Why RateKit Exists
Too many financial tools are either buried behind paywalls, require account creation just to see a number, or are cluttered with ads and dark patterns. We built RateKit because we believe the basic math of running a business should be accessible to everyone.
Every calculator on RateKit works instantly in your browser. No data is sent to our servers. No account needed. No credit card. Just the numbers you need.
What We Build
RateKit focuses on practical tools for two main audiences:
- Freelancers & Consultants — Freelance rate calculator, Stripe/PayPal fee calculator, Self-employment tax estimator, VAT/GST calculator
- Founders & Startups — SAFE equity calculator, Burn rate & runway, LTV:CAC ratio, Break-even analysis, ROI calculator, Business loan calculator
Our Principles
