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.
Compounding Mathematics & Investment Formulas
Standardized mathematical compounding structures loaded natively within other comparative tools:
1. Lumpsum (Compound Interest) Formula
For a single bulk one-time capital investment compounding annually:
Where A is the final wealth maturity amount, P represents your initial lumpsum investment principal, r is the annualized expected return rate, and t is the cumulative tenure in years.
2. SIP (Future Value of Annuity) Formula
For systematic recurring monthly contributions compounding at regular intervals:
Where M represents your total accrued systematic maturity sum, P is the fixed monthly contribution amount, i is the periodic monthly returns rate i=r12, and n indicates the absolute number of installments over the duration (n = t × 12).
3. Fixed Deposit (FD) Quarterly Compounding Formula
Fixed income bank deposits compound interests quarterly under Indian commercial banking standards:
Where the compounding cycle is executed 4 times per year. Recurring Deposit (RD) models calculate quarterly compound interests based on standard composite staggered series values.
4. Inflation Adjustment (Real Purchasing Power) Formula
Measures the erosive effect of consumer price inflation over time:
Where inf is the expected average annual rate of consumer price index inflation ( CPI, historically 4.5% - 6% in India) and t is the cumulative tenure in years.
Real-World Examples & Case Studies
Review these realistic, practical examples to align your investment strategies with real Indian market trends:
1 Retiring with ₹1.5 Crore via Step-up SIP
Step-up StrategyA 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.
2 Funding Child's Higher Education Abroad
Goal TargetA 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.
