Inputs to verify

Verify monthly contribution (₹) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify years until retirement before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify expected return (% per year) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify annuity portion (%) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify annuity return (%) before calculation; if this value uses a different unit, period or definition, convert or restate it first.

Interpreting the result

Interpretation starts with magnitude. The worked example landed at As a worked reference for “Formula of nps”,; compare yours before trusting the decimals.
