How the Slovenia neto plača calculator is verified
Inputs

| Bruto plača / leto (EUR) | grossAnnual | 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) |
|---|---|---|
| Prispevki (22,10%) | contrib | $round(grossAnnual * $const.contribRate, 2) |
| Davčna osnova | taxBase | ($b := grossAnnual - contrib - $const.allowance; $round($b > 0 ? $b : 0, 2)) |
| Dohodnina | pit | ($t := taxBase; $round((($t < $const.b1 ? $t : $const.b1) * 0.16) + (($t > $const.b1 ? (($t < $const.b2 ? $t : $const.b2) - $const.b1) : 0) * 0.26) + (($t > $const.b2 ? (($t < $const.b3 ? $t : $const.b3) - $const.b2) : 0) * 0.33) + (($t > $const.b3 ? (($t < $const.b4 ? $t : $const.b4) - $const.b3) : 0) * 0.39) + (($t > $const.b4 ? ($t - $const.b4) : 0) * 0.50), 2)) |
| Neto / leto | netAnnual | $round(grossAnnual - contrib - pit, 2) |
| Neto / mesec | netMonthly | $round(netAnnual / 12, 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 | 0.221 |
allowance | 5551.93 |
b1 | 9721.43 |
b2 | 28592.44 |
b3 | 57184.88 |
b4 | 82346.23 |
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 24,000 EUR (2,000/mo)

expect taxBase | 13144.07 |
expect pit | 2445.32 |
expect netMonthly | 1354.22 |
Case 2 — S3 60,000 EUR
given grossAnnual | 60000 |
