What Bare is
Bare is a small set of single-purpose calculators. Each page does one job in your browser: fees, payoff math, unit conversion, or a construction quantity. No account, no feed, no blog.
Math stays on the page. When a tool uses published rates (IRS mileage, processor fees), those defaults live in a rates file and are labeled as estimates — confirm with the source before you file or price a product.
This site is not tax, legal, lending, or medical advice. YMYL topics get honest formulas and clear “what this is not” copy, not guarantees.
