 30% Tax Slab vs. 12% MF @ 12.5% LTCG Tax
Principal = ₹10,00,000, Tenure = 5 Years, FD Rate = 7%, Tax Slab = 30%, MF Rate = 12%, LTCG Tax Rate = 12.5%
FD: Post-tax rate = 7 × (1 - 0.30) = 4.9%. Post-Tax FD = 10,00,000 × (1 + 4.9/400)^20 = ₹12,75,721.01. Tax Paid = ₹1,39,057.18. MF: Pre-Tax = 10,00,000 × (1.12)^5 = ₹17,62,341.68. Gain = ₹7,62,341.68. Taxable Gain (after ₹1.25L exemption) = ₹6,37,341.68. LTCG Tax = 6,37,341.68 × 12.5% = ₹79,667.71. Post-Tax MF = ₹16,82,673.97.
FD Post-Tax Maturity = ₹12,75,721.01 | MF Post-Tax Maturity = ₹16,82,673.97 | MF Outperformance = ₹4,06,952.96
2Same Inputs, Shorter 3-Year Tenure
Principal = ₹10,00,000, Tenure = 3 Years, FD Rate = 7%, Tax Slab = 30%, MF Rate = 12%, LTCG Tax Rate = 12.5%
Over a shorter 3-year tenure, MF gains before the ₹1,25,000 exemption are smaller, so a larger share of the gain escapes LTCG tax entirely, but there's also less time for the mutual fund's growth advantage to compound: FD Post-Tax = ₹11,57,319.91. MF Post-Tax = ₹13,69,937.00.
FD Post-Tax Maturity = ₹11,57,319.91 | MF Post-Tax Maturity = ₹13,69,937.00 | MF Outperformance = ₹2,12,617.09

Limitations & Common Mistakes
- Entering incompatible unit formats (e.g. Mixing Metric and Imperial).
- Typographical mistakes in numeric entry fields.
Assumes a single constant FD rate and a single constant expected mutual fund return for the entire tenure — mutual fund returns are not guaranteed and can vary significantly from the assumed rate. The ₹1,25,000 LTCG exemption is only applied when the currency is set to INR; other currencies apply the entered capital gains tax rate to the full taxable gain with no exemption.
Frequently Asked Questions (FAQ)
Q:How are Fixed Deposits taxed compared to Mutual Funds?
FD interest is taxed every financial year at your marginal income tax slab rate, regardless of whether you withdraw the interest or let it reinvest. Mutual fund gains, by contrast, are only taxed once — when you actually redeem your units — under capital gains rules, which for equity funds held over a year (long-term) means a lower LTCG rate rather than your full income slab rate.
Q:What is the LTCG tax exemption on equity mutual funds in India?
Under current Indian rules, long-term capital gains on equity mutual funds held over 12 months are exempt from tax up to ₹1,25,000 per financial year — only gains above that threshold are taxed at the LTCG rate. This calculator applies that exemption automatically when the currency is set to INR.
Q:Why do mutual funds often deliver higher post-tax returns than FDs?
Two factors compound together: mutual funds are typically assumed to earn a higher expected return than FD interest rates, and mutual fund gains grow completely untaxed until redemption rather than being taxed annually. Both effects favor mutual funds in this comparison, though the mutual fund's return is an assumption, not a guarantee, unlike the FD's contracted rate.
Q:Are mutual fund returns guaranteed?
No. Fixed deposits offer a guaranteed, contracted interest rate for the deposit term. Mutual funds are market-linked investments whose actual returns depend on market performance and can be higher or lower than any assumed rate — including negative in a down market — so the mutual fund figures here are a projection, not a promise.
