Behind the Numbers

Calculation Methodology

Every result you see follows a four-step process — from official source to your screen.

Source the Official Rule

We start from the primary source — the Finance Act, RBI circular, or scheme notification — to get the exact formula.

Build the Calculation

The formula is implemented in code with the same slab boundaries, rounding rules, and exemptions the law specifies.

Cross-Check with Examples

We verify each calculator against official sample calculations and edge cases like rebate limits and surcharge thresholds.

Publish and Monitor

After publication, we track regulatory changes and update the calculator the moment a new rule takes effect.
