Verified Logic & Data
Every formula used in our finance and health calculators is cross-referenced against established academic and financial standards. From the Amortization Schedules in our loan tools to the Mifflin-St Jeor Equation used for BMR, we prioritize mathematical integrity above all else. Our team regularly audits the codebase to ensure edge cases (like zero interest or leap years) are handled with precision.
