This inverts the same compounding math a regular SIP calculator uses — instead of "how much will ₹X/month grow to?", it solves "what monthly amount grows to my target?" for your chosen rate and tenure.

Three levers move the number: a longer timeline lowers the required monthly amount (more time to compound), a higher assumed return lowers it too (higher risk), and starting with a lump sum alongside a smaller SIP reduces what the SIP alone needs to cover.

Yes — as actual returns diverge from your assumption, or your target/timeline changes, recompute periodically (e.g. annually) and adjust your SIP amount, ideally alongside a step-up.

Working backward from a goal

Most SIP calculators answer "how much will my monthly investment grow to?" This one answers the opposite, more useful question for goal planning: "how much do I need to invest monthly to reach a specific number?" — useful for a house down payment, a child's education, or a retirement corpus with a fixed target and date.

Pick a real fund

Once you have a monthly number, compare 200+ direct-growth funds on our mutual funds catalogue to find one matching your risk profile and timeline.
