  • Receiving Spouse Income - Annual income of the spouse who will receive support
  • Support Factor - Determined by the difference between the spouses' incomes (see table below)
  • Child Factor - Determined by the number of children (see table below)

The support factor and child factor are based on the guidelines set out in the Ontario Family Law Act.

Assumptions

This calculator makes the following assumptions:

  • The support period is for an indefinite duration.
  • The spouses are not in a common-law relationship.
  • The support is being calculated for a divorce or separation case.
  • The incomes provided are accurate and up-to-date.

Worked Example

Let's look at an example to see how the calculator works.

Suppose:

  • The paying spouse has an annual income of $80,000.
  • The receiving spouse has an annual income of $40,000.
  • There are two children.

Using the formula:

Monthly Support = ($80,000 - $40,000) × 0.25 × 0.50

Monthly Support = $40,000 × 0.25 × 0.50

Monthly Support = $500

In this example, the estimated monthly spousal support amount would be $500.
