Work out Central Civil pension from last basic pay or average emoluments, then check the PPO figure and the reduced pension after commutation.
Why do I have to enter two pay figures?
Because the rule picks the more beneficial one and the order can be wrong in either direction. A department can read the ten-month average where the last basic pay was higher, or read the last basic pay where the average was higher. This page prices both and tells you which one fits the pension line.
Why is the reduced pension smaller but Dearness Relief unchanged?
Because the official Pensioners’ Portal says the monthly pension stands reduced by the portion commuted, while Dearness Relief continues on the original pension without that reduction. The commutation cuts the pension line, not the DR base.
What if the PPO matches the reduced pension and not the basic one?
Then you are probably looking at the pension after commutation, not the original basic pension. That is a good explanation, not an error. A lot of pension papers put the two figures close together and readers lift the smaller one first because it is the number that lands in the bank.
Why does this page not compute the commuted lump sum?
Because that cash value depends on an age-based commutation factor table. The official portal names the table and links it, but this page does not quote the age factors, so it does not pretend to price the lump sum. It stays on the monthly pension line the order already prints.
Can this page check every government pension?
No. It is only for the Central Civil path the Pensioners’ Portal describes. EPS, defence pensions, state pensions and annuity products are different systems with different rules, and the whole point here is not to blur them into one fake family.
