Why Compare SIP, RD, Lumpsum, & FD Side-by-Side?
Choosing the right financial instrument is a balancing act between risk, liquidity, and post-tax yields. While high-growth mutual fund SIPs compound aggressively over long horizons, fixed income vehicles like Fixed Deposits (FD) and Recurring Deposits (RD) provide unmatched capital safety.
Our advanced SIP vs FD vs RD Comparison Calculator acts as an intelligent playground. For any chosen timeframe, you can visually compare how a regular monthly investment behaves in an equity-oriented SIP vs a secure banking RD, and simultaneously evaluate how a bulk lumpsum principal compounds in an FD vs a post-tax inflation-adjusted Debt Fund portfolio.
How to Use the Comparison Tool
Enter your baseline parameters to check live comparative projections across all schemes instantly:
1. Scenario Baseline
Specify your Initial Lumpsum (Optional) and Monthly Investment limits. These bounds are used uniformly across all monthly calculators (SIP, RD) and bulk sum compounding calculators (Lumpsum, FD, Debt) to maintain baseline mathematical parity.
2. Set Return Targets
Customize the expected annual yields for each scheme. Alternatively, click the Growth Outlook Presets (Conservative, Balanced, Aggressive) to apply standard, SEBI-compliant market reference returns with one click.
3. Tax and Inflation adjustments
Select your exact Income Tax Slab to calculate accurate post-tax cash maturity. Check the "Adjust results for inflation?" box to convert nominal future values into real purchasing power in today's terms.
Mathematical Formulas & Compounding Theory
To maintain strict mathematical transparency, our planner uses standard financial industry formulas for discrete compound intervals:
Lumpsum (Compound Interest) Formula
For a one-time capital investment compounding annually:
Where $A$ is the final maturity value, $P$ is the principal invested, $r$ is the annual rate of interest, and $t$ is the holding period in years.
SIP (Future Value of Annuity) Formula
When investments are made regularly at periodic intervals (e.g., monthly):
Where $M$ is the cumulative maturity amount, $P$ is the monthly contribution, $i$ is the periodic rate of return ($i = r / 12$), and $n$ is the total number of monthly payments ($n = t \times 12$).
Fixed Deposit (FD) Quarterly Compounding Formula
Fixed deposits compound interest quarterly under standard Indian banking guidelines:
Where compounding frequency is locked to $4$ times a year. RD calculations follow identical quarterly compounding protocols.
Inflation Adjustment (Real Purchasing Power) Formula
Erosion of purchase power by inflation is determined by:
Where $\text{inf}$ is the expected average annual rate of inflation, and $t$ is the holding period in years.
Real-World Examples & Case Studies
Review these realistic, practical examples to align your investment strategies with real Indian market trends:
💼 Case Study 1: Retiring with ₹1.5 Crore via Step-up SIP
A 25-year-old financial analyst starts an equity mutual fund SIP of ₹10,000 per month at an expected CAGR of 12%.
- Without Step-up: In 25 years, the total principal invested is ₹30 Lacs, and the accumulated corpus is ₹1.89 Crore.
- With 10% Annual Step-up: By stepping up the monthly contribution by 10% each year as their salary grows, the final corpus balloons to ₹4.48 Crore!
- Real Value (5% Inflation adjusted): The purchasing power of that ₹4.48 Crore in today's money is worth approximately ₹1.32 Crore.
🎓 Case Study 2: Funding Child's Higher Education Abroad
A parent estimates they will need ₹50 Lacs in 10 years for their child's professional degree. They select the Goal Planner mode assuming a moderate mutual fund return rate of 11% p.a.
- Standard Goal calculation: They must invest ₹23,086 per month for 10 years to reach ₹50 Lacs.
- Adjusted for Inflation (5%): In 10 years, educational costs will rise. The real target becomes ₹81.4 Lacs. To reach this adjusted goal, they need to save ₹37,597 per month.

Frequently Asked Questions (FAQ)
1. Which option among SIP, RD, and FD is best for me?
If your investment horizon is long-term (5+ years) and you can tolerate market volatility, SIP is the best option. If you prefer safe and guaranteed returns for the short-to-medium term, Fixed Deposits (for lump sum amounts) or Recurring Deposits (for monthly savings) are highly secure.
2. How do inflation-adjusted calculations change the investment results?
Inflation gradually reduces the purchasing power of your money over time. If your nominal return rate is 8% and inflation is 6%, your real rate of return is effectively 2%. Enabling the inflation adjustment feature shows the true value of your future accumulated wealth in today's terms.
3. Is interest earned on bank FDs and RDs taxable?
Yes, interest earned on bank FDs and RDs is taxable according to your individual income tax slab rate (10%, 20%, or 30%), which banks deduct annually as TDS. By selecting your tax slab in this comparison tool, you can see your actual post-tax maturity value directly.
