How the Argentina sueldo neto calculator is verified
Inputs
| Input | Field | Type |
|---|---|---|
| Sueldo bruto / mes (ARS) | 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) |
|---|---|---|
| Aportes (17%) | contributions | $round(grossMonthly * $const.contribRate, 2) |
| Ganancias Base | gananciasBase | ($b := grossMonthly - contributions - $const.deduction; $round($b > 0 ? $b : 0, 2)) |
| Ganancias (simplificado) | ganancias | $round(gananciasBase * $const.gananciasRate, 2) |
| Neto / mes | netMonthly | $round(grossMonthly - contributions - ganancias, 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 |
|---|---|
contribRate | 0.17 |
deduction | 2699772.83 |
gananciasRate | 0.2 |
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.
