1. It starts with your roster, not your bank statement
Your pay is a function of what you flew: report and release times, sector count, overnight nights, and any leave or standby days in the month. A pay calculator needs your full roster imported first, see roster sync, so it has the same data payroll is working from.
2. Duty pay is calculated report-to-release
Most crew assume duty pay is block hours. It isn't. It runs from your report time to your release time, so boarding delays, ground time between sectors, and post-flight duties all count toward the hours your airline's rate is applied to.
3. Overnight allowance and per diem are separate calculations
Overnight allowance pays per night away from base. Per diem pays per hour away from base. Airlines that pay both apply different rates and different taxable splits to each, see our crew per diem guide for the full breakdown.
4. Premiums and bonuses need their own line
Late finishes, early starts, public holiday duties, and seniority-based premiums all attach to specific duties. A calculator that just totals hours misses these, a proper breakdown lists them line by line so you can see what's driving the total.
5. Compare the total, then drill into line items
When your payslip arrives, check the headline total first. If it's off, work down through duty pay, overnights, per diem, and premiums individually. Most discrepancies trace back to one missed overnight or one wrong sector count, not a systemic error.
6. Layvr builds this automatically from your import
The Layvr pay calculator reads your imported roster and produces this breakdown without manual entry. The payslip checker then compares it line by line against your actual payslip PDF.
