Goal · pure arithmetic

What would your goal actually require?

Corpus target, timeline, contributions — and the compound return the combination demands. The calculator does no forecasting and gives no advice; it shows the arithmetic your plan is implicitly assuming, so the assumption is a decision instead of a surprise.

Your plan

Monthly compounding; contributions land at month-end; taxes, costs and step-ups are ignored. Change a number and everything recomputes — nothing leaves your browser.

The honest arithmetic

Long-run context: broad Indian large-cap total-return indices have compounded at roughly 11–13% a year over multi-decade windows — with individual years anywhere between roughly −50% and +75%. A plan that needs more than the long-run band every single year is a plan about the assumption, not the market.
Drawdowns compound against you asymmetrically: a −30% year needs +43% to get back to even, and a −50% year needs +100%. Avoiding one large drawdown is worth more than several brilliant years.
The two levers that are always available: the contribution and the timeline. Both are decisions. The return is not.
