About OurCalculators.com
Our Mission
OurCalculators.com was built with a simple belief: when you get a number from a calculator, you deserve to understand how that number was produced. Every tool on this site shows you the formula, the variables, and a worked example — not just the result.
Why Legal Calculators?
Most calculator websites focus exclusively on finance and math, leaving a massive gap in legal calculation tools. Millions of people need to calculate South African retrenchment pay, UK redundancy entitlements, immigration points scores, personal injury settlement estimates, and inheritance tax thresholds — yet almost no mainstream calculator site serves these needs properly.
We built OurCalculators.com to fill that gap, covering 7 major legal niches across 5+ jurisdictions, alongside comprehensive finance, health, and math calculators.
Formula Transparency
Every calculator on this site includes:
- The exact formula or statutory provision used
- Variable definitions with clear explanations
- A worked numerical example
- Links to the authoritative source (BCEA, SARS, IRCC, ERA 1996, etc.)
Zero-Delay Calculations
All calculations run entirely in your browser using Vanilla JavaScript. There are no server round-trips, no data collection, and no delays. Your inputs never leave your device.
Coverage
We currently cover 30+ calculators spanning legal tools (SA, UK, USA, Canada, Australia), finance (mortgage, compound interest, FIRE, retirement), health (BMI, calorie), math (percentage), and business (ROI, AI automation ROI).
