Treat the labels as descriptions, not legal classifications
A Global comparison cannot infer part-time status, benefit eligibility or employment protections from weekly hours. Enter what each real package offers and check the applicable local rules outside this calculation.
Do not proportionally scale every field from the full-time role. A part-time offer can keep some benefits, remove others, change commute frequency and carry costs that do not fall with hours.
- Base and variable pay for each package
- Benefits valued separately for each package
- Paid hours, recurring unpaid hours and weeks per year
- Commute time, commute days and direct work costs
Worked example: two independently entered packages
| Measure | Full-time | Part-time |
|---|---|---|
| Base and variable pay | 80,000 + 4,000 | 48,000 + 0 |
| Entered benefits | 8,000 | 4,000 |
| Direct annual work costs | 3,000 | 2,000 |
| Paid plus unpaid weekly hours | 40 + 2 | 24 + 1 |
| Commute pattern | 45 min × 4 days | 45 min × 3 days |
| Annual committed hours | 2,160 | 1,308 |
| Net annual work value | 89,000 | 50,000 |
| Part-time difference | — | -39,000/year; -2.98/hour |
Interpret annual value, hourly value and parity separately
The annual difference measures compensation and entered benefits after direct costs. The hourly difference also reflects each schedule’s unpaid and commute time. A shorter schedule can therefore narrow the hourly gap without closing the annual gap.
With all other part-time inputs held fixed, 51,894.44 of part-time base pay would match the full-time role’s effective hourly value. That is an hourly-parity threshold, not the salary needed to match 89,000 of annual value.
Review schedule quality outside the arithmetic
The tool does not price flexibility, career progression or schedule stability. It also applies no tax or statutory-benefit rule. Those considerations belong beside, not hidden inside, the numeric result.
- Whether hours are predictable or can expand without pay
- Control over days, shifts and availability
- Continuity of benefits and progression opportunities
- Childcare, caring, study or recovery constraints
- Applicable local benefit and part-time protection rules
