Frequently asked questions
Is the widget free?
Yes — completely free, no sign-up, no limits. The widget shows a small "Child Support Calculator by SupportSum" credit link below the tool, which is how we keep it free.
Will it slow down my website?
No. The calculator loads in a lightweight iframe with lazy loading, so it runs independently and never blocks your own content from rendering.
Can I lock it to my state?
Yes. Pick your state in the builder to generate a state-specific version — ideal if you serve clients in one state. Or leave it on "all states" so every visitor can choose their own.
Do I have to keep it updated?
No. Paste it once. The calculator always reflects the latest verified state guidelines from SupportSum, so it stays current with no work on your end.
