Evaluating military deposit decisions

Military service credit can materially improve civilian retirement outcomes, but only when the deposit strategy is evaluated carefully. This calculator helps you estimate the repayment amount and compare it with projected annuity increases. The key is to evaluate the break-even period and your planned retirement horizon before deciding.

  • Gather DD-214 and military earnings data before calculating deposit scenarios.
  • Compare total deposit cost versus expected lifetime annuity benefit increase.
  • Re-check assumptions if retirement date or service records are revised.

Frequently asked questions

Is buying back military time always beneficial?

When should I run this calculation?
