About this calculator
This site estimates guideline child support under Virginia law by following the same worksheets Virginia courts use. Here’s exactly how it works and where its numbers come from.

Why this site exists
I’m James, a Virginia parent of three and a chemical engineer by training. When I went through the child support process myself, I couldn’t find a tool that followed the court’s worksheet line by line and showed where every number came from, so I built one.
Each calculator here reproduces the Supreme Court of Virginia worksheet it’s based on, with the same line numbers, and every amount can be traced to Va. Code § 20-108.2. The support schedule is checked against the Code of Virginia every day. I’m not an attorney, and this site isn’t legal advice. It’s meant to help you understand the numbers before you talk to one.
Use it to explore different scenarios. For instance, if you don’t know your co-parent’s exact income, run the numbers at a few likely amounts. Save each one as a PDF (or print it) and bring them with you when you meet with your attorney. Coming in with this detail can save time and will likely save on legal fees overall.

What it follows
Each calculator reproduces a Supreme Court of Virginia child support guidelines worksheet line by line, using the same line numbers and wording:
The “?” buttons next to each entry show that line’s instructions, quoted from the form.
Where the support amounts come from
The basic support amounts come from the Schedule of Monthly Basic Child Support Obligations in Va. Code § 20-108.2(B). It covers combined monthly incomes from $0 to $42,500 for one to six children. Above $42,500, the amount at $42,500 is increased by a percentage of the excess set by the statute (2.6% for one child up to 5.0% for six).
The schedule is checked against the Code of Virginia every day. If the General Assembly changes it, the new table is reviewed before it’s published here. The date of the last check appears at the top of the calculator.
How the numbers are worked out
- Amounts entered weekly, every two weeks, twice a month or yearly are converted to monthly figures with the multipliers on the worksheets (× 4.33, × 2.167, × 2 and ÷ 12).
- Dollar amounts are rounded to the nearest dollar, with $.50 and up rounding up, as the worksheet instructions direct.
- When combined income falls between two rows of the schedule, the amount is estimated between the rows, since the statute says such amounts “shall be extrapolated.” You can switch to the next higher or lower row in the calculator’s settings.
What it doesn’t do
A guideline figure is a starting point. A court can order a different amount under Va. Code § 20-108.1(B), for example for imputed income, extraordinary medical needs or other factors, and it decides questions like how days are counted. This calculator doesn’t model those decisions.
