Child Aupport Calculator

Raising children requires emotional, financial, and practical support from both parents, regardless of their relationship status. When parents separate or divorce, child support arrangements help ensure children’s needs are met. However, figuring out how much child support should be paid can be confusing. That’s where our Child Support Calculator comes in handy.

This simple, online calculator helps parents estimate their monthly child support obligations. By entering basic details such as each parent’s income, number of children, and custody share, you can quickly get an approximate calculation of who should pay and how much.

How to Use the Child Support Calculator

Our calculator is user-friendly and requires only a few steps:

  1. Enter Parent 1’s Monthly Income
    Input the monthly income of the first parent in dollars.
  2. Enter Parent 2’s Monthly Income
    Provide the monthly income of the second parent.
  3. Input the Number of Children
    Enter how many children are covered under the support arrangement.
  4. Enter Custody Share of Parent 1 (%)
    Add the percentage of custody time that Parent 1 has (between 0–100%). The calculator automatically adjusts Parent 2’s share.
  5. Click “Calculate”
    The tool will process your inputs and display:
    • The total combined household income
    • The base support obligation per child
    • Which parent is responsible for paying
    • The estimated monthly support payment
  6. Click “Reset” to Start Over
    If you want to calculate again with different numbers, use the reset button.

Example: How the Calculator Works

Let’s look at a real-life scenario:

  • Parent 1 Income: $4,000/month
  • Parent 2 Income: $2,000/month
  • Number of Children: 2
  • Custody Share (Parent 1): 60%

Step 1: Total Income
$4,000 + $2,000 = $6,000

Step 2: Base Support Obligation
2 children × $500 each = $1,000/month

Step 3: Share of Obligation

  • Parent 1 (earning ⅔ of income) owes $666.67
  • Parent 2 (earning ⅓ of income) owes $333.33

Step 4: Custody Adjustment

  • Parent 1 covers more custody time, reducing their obligation.
  • Parent 2 has less custody, increasing their payment responsibility.

Final Result: Parent 2 should pay $333.34 per month in child support.

This example shows how income and custody balance influence who pays and how much.

If you want a more accurate estimate, include all monthly income sources such as salary, bonuses, or freelance work.

12. Can grandparents or guardians use this tool?
Yes, any caretaker responsible for children can use it to estimate support obligations.
