Overview
Natural language math
Type "15% off 80" or "200 + 8% tax" — LetsCalc parses intent and calculates instantly without memorizing formulas.
Text + numbers
Mix labels and math on the same line; use "//" for comments and "#" for headers to organize budgets and notes.
Currency & units
Calculate in mixed currencies like "50 USD + 30 EUR in GBP" or convert "100 km in miles" — 150+ currencies with offline support.
Variables & live updates
Define variables such as "Rate = 50" and reference them later; change one value and the whole worksheet recalculates.
Power-user shortcuts
Type "5k" for 5,000, "sum" to total lines above, and "prev" to carry the last result into a new line.
Focus-first design
Clean interface with dark mode support and no account required — calculate at the speed of thought.
