The formula

Each derived value below is computed by the Valem engine from the expression shown, in this order. Nothing else runs — there is no hidden code path.

Derived valueFieldFormula (JSONata)
VSAOI (10,5%)social$round(grossMonthly * $const.socialRate, 2)
Ar nodokli apliekamātaxBase($b := grossMonthly - social - $const.nonTaxableMin; $round($b > 0 ? $b : 0, 2))
IIN (25,5%)pit$round(taxBase * $const.pitRate, 2)
Uz rokas / mēnesīnetMonthly$round(grossMonthly - social - pit, 2)

Rates and thresholds

The expressions above read these as $const. They are the figures the annual refresh replaces, so they live as data rather than being written into the formulas — which is what makes a year-on-year change a one-line diff instead of an edit to arithmetic.

Test vectors (2)

Every case is executed against this model on each build, by the Java engine and independently by a JavaScript one. A mismatch of a single cent fails the build, so the page cannot ship advertising a figure the model no longer produces.
