Understand the calculation

What is a Goal Planning Lumpsum Calculator?

This calculator discounts a future funding gap back to today. It is useful when you have a bonus, maturity proceeds or other one-time capital and want to know how much of it would need to be invested now.

Existing investments are projected separately so the result shows the additional lumpsum required rather than pretending you are starting from zero.

Present value of the remaining goal

Required today = (future target − future value of existing corpus) ÷ (1 + expected return)^years

The target can first be increased by an optional inflation rate. Return and inflation assumptions remain editable because neither is guaranteed.

Why the result is sensitive to time

The longer the remaining horizon, the more of the final target the assumed investment growth is expected to provide. That is helpful mathematically but also makes the plan more sensitive to whether the assumed return actually occurs.

Frequently asked questions

What if existing investments already cover the goal?

The additional required lumpsum becomes zero once the projected value of existing investments meets or exceeds the target.

Is a higher return assumption better?

It produces a smaller required investment mathematically, but it also increases planning risk if the return does not materialise.

Can I use this for ₹50 lakh or ₹5 crore?

Yes. The calculator is target-agnostic and is deliberately not split into separate pages for different round-number goals.
