Our Methodology
Formula Verification
We research and implement formulas from authoritative financial textbooks and regulatory sources. Each formula is tested against multiple verification sources before deployment.
Edge Case Testing
We test calculators with extreme values and unusual scenarios to ensure they handle all inputs correctly. This includes zero values, negative numbers, and maximum limits.
Cross-Validation
Results are compared against established financial tools and manual calculations. We validate that our results match industry standards within acceptable rounding margins.
Continuous Updates
We monitor regulatory changes, tax law updates, and contribution limit adjustments. Calculators are updated promptly when official figures change.
