Why We Built This
Every time we needed to calculate something car-related, we'd find ourselves on sketchy websites with outdated interfaces and formulas we couldn't verify.
We wanted something better. Calculators that load fast, work on your phone, and don't treat you like a click farm. Tools built by people who actually wrench on cars and understand what matters.
Each calculator on CarMath is built with care. We research the underlying math, document our methodology, and test with real-world scenarios. If a formula has multiple variations (like quarter-mile predictions), we tell you which one we're using and why.
We're not trying to sell you anything. No affiliate links, no sponsored content, no "recommended products" shoved in your face. Just useful tools.
Who's Behind This
CarMath is built by car enthusiasts who got tired of the existing options. We're not a big company — just people who wanted better tools and decided to build them.
