Beautician Salary Formula: Base + Performance Bonus + Per-Execution + Overtime

Why salary formula transparency matters

Salary disputes are a top-3 reason for beautician turnover. Transparent formulas aren't just compliance — they're organisational health. This article walks through a beautician's NT$38,500 monthly salary, decomposing the 4 independent components and pointing out common owner mistakes.

Component 1: Base salary

Formula: **Base = monthly wage × (days present / total working days)**. Example: monthly wage NT$30,000, May has 22 working days (excluding Sundays + holidays), employee present 20 days → base = NT$30,000 × (20/22) = NT$27,272. ⚠️ **Common mistake**: using daily rate = wage/30 × days present means full-attendance employees can't reach their full monthly wage (a month never has 30 working days). MeiYe Zhan v1.2.0+ uses wage/totalWeekdays for accuracy.

Component 2: Performance bonus (commission)

Formula: **Performance bonus = revenue × commission %**. Commission is usually 4 tiers (higher revenue = higher %): < NT$50,000 = 15%, NT$50,000–100,000 = 18%, NT$100,000–150,000 = 22%, > NT$150,000 = 25%. Example: monthly revenue NT$60,000 → bonus = NT$60,000 × 18% = NT$10,800. ⚠️ **Common mistake**: including vouchers, legacy debt collections, refunds in the revenue base → inflated revenue, over-commission, shop loses margin. The fix: exclude these three at the source (MeiYe Zhan v1.0.38+ routes all performance through `isPerformanceEligible` helper).

Component 3: Per-execution bonus

Formula: **Per-execution bonus = Σ fixed bonus per qualifying service**. Independent from commission, this is a separate incentive for specific actions. Example: NT$100 per treatment upgrade, 8 upgrades this month → per-execution bonus = NT$800. ⚠️ **Common mistake**: combining per-execution with performance and then applying commission % → double-counting. MeiYe Zhan v1.2.5 explicitly separates: dashboard "revenue" excludes per-execution; payroll page sums each independently.

Component 4: Overtime

Formula (Taiwan Labor Standards Act): **Overtime = hours × hourly rate × 1.34**. Hourly rate = monthly wage / (working days × 8 hours). Example: wage NT$30,000, working days 22 → hourly rate = NT$30,000 / 176 = NT$170. 5 overtime hours → overtime = 5 × NT$170 × 1.34 = NT$1,139. ⚠️ **Common mistake**: using 1.0× (no 1.34 multiplier) → violates labor law and triggers staff protest.

Component 5: Leave deduction (v1.2.0+)

Taiwan labor law treats leave types differently: **Sick leave** = wage/30 × 0.5/day (half pay). **Personal leave** = wage/30/day (full deduction). **Annual / scheduled / public holiday / bereavement** = no deduction. Example: NT$30,000 wage, 1 sick day → deduction = NT$30,000 / 30 × 0.5 = NT$500. ⚠️ **Common mistake (bug fixed in v1.2.1)**: annual / scheduled / public holiday shouldn't deduct salary, but if base formula uses "daily rate × days present", it auto-deducts unworked days → double deduction. MeiYe Zhan uses `leaveSalaryAddBack` to neutralise this.

Transparency design

MeiYe Zhan v1.2.2+ attendance payroll page displays the full formula: each employee's salary composition expandable to "base formula + bonus formula + per-execution formula + overtime formula + per-leave-type deduction details". Employees can verify their own; owners can verify line by line; disputes drop sharply.
