After tax. After inflation. The real number — not what your bank tells you.

Real return is the actual return on your investment after adjusting for both tax and inflation. Most Indians focus on the nominal interest rate — the number their bank advertises. But this number is misleading because it does not account for two major deductions: the tax you pay on the interest earned, and the purchasing power lost to inflation.
For example, a 7% Fixed Deposit sounds attractive. But if you are in the 30% income tax slab, your post-tax return drops to 4.9%. After adjusting for 6% inflation using the Fisher Equation, your real return is approximately −1.04% per year. Your bank balance grows, but your purchasing power actually shrinks every year.
In contrast, a Systematic Investment Plan (SIP) in an equity mutual fund at 12% CAGR — after 12.5% LTCG tax with ₹1.25 lakh exemption and 6% inflation — delivers approximately +5.66% real return per year. Over 10 to 15 years, this difference compounds dramatically.
The comparison between Fixed Deposits and Mutual Fund SIPs is not straightforward because it depends on your tax slab, investment horizon, and the prevailing inflation rate. For investors in the 20% or 30% tax slab with a horizon of 5 years or more, equity mutual funds consistently deliver higher real returns than FDs.
FD interest is taxed at your income slab rate (up to 30%), while Mutual Fund Long Term Capital Gains (LTCG) are taxed at only 12.5% with a ₹1.25 lakh annual exemption under the Union Budget 2024. This tax efficiency makes mutual funds significantly more advantageous for long-term wealth creation.
However, FDs are safer and more predictable for short-term goals (under 3 years), emergency funds, and for investors who cannot tolerate market volatility. The right answer depends on your specific situation — which is exactly what our free calculator helps you determine.
Our Financial Reality Engine compares FD, RD (Recurring Deposit), and Mutual Funds side by side showing three layers of returns: the nominal corpus (what your statement shows), the post-tax corpus (after income tax or LTCG), and the real value in today's money (after inflation adjustment).
Simply enter your investment amount, duration, interest rate or expected CAGR, your income tax slab, and the expected inflation rate. The calculator uses the Fisher Equation for mathematically accurate real return calculations — the same method used by economists and financial planners.

For someone in the 30% tax slab with 6% inflation, a 7% FD gives a real return of approximately −1.04% per year. Post-tax return is 4.9% (7% × 0.7), and after adjusting for 6% inflation using the Fisher Equation, the real return is negative. You are losing purchasing power despite earning interest.
FD is capital-safe but not inflation-safe for investors in the 20-30% tax bracket. With current FD rates of 6.5-7.5% and inflation at 5-6%, most FD investors earn zero or negative real returns. For capital safety with better real returns, consider PPF (tax-free) or short-duration debt mutual funds.
As per Union Budget 2024, Long Term Capital Gains (LTCG) on equity mutual funds held for more than 1 year are taxed at 12.5% (reduced from 10%). The annual exemption limit is ₹1.25 lakh (increased from ₹1 lakh). LTCG above ₹1.25 lakh per year is taxed at 12.5% without indexation benefit.
The Fisher Equation calculates real return as: Real Return = ((1 + Nominal Return) / (1 + Inflation Rate)) − 1. This is more accurate than the simple approximation of subtracting inflation from nominal return. For example, 7% FD at 30% tax (post-tax 4.9%) with 6% inflation: Real Return = (1.049 / 1.06) − 1 = −1.04%.
