How Our Calculations Work
Our methodology is built on transparency and practical accuracy. We develop each tool by studying official documentation, consulting local regulations (such as AFIP rules in Argentina or LFT in Mexico), and applying industry-standard mathematics. Our review team updates the parameters when tax rates, salary brackets, or formulas change. We clearly display when results are exact values and when they should be interpreted as informative screening estimates or financial projections for general use.
Clear formulas
We use transparent formulas you can understand and verify.
Official sources when available
We base calculations on official and reliable sources.
Useful explanations
Each tool includes helpful notes and examples.
Results shown as estimates
When values can vary, we show results as estimates.
We are committed to transparency. If you spot an error or a regulatory update we missed, please let us know.
