FD vs Mutual Fund vs RD Calculator India: Compare Real Post-Tax Wealth

Comparing a 7.0% bank Fixed Deposit against a 12.0% Mutual Fund SIP by looking only at pre-tax interest rates hides half the real story. Once Indian income tax rules and 5.5% retail inflation step in, a guaranteed FD in the 30% tax slab can actually lose purchasing power over five years, while an equity SIP keeps nearly 88% to 100% of its gains after Section 112A exemptions. On the flip side, equity funds carry real short-term drawdown risk that can wreck a 12-month goal. This FD vs Mutual Fund vs RD Calculator runs all three instruments side-by-side after tax and inflation for FY 2025-26.

What Is an FD vs Mutual Fund vs RD Calculator?

This three-way comparison tool evaluates India’s three most popular retail wealth vehicles on an apples-to-apples post-tax and real-purchasing-power basis: Bank Fixed Deposits (FD) for lump-sum capital protection, Recurring Deposits (RD) for guaranteed monthly savings, and Mutual Fund SIPs (Equity or Debt) for market-linked wealth compounding. Most bank calculators stop at “Gross Maturity Value,” ignoring the fact that FD and RD interest is taxed at up to 30% + cess while long-term equity gains enjoy a ₹1,25,000 annual exemption and a 12.5% cap.

Meet Kavita, a 31-year-old product marketing lead in Hyderabad sitting in the 30% Old/New tax slab. She wants to build a home down-payment fund over 5 years and can commit ₹10,000 every month (₹6,00,000 total cash outflow) — or deploy an existing ₹6,00,000 bonus lump sum. Unsure whether to set up a 6.8% bank RD, lock ₹6,00,000 into a 7.0% FD, or run a 12.0% Nifty 50 Index Fund SIP, Kavita plugs her numbers into the calculator at 5.5% inflation. Within seconds, she sees the exact rupee gap after taxes and inflation.

How the FD, RD & Mutual Fund Formulas Work (With Worked Example)

Each of the three instruments compounds on a different mathematical schedule and faces its own FY 2025-26 tax rule:

• Fixed Deposit (Quarterly Compounding): M = P × (1 + r/4)^(4 × t); full interest taxed at your marginal slab rate.
• Recurring Deposit (Monthly Instalment, Quarterly Compounding): Each monthly deposit R accrues interest settled at quarter-end; total interest taxed at your marginal slab rate.
• Equity Mutual Fund SIP (Monthly Compounding): M = R × [((1 + i)^n − 1) ÷ i] × (1 + i) where i = annual rate ÷ 12; gains held >12 months taxed at 12.5% only on gains above ₹1,25,000 u/s 112A.

Let’s compare Kavita’s 5-Year (60-month) outcomes at a 30% tax slab and 5.5% inflation across ₹6,00,000 total capital:

• Option A — Recurring Deposit (₹10,000/mo @ 6.8% p.a.): Total invested = ₹6,00,000. Gross maturity = ₹7,14,560 (Interest = ₹1,14,560). Minus 30% slab tax (₹34,368) = ₹6,80,192 post-tax. Adjusted for 5.5% inflation over 5 years (÷ 1.055^5), real purchasing power in today’s rupees = ₹5,20,438.
• Option B — Equity Mutual Fund SIP (₹10,000/mo @ 12.0% p.a.): Total invested = ₹6,00,000. Gross maturity = ₹8,24,864 (Gain = ₹2,24,864). Minus ₹1,25,000 LTCG exemption leaves ₹99,864 taxable × 12.5% = ₹12,483 tax → ₹8,12,381 post-tax (Real value = ₹6,21,580). Kavita finishes ₹1,32,189 ahead of the RD on the exact same ₹10,000 monthly outlay!
• Option C — Lump-Sum Fixed Deposit (₹6,00,000 Day-1 @ 7.0% p.a.): Gross maturity = ₹8,48,867 (Interest = ₹2,48,867). Minus 30% tax (₹74,660) = ₹7,74,207 post-tax (Real value = ₹5,92,371). For standalone lump-sum or step-up projections, test your numbers in our SIP Calculator and FD Calculator.

Side-by-Side Matrix: FD vs RD vs Equity MF vs Debt MF (FY 2025-26)

Choosing the right bucket is never an all-or-nothing bet — most balanced Indian portfolios combine FDs/RDs for short-term certainty with equity SIPs for multi-year wealth creation. Here is how all four options stack up under FY 2025-26 tax and regulatory rules:

Goal-Horizon Matching and Tax-Harvesting Strategies

Use a strict Time-Horizon Bucket Rule before moving money. Money needed inside 0 to 24 months (emergency fund, car down payment, upcoming tuition) does not belong in pure equity SIPs — if Nifty corrects 22% in Month 18, rupee-cost averaging won’t rescue your principal in time. Keep 0–24 month funds in sweep-in bank FDs, RDs, or — if you sit in the 30% bracket — Arbitrage Mutual Funds, which deliver ~7% low-volatility returns while qualifying for equity taxation (zero tax up to ₹1.25 lakh LTCG after 12 months!). For 3 to 5 year goals, Hybrid Aggressive or Balanced Advantage Funds smooth volatility while preserving equity LTCG treatment.

For 5 to 15+ year goals, equity SIPs enjoy a hidden compounding boost: annual LTCG tax harvesting. Because Section 112A exempts ₹1,25,000 of realized long-term equity gains every financial year, redeeming and immediately repurchasing units held over 12 months resets your cost basis higher each March without paying a rupee of tax. Contrast that with a bank FD, where annual TDS and slab tax shave compound growth along the way, steadily eroding real wealth as you can verify in our Inflation Calculator.

Common Mistakes People Make With FD vs Mutual Fund Comparisons

• Comparing a ₹1,00,000 lump-sum FD directly against a ₹10,000/month SIP without checking total capital invested: Over 5 years, ₹10,000/month invests ₹6,00,000 total versus ₹1,00,000 in the FD! Always inspect the “Effective Rate” and “Total Invested” rows in our comparison table so you evaluate return efficiency per rupee deployed.
• Ignoring FIFO unit taxation on monthly SIP redemptions: In a 15-month SIP, only your first 2 monthly SIP instalments have crossed the 12-month LTCG mark! Redeeming the entire corpus at Month 15 subjects the most recent 12 monthly instalments to 20% Short-Term Capital Gains tax u/s 111A under First-In-First-Out (FIFO) accounting.
• Selecting Regular Mutual Fund plans instead of Direct plans: Buying mutual funds through bank relationship managers puts you in Regular plans carrying a 0.75% to 1.25% higher annual expense ratio than Direct plans. On a ₹15,000/month SIP over 15 years at 12%, a 1% trail commission quietly drains over ₹6.4 lakh from your final corpus.
