A Systematic Investment Plan (SIP) calculator is a financial tool that helps you estimate the potential returns on your mutual fund investments made through SIPs. It shows how regular monthly investments can grow over time through the power of compounding.
How a SIP Calculator Works
The SIP calculator uses the future value of annuity formula:
FV = P × ((1+r)^n - 1)/r × (1+r)
Where:
- •P = Monthly investment amount
- •r = Expected monthly return rate (annual rate / 12 / 100)
- •n = Total number of monthly installments
The formula accounts for each monthly installment growing for different periods - the first installment grows for the entire tenure while the last installment grows for only one month.
How to Use a SIP Calculator
Using our SIP Calculator is simple:
1. Enter Monthly Investment: Start with any amount from ₹500 to ₹5,00,000
2. Set Expected Return Rate: For equity funds, use 10-15%; for debt funds, use 6-8%
3. Choose Investment Period: SIPs work best for 7+ years
4. Enable Step-Up (Optional): Add annual increase to boost returns
Example: ₹10,000 Monthly SIP for 10 Years
Step-Up SIP: A Smarter Strategy
A step-up SIP increases your investment amount annually, typically by 10%. This aligns your investments with your growing income.
Example: ₹10,000/month with 10% annual step-up for 15 years at 12% returns:
- •Year 1: ₹10,000/month
- •Year 5: ₹14,641/month
- •Year 10: ₹23,579/month
- •Year 15: ₹37,790/month
- •Total Corpus: ~₹76.3 lakh vs ₹50.5 lakh without step-up

SIP vs Lumpsum: Which is Better?
SIP is better for regular investors who want to minimize market timing risk. Lumpsum is better for one-time investments. For large amounts, consider STP (Systematic Transfer Plan). Compare both strategies with our SIP vs Lumpsum Comparison.
