The decision to return to work after leave looks different once full costs are counted. 2,200 net monthly salary minus 1,400 childcare minus 200 commute = 600/month net. After 150 workwear, meals, and professional costs, often under 500/month real gain. This is not a reason to stay home — career progression, pension contributions, and mental health have their own value — but the headline salary overstates the financial gain.
A worked example
Try the defaults: expected net monthly salary of 2,200, monthly childcare of 1,400, monthly commute of 200, other work costs of 150. The tool returns 450.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Expected Net Monthly Salary, Monthly Childcare, Monthly Commute, and Other Work Costs. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
The formula behind this
Net salary minus all direct work costs. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
What the number doesn't include
Life events generate side costs: time off work, travel for guests, aftercare, lost weekends. The figure here covers the direct costs. Noting the indirect ones alongside avoids the post-event surprise.
What this doesn't capture
Life events generate side costs the figure doesn't include: time off work, lost income, travel for others, aftercare. Add 10–15% to the direct number as a buffer; the items you haven't thought of usually fill most of it.
Return to work produces a net gain figure based on the inputs provided.
