Why does joining later cost so much more?

Because there are fewer years for the money to compound. The corpus needed is the same either way, so every year of delay has to be made up by a larger monthly amount.

The Atal Pension Yojana contribution needed for a chosen pension, and why joining young matters so much. The contribution for the same pension roughly quadruples between joining at 18 and joining at 40.

How this is calculated

An estimate, not an offer or a guarantee. Projected returns assume the rate you entered holds for the whole term, which no market does.

Method and background

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

The scheme guarantees a fixed monthly pension from 60, so the contribution is whatever accumulates to the corpus that pension requires. Because accumulation compounds, every year of delay raises the monthly cost sharply: the same five thousand rupee pension costs several times more to secure at 40 than at 18. The figures here are indicative rather than the official chart, which is a published table; treat them as showing the shape of the relationship.

the corpus needed is the pension capitalised at the scheme rate; the contribution is the monthly amount that accumulates to it

P: Monthly pension wanted (currency)
K: Corpus needed (currency)
n: Months of contribution (months)
