Office & Work Calculators

About these office and work calculators

Questions about pay, leave and notice come up at every job, and the answers are rarely printed anywhere handy. These calculators cover the common ones: converting a salary between hourly, weekly and yearly, working out pro-rata annual leave, counting working days between two dates, finding the end of a probation period, and estimating UK statutory redundancy pay.

They give you a quick, honest estimate, not legal or financial advice. Employment rules differ by country and by contract, and statutory figures such as the weekly pay cap for redundancy change from time to time, so check your contract and the current guidance on GOV.UK or with ACAS before you rely on a number for a real decision. Everything is worked out in your browser and nothing you enter is stored.
