About SAS Quick Tools

SAS Quick Tools is a small collection of free calculators for the everyday numbers people work out all the time: percentages, discounts, budgets, savings goals, ages, dates, times, units, shared bills and loan payments.

What we care about

• Clear answers. Every calculator shows the formula it used, so you can check the result yourself.
• Getting edge cases right. Leap years, overnight shifts, leftover cents and zero-interest loans are handled properly.
• Privacy. Calculator inputs are processed in your browser and are not sent to our servers.
• Many currencies. Money calculators work in 15 currencies.

A note on accuracy

Our results are estimates based on the numbers you enter. They are not financial, tax or legal advice. See our Terms for details.
