How we calculate
We turn monthly pay into weekly pay (monthly pay × 12 ÷ 52). Paid weeks lose the share of pay you don't get, and unpaid weeks lose all of it. The monthly target divides the total gap by the full months left until the due date.
Example figures
The birthing parent takes home $4,000 a month and takes 16 weeks off, 6 of them at full pay. The partner takes home $3,500 and takes 4 weeks off, 2 of them at full pay. The income gap is $9,231 + $1,615 = $10,846. With 6 full months until the due date, that's $1,808 a month.
This is an estimate for planning, not financial advice. Leave rules differ by country, state and employer, so check what you're entitled to with your employer or government.
