Manifesto

Calculators
should respect you.

Every other calculator site buries the answer under banners, popups, cookie walls and SEO essays. We don't. Inputs on the left, answer on the right, a single ad slot to keep the lights on.

The maths is open-source so you can audit it. The numbers are projections, never guarantees — finance is messy, but the arithmetic doesn't have to be.
