How it works
Pay is assumed to scale with the days you work. Add what each extra day costs you, such as childcare or commuting, and weeks worked for that extra day. The result is the real yearly gain, and what you keep for each extra day.
See how much of the pay for an extra working day you actually keep after tax, childcare and travel costs.
