Unpaid Overtime Annual Value
Calculate the annual value of unpaid extra hours and the effective hourly-rate erosion.
What this means
The calculator compares contracted hourly rate with the effective rate after unpaid overtime.
Formula used
Unpaid value = extra hours per year x contracted hourly rate.
Worked example
£40,000, 37.5h/week, 5 extra hours, and 46 working weeks gives about £5,333.33 of unpaid value.
Common questions
Can I use this internationally?
Yes. Currency selectors are display-only unless a tool explicitly says otherwise; no currency conversion is performed.
How exact is the result?
It follows the published Technofatty formula for this tool, but real life can add fees, rules, timing quirks, and context.
Plain-English summary
A few extra hours can become a surprisingly formal-looking pile of money.
This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
