About MilMath

MilMath is a collection of free calculators designed to help military members and veterans make sense of their finances. We believe financial planning tools should be simple, private, and accessible.

Our Calculators

• BAH Differential Calculator — Compare housing allowances between duty stations
• High-3 vs BRS Calculator — Compare retirement systems side-by-side
• VA Combined Rating Calculator — Calculate disability ratings with bilateral factor

Why We Built This

Military pay and benefits can be confusing. Official calculators exist but are often hard to find, clunky to use, or don't show side-by-side comparisons. We wanted to create something simpler.

Privacy First

We don't require accounts, don't collect personal information, and don't store your inputs. All calculations happen in your browser. Learn more about our privacy practices.

Not Affiliated with the Government

MilMath is an independent project. We're not affiliated with the Department of Defense, DFAS, VA, or any government agency. Our calculators provide estimates — always verify with official sources before making decisions.

Accuracy

We update our calculators regularly to reflect current rates and regulations. However, errors can occur. If you spot something wrong, please let us know.
