How the Latvia alga uz rokas calculator is verified
Inputs
| Input | Field | Type |
|---|---|---|
| Bruto alga / mēnesī (EUR) | grossMonthly | number |
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 value | Field | Formula (JSONata) |
|---|---|---|
| VSAOI (10,5%) | social | $round(grossMonthly * $const.socialRate, 2) |
| Ar nodokli apliekamā | taxBase | ($b := grossMonthly - social - $const.nonTaxableMin; $round($b > 0 ? $b : 0, 2)) |
| IIN (25,5%) | pit | $round(taxBase * $const.pitRate, 2) |
| Uz rokas / mēnesī | netMonthly | $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.
| Constant | Value |
|---|---|
socialRate | 0.105 |
pitRate | 0.255 |
nonTaxableMin | 550 |
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.
