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) |
|---|---|---|
| Cotizaciones (~18,6%) | contributions | $round((grossMonthly < $const.contribCap ? grossMonthly : $const.contribCap) * $const.contribRate, 2) |
| Base tributable | taxable | $round(grossMonthly - contributions, 2) |
| Impuesto Único | tax | ($t := taxable; $round((($t > 877500 ? (($t < 1950000 ? $t : 1950000) - 877500) : 0) * 0.04) + (($t > 1950000 ? (($t < 3250000 ? $t : 3250000) - 1950000) : 0) * 0.08) + (($t > 3250000 ? (($t < 4550000 ? $t : 4550000) - 3250000) : 0) * 0.135) + (($t > 4550000 ? (($t < 5850000 ? $t : 5850000) - 4550000) : 0) * 0.23) + (($t > 5850000 ? (($t < 7800000 ? $t : 7800000) - 5850000) : 0) * 0.304) + (($t > 7800000 ? ($t - 7800000) : 0) * 0.35), 2)) |
| Líquido / mes | netMonthly | $round(grossMonthly - contributions - tax, 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 | 0.186 |
contribCap | 3600000 |
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.
Case 1 — S1 1,000,000 CLP — below the tax threshold
given grossMonthly | 1000000 |
|---|---|
expect contributions | 186000 |
expect taxable | 814000 |
expect tax | 0 |
expect netMonthly | 814000 |
Case 2 — S2 2,500,000 CLP
given grossMonthly | 2500000 |
|---|---|
expect contributions | 465000 |
expect taxable | 2035000 |
expect tax | 49700 |
expect netMonthly | 1985300 |
