A free calculator platform built for accuracy and ease of use
ForgeAPIs started with a simple observation: most online calculators are terrible. They're slow, covered in ads, use outdated data, and often require signups for basic features. We knew there had to be a better way.
Today, we're proud to serve over 100,000 users monthly with our growing suite of free calculators. From gaming currency converters that help players understand the real cost of in-game purchases, to GST calculators that save Indian businesses hours of tax calculations, to VA disability calculators that help veterans understand their benefits – every tool we build solves a real problem.
What makes us different? We obsess over accuracy. Our gaming rates are updated monthly from official sources. Our tax calculators reflect the latest regulations. Our benefits calculators use current government tables. We believe that if you're going to offer a calculator, it should give the right answer – not an approximation, not last year's rates, but the actual correct result.
No popups, no mandatory signups, no premium versions hiding the features you need
Updated monthly with official rates from game publishers, government sources, and financial institutions. We verify every formula and rate to ensure you get the right answer every time.
All calculations run instantly in your browser. No server delays, no loading screens, no waiting. Get your answer in milliseconds, not minutes.
Zero data collection on calculations. Everything runs locally in your browser. We don't track, store, or sell your information because we never see it.
Mobile-optimized and works on any device with a browser. Save to your home screen for instant access. Works offline once loaded.
No premium tiers, no paywalls, no 'free trials.' Every feature of every calculator is 100% free. We make money from ads, not from locking features.

Free calculators and growing
We were frustrated with calculator sites that were 90% ads and 10% tool. Sites that made you create an account just to calculate a tip. Tools using outdated rates giving wrong answers. So we built something better – clean, accurate calculators that respect your time and intelligence. No tricks, no dark patterns, just tools that work exactly as they should.
