About FeeKit
High-precision, privacy-first financial calculation utilities engineered for US merchants, UK businesses, independent contractors, and digital sellers.
Free, Private Financial Precision for the Modern Economy
Launched in September 2026, FeeKit is a specialized financial computation platform offering over 199+ free calculators. We serve independent freelancers, e-commerce store operators, digital service agencies, and small business owners across the United States and the United Kingdom who need exact mathematical certainty without the bloat, cost, or complexity of traditional enterprise software.
FeeKit was built to solve a simple but critical problem: standard business calculators are frequently cluttered with intrusive popups, gatekeep basic formulas behind monthly subscriptions, and upload proprietary sales figures to unknown third-party servers. In contrast, FeeKit operates on a strict 100% client-side privacy model—every formula executes locally in your browser, your financial data never touches an external server, and all tools remain free forever with no account creation or credit card required.
FeeKit is a product of Snab Innovations, an independent software studio based in India dedicated to engineering fast, robust, and accessible digital utilities for global creators and businesses.

All calculators are manually verified against official IRS, HMRC, and payment gateway documentation.
Our Mission
“FeeKit exists to give every freelancer, merchant, and small business owner the same financial precision tools that enterprise businesses take for granted — completely free, completely private, and always up to date.”
Every calculation runs directly in the user browser via pure TypeScript. Your private calculation values are never stored on our servers.
No subscriptions, no trials, no paywalls. We believe essential math for small business survival should be accessible to everyone.
Forward and reverse payout math gives operators total pricing confidence, protecting margins against hidden gateway cuts and district surtaxes.
How We Keep Rates Accurate
Because FeeKit covers financial planning, sales tax compliance, and merchant economics (YMYL topics), we hold our math to rigorous verification protocols:
- Direct Official Source Calibration
Rates are verified against primary statutory documents: official IRS Form 1040 Schedule SE tax guidelines, UK HMRC Notice 700 VAT schedules, California CDTFA, Texas Comptroller, and published Stripe, PayPal, Square, and Wise merchant pricing schedules.
- Immediate Revision on Gateway or Regulatory Changes
When payment processors adjust cross-border surcharges or states amend municipal sales tax thresholds, our mathematical matrices are patched and deployed to production within 24 to 48 hours.
- Transparent Methodology Documentation
Every formula, rounding rule, and deduction tier is openly documented on our Methodology & Calculation Standards page so users can inspect the underlying arithmetic.
- Peer-Reviewed Mathematical Testing
All financial calculation engines undergo automated unit tests and peer review against real-world transaction statements prior to release.
Corporate Entity & Governance
FeeKit is designed, engineered, and maintained by Snab Innovations, an independent digital products studio based in Nashik, Maharashtra, India.
