401k Contribution Calculator
This works out what to set on the payroll page rather than projecting a balance to retirement. One tab takes your salary, how often you are paid, your age at the end of the year and what you have already deferred, and returns the dollars per paycheck and the deferral percentage that reach the annual limit with the paychecks you have left, along with the employer match that earns. The other takes your pay, your age and the employer contributions and works out how much you are allowed to put in at all, including the age 50 catch-up, the higher band for ages 60 to 63 and the ceiling on everything going into the account. Every IRS limit is an input here, because all of them are reindexed each year.
