Free Calculators for Americans

These tools cover the calculations Americans use every day — from splitting a restaurant check to running mortgage payment scenarios or checking if your BMI is in the healthy range.

Tip Calculator (15–20% US Standard)

The standard tip in the US is 15–20% for sit-down restaurants, 10% for buffets, and 10–15% for delivery. The tip calculator lets you enter the bill, choose your tip percentage, and instantly splits the total among any number of people — no mental math needed.

Mortgage Calculator

Use the loan calculator for any US mortgage: enter the loan amount, your annual rate, and the term (typically 15 or 30 years). It shows monthly payment and the full amortization schedule. Note: result covers principal + interest only — taxes, insurance, and PMI are not included.

Imperial ↔ Metric Unit Converter

The unit converter handles the conversions Americans need most: miles ↔ km, pounds ↔ kilograms, Fahrenheit ↔ Celsius, feet/inches ↔ meters, and gallons ↔ liters. Useful for international recipes, travel, or medical forms.
