4-Day vs 5-Day Week

Compare the annual pay difference with the number of workdays and hours you gain by moving from five days to four.

Worked example

If dropping one working day reduces annual take-home pay by £4,000 but gives back hundreds of hours each year, you can calculate the implied price you are paying for that free time.

Frequently asked questions

What if my employer offers four days for full pay?

Enter the same annual pay in both boxes. The calculator will show the additional time without a pay sacrifice.

Does this include commute savings?

No. Add those separately when evaluating the result; avoiding one commute each week can make the four-day option more valuable.
