Understanding the Calculator Inputs
Gross Weekly Income
Gross weekly income refers to your earnings before taxes and other deductions.
This generally includes:
- Salary
- Wages
- Overtime
- Bonuses (where applicable)
- Certain additional income sources
Higher weekly income generally results in a higher estimated child support payment.
Number of Qualifying Children
The payment percentage changes according to how many children qualify.
Generally:
- One child requires a lower percentage.
- Multiple children increase the estimated payment percentage.
Shared Care Nights
Shared care represents the number of overnight stays with the paying parent each year.
As shared care increases, the estimated child support payment may decrease.
CSA Payment Formula Explained
The calculator estimates child support using a simple percentage-based approach.
Step 1
Calculate the payment percentage based on the number of qualifying children.
Example percentages:
- 1 child = 12%
- 2 children = 16%
- 3 children = 19%
- 4 or more children = 22%
Formula:
Weekly Payment = Gross Weekly Income × Applicable Percentage
Step 2
Determine whether shared care reduction applies.
Reduction percentages depend on annual overnight stays.
Step 3
Reduce the weekly payment accordingly.
Formula:
Adjusted Weekly Payment = Weekly Payment × (1 − Shared Care Reduction)
Step 4
Estimate the monthly payment.
Formula:
Monthly Payment = Weekly Payment × 52 ÷ 12
This converts weekly payments into an estimated monthly amount.
Example Calculation
Let’s look at a practical example.
Information
- Gross Weekly Income: $1,000
- Children: 2
- Shared Care Nights: 120
Step 1
Applicable percentage:
16%
Weekly payment before reduction:
$1,000 × 16%
= $160
Step 2
120 shared care nights qualify for approximately a 28.57% reduction.
Reduction amount:
$160 × 28.57%
≈ $45.71
Step 3
Adjusted weekly payment:
$160 − $45.71
≈ $114.29
Step 4
Estimated monthly payment:
$114.29 × 52 ÷ 12
≈ $495.26
Example Without Shared Care
Suppose:
- Weekly Income: $800
- One Child
- Shared Care Nights: 0
Weekly payment:
$800 × 12%
= $96
Monthly estimate:
$96 × 52 ÷ 12
≈ $416
Since there are no shared care nights, no reduction is applied.
Shared Care Reduction Explained
One of the most important features of this calculator is shared care adjustment.
Generally, more overnight stays reduce the estimated payment.
Typical reductions include:
| Shared Care Nights | Estimated Reduction |
|---|---|
| 0–51 | 0% |
| 52–103 | 14.29% |
| 104–155 | 28.57% |
| 156–174 | 42.86% |
| 175+ | 50% |
These percentages help estimate how parenting time may affect child support.

Why Shared Care Matters

Understanding this relationship helps parents plan finances more realistically.
