Child Support Calculator

Our child support calculator is used to determine child support payments. Child support payments are determined based on the parents’ incomes, the number of children, and which parent the children live with. Our child support calculator only includes the basic child support payment, and not any special or extraordinary expenses. Calculating child support payments can be difficult, and it is important that the public have access to accurate child support calculations. We developed our free child support payment calculator to provide an easy way to calculate child support in British Columbia.

Spousal Support Calculator/Alimony Calculator

Our spousal support calculator (sometimes called a spousal maintenance calculator or divorce alimony calculator) is used to determine spousal support payments. Spousal support payments are determined based on the incomes of both parties and the length of the relationship. If spousal support and child support payments are being calculated, then the number of children, the ages of the children, and who the children live with also affect the spousal support payment.
