Contribution Calculator Instructions

1. Select what year you are planning.
2. Select your payroll agency. This will tell the calculator what your pay cycle is.
3. Select the pay period of the LES (or ELS) that you are entering information from. The calculator will assume you are looking at your most recent LES unless told otherwise.
4. Enter your Base Pay for this LES. For civilians this will be something like "Regular Pay 80 $XXXX.XX". This will prefill the "minimum" and "maximum" contributions for any given pay period. But you can change these values.
5. Change your year-end goal if it is something other than the Elective Deferral Limit. Government contributions do not count toward the Elective Deferral Limit.

That's it!

Stepping (optional):
6. Choose how many steps you want. 1 is a single "Step" (You change your contribution once during the year).
7. Move the "Step Size" slider to the left or to the right. Left will frontload your contributions, right will backload them.

Manually changing contributions (optional):
8. Using the "Contributions Table", you may manually change your contributions to any value you choose.
9. Note the shortcuts "Min/Max/Copy". Min/Max copy their respective value from "Step 3". The "Copy" shortcut will copy the contribution from the prior pay period.

Other Information

The pay date is the deciding factor of what year your TSP contributions count towards. For example, if your last pay period ends in December, but pays in January, then that TSP contribution is considered to fall in January's tax year. This calculator is programmed to account for this.

The calculator assumes your minimum contribution is 6%. You only need to contribute 5% in order to get the match. But if you plan a year-end contribution based on 5% of your current pay, and then get a raise, you will miss out on gov matching. Using 6% of your current salary will cover for step increases and promotions.

The old-school way of changing your TSP contribution is to fill out form TSP-1 and submit it to your agency. However, most federal payroll agencies (if not all), now allow you to make this change online. See below.

This calculator is free to use and print. If you subscribe to TSPcalc for $19.99/year, you can save your plan to your account for easy access.
