The monthly investment a goal actually requires, net of what you have already saved. The split between what you contribute and what returns supply is the useful part.
Also called: how much to invest for a goal, target corpus calculator.
₹21,520 a month for 10 years reaches ₹50,00,000. Over the period you would contribute ₹25,82,433, and returns supply the remaining ₹24,17,567.
An estimate, not an offer or a guarantee. Projected returns assume the rate you entered holds for the whole term, which no market does.
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.
Grow the existing corpus forward, subtract it from the target, and invert the annuity formula for what the remainder needs. The contribution-versus-returns split is worth looking at: over long horizons returns supply most of the total, and over short ones they supply almost none, which is why a three-year goal is a savings problem and a twenty-year goal is an investing one.

Each of these is asserted on every build. If a change to the engine ever moved one of these answers, the build would fail before the page could print it.
