Goal-Based SIP Calculator

This works backwards from the regular SIP formula — instead of telling you what a fixed monthly amount grows into, it solves for the monthly amount that grows into your target by the deadline you set, given your expected return rate.

A higher assumed return rate lowers the required monthly SIP, but returns aren't guaranteed — it's worth checking the required amount at a more conservative rate too, so your goal doesn't depend entirely on optimistic market assumptions.
