How we built these
Every calculator publishes inputs, formulas and outputs on the page itself. The numbers are run client-side, in your browser. Nothing you type is transmitted to a server, and no account is required.
When a calculator makes an assumption, the assumption is named in plain English above the result. When a result has limits, the limits are listed below it. No invented benchmarks, no fake reviews.
After you have the numbers, jump to the builder or templates to design the card.
