This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.
How this is calculated
Work backwards. Whatever you already have grows on its own, so subtract that from the target first, then find the level monthly amount whose accumulated value covers the rest. Over three years at a deposit rate the growth is a small share of the total, which is worth seeing: for short goals the return assumption barely matters and the discipline does.

What it assumes
- Contributions at the end of each month, and a constant return.
What it deliberately does not model
- Inflation is not applied, so a distant target in today’s money will cost more by the time it arrives.
- Tax on the returns is not deducted.

Frequently asked questions
- Why does the return matter so little?
- Over a short horizon most of the money has only been invested for a few months. Growth compounds with time, so on a three-year goal it is a rounding item and on a twenty-year one it is most of the answer.
