Field notes
The calculator asks for each partner’s taxable income and the number of children under three at the start of the year, then shows annual and monthly differences alongside a break-even share. Its seven examples include both one-earner households and more evenly split incomes. The page says results are calculated on the user’s device, but excludes tax credits, cross-border rules, and rounding by the tax office. Its figures are based on a bill that the page says had not yet appeared in the Journal officiel.
