Why is the monthly figure lower than the target divided by the months?

Because growth does part of the work. The gap between those two numbers is exactly what compounding contributes, and the tool prints it as its own line so you can see the size of it.

Should I use my expected return or a conservative one?

A conservative one. If you plan at twelve per cent and get nine, you arrive short at the moment you need the money. If you plan at nine and get twelve, you arrive early with a surplus, which is a far better kind of wrong.

What if the required amount is more than I can afford?

Three levers move it: a longer horizon, a smaller target, or more already invested. Extending the term is usually the most powerful, because every extra year both adds contributions and compounds the existing ones.

Does it handle a goal that is only a few years away?

It does, but the arithmetic gets unforgiving. Over three or four years growth contributes very little and the monthly figure is close to the target divided by the months, which is the honest answer for a short horizon.

About the Goal SIP Calculator

Most projections start from what you can pay and end at a number. This one runs the other way: name the amount you need and the date you need it by, and it works out the monthly commitment that gets there.

The field that changes the answer most is the one people leave blank. Anything already invested keeps growing on its own, so the monthly figure only has to cover the shortfall between the target and what that existing money becomes. Ignoring it is the commonest way these tools overstate what someone needs to save, sometimes by a wide margin — five lakh already invested at twelve per cent becomes over fifteen lakh in ten years, and fifteen lakh of a fifty lakh goal is a third of the work already done.

The output splits the answer into two parts that are worth separating: what you will pay in over the whole term, and what growth contributes on top. On a ten-year goal the split is usually somewhere near two-thirds contributions to one-third growth; stretch the same goal to twenty years and growth overtakes contributions entirely. Seeing the crossover makes the case for a longer horizon better than any argument about compounding does.

Treat the resulting figure as a floor, not a target. It is exactly right only if the return assumption is exactly right, and returns arrive unevenly. Running the calculation two or three points below your expected rate and saving that higher amount is the version of this that survives contact with a real market.

How to use it

1Enter the amount you need and the year you need it.
2Add whatever is already invested towards this goal — it changes the answer more than anything else on the form.
3Set a return you would be comfortable defending if the next five years disappoint.
4Compare what you pay in against what growth adds, then try the same goal over a longer term.
