- Project SIP growth from regular monthly investing
- Compare SIP and lumpsum investing in one place
- Test Step-Up SIP scenarios as income increases
- Estimate how withdrawals may affect corpus sustainability
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
SIP calculator with Step-Up, SWP, and Lumpsum modes
Use this page when you want a broader mutual fund planning view: monthly SIP for accumulation, Step-Up SIP for growing contributions, lumpsum for one-time investing, and SWP for future withdrawals.
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.

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.
