Question 1

How is the required monthly contribution calculated?

Accepted Answer

We work backward from your goal: given your current savings, timeframe, and expected return, we solve for the exact monthly contribution that grows your investments to your target amount by the end of that timeframe.

Question 2

What if I'm already on track without contributing more?

Accepted Answer

If your current savings alone, compounded at your expected return, will already reach your goal by your target date, we show a required contribution of $0 — you're already there.

Question 3

What return rate should I use?

Accepted Answer

Use a rate that reflects your actual investment mix — a diversified stock portfolio has historically returned around 6-7% (inflation-adjusted) over the long run, while a more conservative mix would be lower. Use a conservative estimate you're comfortable with.

Question 4

Does this account for inflation?

Accepted Answer

If you enter your goal amount in today's rupees and use a real (inflation-adjusted) return rate, the result is already in today's purchasing power — the standard way to plan for a future goal in the money you understand today.

Question 5

What's the difference between 'total contributed' and 'total growth'?

Accepted Answer

Total contributed is the sum of all your monthly contributions. Total growth is the extra amount your money earns from investment returns on top of what you put in — the part compounding does for you.

Question 6

Can I save or share my results?

Accepted Answer

Yes — use Share to copy a link that reproduces your exact inputs, or log in to save your calculation and revisit it later from your history.
