Good to know
The formula
Score = spells × spells × total days. A spell is one continuous period of absence, however long.
Why squared
Many short absences disrupt work more than one long one, so the formula weights spells heavily. 10 days in one spell scores 10; 10 days in 5 spells scores 250.
Use it carefully
Do not apply it to absence the law protects, such as maternity leave, or to disability-related or long-term illness without advice. Look at the reasons, not only the score.
Fair process
A score starts a conversation. Decide in your policy what each level means and apply it the same way to everyone.
Questions people ask
Is it free? Do I need to sign up?
Yes, it is free and you do not need to sign up. Open it and use it as often as you like.
Is my data safe?
The numbers are worked out in your browser. Nothing you type is sent to USR unless you choose to email yourself the result.
How accurate is the result?
It is an estimate based on the rules shown on this page as of November 2026, not legal or tax advice. Rules and rates change, so check with your CA before you act.
Is the Bradford factor a legal rule?
No. It is a common scoring method. Your policy decides what each score means, and protected absence must be treated separately.
Is my data saved?
No. Everything stays in your browser. Use first names or codes for privacy.
