When this estimate can be misleading
- This is a like-for-like time conversion, not a market salary benchmark.
- Benefits and paid leave may not scale directly with hours.
- The result cannot determine whether an offer is fair or compliant.
- Use target pay as the annual salary that preserves the current implied hourly rate.
