The 457(b) special catch-up lets you make up previously unused contribution room — up to double the normal limit — in the three years before your plan’s normal retirement age. You cannot combine it with the age-50 catch-up in the same year; you use whichever is larger.

How the 457(b) special catch-up election contribution calculator works

It caps the special catch-up at twice the normal annual limit and lets you contribute up to that, drawing on contribution room you left unused in prior years.

Worked example

Worked example: with normal annual contribution limit of $23,500 and total unused contributions from past years of $40,000, the 457(b) special catch-up election calculator shows special catch-up contribution of $47,000.

Normal limit: $23,500
Special maximum (2×): $47,000
Your allowed amount: $47,000
Extra you can defer: $23,500

The formula

Allowed = min(2 × normal limit, normal limit + prior unused contributions). Extra = allowed − normal limit.
