About TickCalc

TickCalc is a set of free calculators for the arithmetic people do at work and around the house: hours worked and time cards, overtime pay, PTO accrual, salary-to-hourly conversion, dates and business days, percentages, tips, tire sizes and trip fuel cost.

Every calculator runs in your browser, so nothing you enter is sent anywhere, and every page shows the formula and the assumptions behind the result. Where US rules matter, such as overtime at one and a half times the regular rate after 40 hours in a week or federal holidays in business-day counts, the page says what is assumed so you can check it against your own employer or state.
