Show HN: Built a Free UK Child Maintenance Calculator

1•rafayexalter•51m ago
I was researching existing calculators and noticed some sites either made the process unnecessarily confusing or locked downloadable reports/PDFs behind a paywall.

So I built a simpler version that’s completely free to use.

Still early, only a couple of calculators/tools are live right now, but I’m planning to add many more over time.

Suggestions are welcome
