Why use a SIP calculator?
A SIP calculator helps you estimate how regular investing may grow over time. It turns monthly contributions, expected returns, and time horizon into a clearer picture of possible future value, helping you plan with more confidence.
What this calculator helps you do
- Estimate future value of one-time investments
- Compare expected returns across time periods
- Review total gains before investing surplus cash
- Compare lumpsum and SIP outcomes on the same page
Who should use it
- People starting a regular investing habit
- Investors comparing SIP and lump sum approaches
- Households planning for long-term goals
- Anyone evaluating how accumulation may support future withdrawals
Lumpsum vs SIP calculator
Lumpsum investing puts the full amount to work immediately, while SIP spreads investment across months. Comparing both helps you understand trade-offs between cash flow, timing risk, and compounding time.
SIP for accumulation
SIP helps you invest steadily over time instead of depending on one large contribution. It can be useful for long-term planning when consistency matters more than perfect timing.
Step-Up SIP for growing contributions
Step-Up SIP models what happens if you increase your contribution periodically, which may be useful when income rises over time.
SWP for later withdrawals
SWP helps you estimate how an accumulated corpus may support ongoing withdrawals while the remaining balance continues to earn returns.
SIP vs lump sum
SIP and lump sum investing serve different situations. SIP suits regular contribution planning, while lump sum is useful when you already have capital ready to invest. This page lets you compare both in one place.
Why comparison matters
Comparing investing paths helps you choose the approach that better fits your cash flow, time horizon, and comfort with market timing.

Frequently asked questions
What is a lumpsum calculator?
It calculates the estimated future value and gains from a one-time investment over a selected period.
Is lumpsum better than SIP?
Lumpsum may benefit from more time in the market, while SIP can be easier for regular cash flow and timing risk management.
Can I use it for mutual funds?
Yes. You can estimate potential mutual fund growth using your expected annual return assumption.
Does the calculator include tax?
No. The result is a growth estimate before tax, exit load, or other product-specific costs.
Formula and trust notes
SIP projections use monthly compounding from your contribution, expected annual return, and duration. Lumpsum projections use standard compound growth, while SWP estimates monthly withdrawals after applying the assumed monthly return.
