$50 x 75 hour guarantee x 12 months = $45,000 pay based solely on Guarantee.
Per Diem is $1.85/hr TAFB (Time Away From Base). TAFB is typically between 70-80 hours for a 4-day trip. Like others have said, don’t figure per diem into your salary calculation. It’s reimbursement, not compensation.
You will rarely, if ever, fly over Guarantee on Reserve. Once you hold a Line as an FO, you will have ample opportunity to fly as much as you want. Lines range between 75 hours to 95 hours. With our pay scale, you can credit over 100 hours or as little as 65 if you choose to SAP down to the minimum.
With those facts in place, you can realistically expect a salary of between $45,000 to $60,000 before taxes, insurance, ALPA dues, 401K contributions, etc.
Hope that helps.
