Worked example
An additional £110 take-home may become only £30 after childcare, transport and meals, changing how attractive the extra day looks.
Frequently asked questions
Should government childcare support be deducted?
Use the childcare amount you actually expect to pay after any support applicable to you.
Why include total time committed?
It lets you see the effective return for the time the extra workday removes from your personal time.
See what an additional working day contributes
Use the take-home pay attributable to the extra day, then subtract childcare, travel and other costs that arise because you work it. The calculator annualises the result using the number of extra days worked each week and the working weeks you enter.
The time-committed field helps distinguish between the paid shift and the full period that the extra workday occupies. Include routine travel or preparation if those hours are genuinely created by the decision.
Before changing your working week, consider
- funded childcare hours or other support you actually receive;
- minimum booking periods and holiday charges from providers;
- pension or benefit changes created by additional earnings;
- whether the extra day affects family logistics elsewhere in the week.
The annual net contribution shows the money left after the costs you entered. The effective return per committed hour can help compare the extra workday with other ways of increasing income.
