About

About Dear Calculator

Dear Calculator is being built as a clear, practical calculator directory for a global audience. The goal is simple: make useful calculations easy to find, understand, and complete in one clean place.

What we are building

The current collection includes 2078 calculator pages across 30 categories, with 2078 calculators usable now. The site is structured so new calculators can be added without redesigning the whole system.

Our approach

Dear Calculator prioritizes speed, mobile-friendly layouts, useful explanations, copy/export workflows, related calculators, and focused pages. Calculators are designed to run locally in the browser where possible.

Monetization

The site may use non-intrusive advertising in the future to keep calculators free. Membership features are not the current focus.
