NPS Calculator Guide: Corpus and Pension Estimate

An NPS estimate first projects a corpus and then divides it between a lump sum and an annuity purchase.

Projecting the corpus

QuickCalcy compounds monthly contributions using the selected annual return divided by twelve. Actual performance depends on contribution dates, asset mix, market returns and charges.

Understanding the split

The annuity allocation controls the share used to purchase retirement income. The remainder is shown as lump sum. Exit conditions can depend on age, corpus and current regulation, so the control remains adjustable.

Estimating pension

Gross monthly pension equals annuity corpus multiplied by the assumed annuity rate and divided by twelve. Actual income varies by provider, annuity type, survivor benefit and purchase-price return option.

Mistakes and limitations

The calculator does not replace PFRDA rules, an account statement or an authorized annuity quotation.
