Choose the result you need
Use the simple calculator for everyday sums, the scientific calculator for powers and trigonometry, or the fraction calculator when you want to keep a result in fraction form. Check the selected angle mode before comparing a trigonometric result.
Compare prices using the right inputs
A discount changes the price; tax and tips are separate steps. Use the discount, tax or bill-split tool for the amount you actually want to check. Enter the rate that applies to your case. Currency conversions use reference rates, so a bank or payment provider’s final quote can differ.
Check an overnight shift
If a shift crosses midnight, do not simply subtract the two clock times. The work-hours calculator accounts for an overnight shift and lets you subtract breaks. Compare the total with your actual shift and your workplace’s timesheet rules.
