Built for people who want real answers.

Most nutrition and fitness calculator sites are cluttered with ads, require you to create an account just to see a number, or give you results so generic they are barely useful. We built ForgeYourFit because we believe the information you need to make smart health decisions should be free and fast to access.

Every calculator on this site uses validated formulas and official restaurant nutrition data. We update our data regularly and clearly state where our numbers come from so you can trust what you see.

We currently offer ten free calculators covering fitness and restaurant nutrition. More are being added regularly. Our goal is to be the most comprehensive and accurate free calculator resource for health-conscious people in the US and UK.

Restaurant nutrition data is sourced from official brand nutrition PDFs and websites, updated for 2026. Fitness calculator formulas use MET values from peer-reviewed exercise science research and the standard WHO BMI formula. All values are estimates — portion sizes vary by location and preparation, and the FDA permits a 20 percent variance on published restaurant nutrition data.

We are always looking to improve. If you find an error in our data, want to suggest a new calculator, or just want to say hello, reach out at info@forgeyourfit.com or use our contact form.
