Different calculators might use slightly varying formulas, rounding techniques, or assumptions. While we aim to use the most accurate and widely accepted methods, results can differ based on these factors. To make things clearer for users, we provide detailed formulas, calculations, and explanations of how our calculator works, along with a step-by-step example.
