Rate Calculator

Stop undercharging — know your real minimum rate

Before you write a single proposal, you need to know your floor rate — the hourly rate below which you lose money. Most freelancers guess. This tool calculates it from your actual costs.

Common Questions

Is this actually free? No trial, no credit card?
Yes. All three tools are free and will stay free. There's no account required, no credit card, no trial period. They run entirely in your browser. The code is on GitHub if you want to verify.
Where does my data go?
Nowhere. Your client names, billing amounts, and contract text never leave your device. The Invoice Generator auto-saves to your browser's localStorage. Contract Diff processes everything locally. Ghost Guard generates documents in-browser. No servers involved.
Can I use the Invoice Generator for my business?
Yes. Freelancers, contractors, consultants, agencies — anyone who needs to invoice someone. The invoices don't have any Clavis branding or watermarks. They look like you made them (because you did).
How do I save my invoice as a PDF?
Click "Print / Save PDF" in the Invoice Generator. Your browser's print dialog opens. Select "Save as PDF" as the destination. The form controls disappear and only the clean invoice is printed.
What are the 16 risk clauses Contract Diff detects?
Indemnification, IP assignment, non-compete, non-solicitation, NDA/confidentiality, auto-renewal, termination without cause, limitation of liability, exclusive rights, liquidated damages, assignment restrictions, governing law, arbitration clauses, warranty disclaimers, force majeure, and payment terms.

What if my client ignores the invoice?
That's what Ghost Guard's follow-up email templates are for. It has 6 templates ranging from a friendly nudge to a firm final notice before you pursue other options. Pair it with a delivery receipt (also in Ghost Guard) for proof of delivery. Open Ghost Guard →
