How the Chile boletas de honorarios calculator is verified
Inputs
| Input | Field | Type |
|---|---|---|
| Annual gross honorarios (CLP) | annualHonorarios | 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) |
|---|---|---|
| Retención (15.25%) | retention | $round(annualHonorarios * $const.retentionRate, 2) |
| Contribution base (80%) | contributionBase | $round(annualHonorarios * $const.contributionShare, 2) |
| Received during the year | netAfterRetention | $round($max([0, annualHonorarios - retention]), 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 |
|---|---|
retentionRate | 0.1525 |
contributionShare | 0.8 |
Test vectors (3)
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 — 24,000,000 CLP of honorarios in a year
given annualHonorarios | 24000000 |
|---|---|
expect retention | 3660000 |
expect contributionBase | 19200000 |
expect netAfterRetention | 20340000 |
Case 2 — 6,000,000 CLP — part-time
given annualHonorarios | 6000000 |
|---|---|
expect retention | 915000 |
expect contributionBase | 4800000 |
expect netAfterRetention | 5085000 |
Case 3 — 60,000,000 CLP — a well-paid consultant
given annualHonorarios | 60000000 |
|---|---|
expect retention | 9150000 |
expect contributionBase | 48000000 |
expect netAfterRetention | 50850000 |
