About These Tools

From a full scientific calculator with trigonometry and logarithms to quick everyday tools like tip splitting, BMI, and loan amortization, ToolsPix calculators are designed to give you accurate answers in seconds. Every calculator runs locally in your browser โ€” there is no data collection and no account required.

The financial calculators โ€” loan, discount, percentage, and currency converter โ€” are built for practical decisions rather than academic exercises. The loan calculator, for example, produces a full month-by-month amortization schedule so you can see exactly how much interest you pay over the life of a loan at any interest rate.

The health tools (BMI calculator) and productivity tools (Pomodoro timer, invoice generator) round out a collection that covers everything from a quick bill split at a restaurant to a detailed mortgage comparison.
