73.56/tfp x 100 tfp/month on reserve= $7356/ month gross. Plus $400/ month per diem. Plus 15% into your 401k is another $1103 per month. $93k year one before taxes, not including $13.2k in your 401k.
Training is year one pay at the guarantee of 87 or 89 tfp/month. Lasts through IOE, total of about 2 months.
100 tfp per month is a reasonable assumption on a pure reserve line, with a fly preference. That’s picking up nothing extra (at second year rates of $106.37/tfp). At least 15 days per month off. Working in 3 to 4 day blocks, with 3 to 4 day blocks off.
You’ll likely get BWI right out of training. LAS shortly after.
Hope that helps. Sounds like a big transition. If you do make the jump here, Welcome!
