Every calculator

Nineteen calculators, grouped by the question you are actually asking rather than by product name. They share one calculation engine and one set of documented assumptions, so numbers carry across between them without contradiction.

Working out what an investment becomes

Start here if you know what you can invest and want to know where it lands.

Working backwards from a goal

Start here if you know the number you need and want to know what it takes to get there.

Measuring a return you have already earned

These are backward-looking. Use XIRR for anything with more than one payment date.

Comparing against the alternatives

The instruments people weigh a SIP against, on the same terms, so the comparison is like-for-like.

What every calculator here has in common

  • One engine. All nineteen call the same tested functions, so a figure from the goal planner fed into the SIP calculator reproduces exactly.
  • Documented assumptions. Every timing and compounding convention is written out on the methodology page, so you can find why another calculator disagrees.
  • A year-by-year table on every page. Not just a total — the whole path, so you can see when compounding actually starts doing the work.
  • Works without JavaScript. Default figures, chart and table are all in the static HTML.
  • Nine currencies, with proper lakh and crore grouping for rupees, remembered between visits.
  • Shareable links that carry your inputs, so you can keep a scenario without a screenshot.
