Hi Product Hunt! 👋
I built NettoLab because Italian freelancers have a surprisingly hard time answering one basic question: how much do I actually earn? Between VAT, social contributions (INPS), withholding tax and two different tax regimes, the gap between what you invoice and what you keep is huge and most "free calculators" out there are actually lead magnets that ask for your email and push you toward paid tax services.
So I made the opposite: 15 calculators that are genuinely free. No account, no email gate, no dark patterns. Your numbers never leave the browser, and every result shows the formula and the assumptions behind it because a number you can't verify is a number you can't trust.
It's Italian-language and Italy-specific by design (tax rules don't translate!), but if you're curious about how freelance taxation works in Italy, the flat-tax calculator is a fun rabbit hole.
It's a solo project, still early. I'd love feedback especially from fellow freelancers and anyone who's built calculator/tool sites: what would make you trust a tax estimate from a free tool?
Grazie! 🇮🇹

Does the hourly rate calculator account for the actual days you'd realistically bill in a year, or does it assume full 220 working days?

@arindfxh Great question, that assumption is exactly the trap this calculator is built to avoid. 🙂
It doesn't assume a fixed 220 days. You set three things: working weeks per year (default 46, so vacation and downtime come out), hours per week (default 40), and the one most people forget: the share of time that's actually billable. Default is 50%, because admin, quotes, emails and sales eat the rest. There's also an optional safety margin (default 15%) added on top of the minimum rate.
So with defaults it plans around ~920 billable hours a year, not 1,760+. Every assumption is an editable field, and the formula is shown right next to the result so you can sanity-check it.
Curious if the 50% billable default matches your experience, that's the number I debated most when building it.
