About EVMath
EVMath is a free set of electric-vehicle calculators and model guides built to answer one question honestly: what will an EV actually cost you to own, charge, and drive? No dealership spin, no lead forms — just the math, with the assumptions shown.

Who runs EVMath
EVMath is built and maintained by Pond Software, a small independent studio that makes free, ad-supported calculator sites — including DebtMath, Compound Interest Calculator, and a mortgage calculator. The same idea runs through all of them: take a decision people normally make on gut feel or a salesperson's pitch, and turn it into a transparent calculation you can check yourself.
We're not a dealer, a manufacturer, an automotive marketplace, or a charging network. Nobody pays us to rank their car higher, and there are no sponsored placements in our calculators or guides.
Why we built it
The numbers that decide whether an EV makes sense — the federal tax credit, your local electricity rate, real-world range, charging time, depreciation, and total cost versus a gas car — are scattered across IRS pages, utility bills, and spec sheets, and most of them are easy to get wrong. Manufacturers quote best-case range; dealers quote best-case financing; nobody puts it all in one place with your inputs.
EVMath does. Every tool lets you plug in your own miles, rates, and vehicle, and shows the working so you can see exactly how a result was reached. Start with the EV vs. gas total-cost-of-ownership calculator or the EV tax credit calculator, and browse the full lineup on the calculators page.
Where our numbers come from
Vehicle specs — EPA range, battery capacity, charging speed, and MSRP — come from manufacturer spec sheets and fueleconomy.gov. Federal tax-credit rules and eligibility follow IRS guidance for the stated year. Electricity and gasoline prices use published state and national averages, which you can override with your own rates in any calculator. We link to these sources on the pages that rely on them so you can verify — and so future updates know exactly what to re-check.
When a figure can't be verified from a real source, we leave it out rather than estimate. You won't find invented statistics or made-up prices on EVMath.
How we keep it current
EV tax credits and vehicle specs change every year, and stale incentive data is worse than none. We date-stamp our guides, keep the 2026 tax-credit page aligned with current IRS rules, and refresh model data as new model-years and pricing land. If you spot something out of date or wrong, tell us — see the contact page.
EVMath is free to use, supported by advertising and a small number of affiliate links. How that works — and what it means for your privacy — is spelled out in our privacy policy and affiliate disclosure. Our tools are educational estimates, not financial advice — see the terms of use.
