Military Retirement Calculator is a free online planning tool designed to help service members and veterans estimate retirement income and assess the civilian salary needed to meet their expenses. Users enter their rank, years of service, and retirement system to estimate monthly pension payments under the High-3 or Blended Retirement System (BRS). The calculator also includes options to account for VA disability compensation, dependents, state and federal taxes, household expenses, spouse income, and the potential effect of divorce and former-spouse benefit rules.

By combining these details, the tool provides an estimate of after-tax military retirement income, total household income, and the salary gap a second career may need to cover. It also offers a paid Retirement Worksheet for $4.99, with a printable review of pension value, state costs, VA rating changes, Survivor Benefit Plan considerations, and transition planning. A personalized plan is available as an expanded option. The site shares rate-update notifications and guidance for evaluating job offers and cost-of-living differences, and invites users to support the free calculator.
