Thrift haul buy ceiling
Replay last trip and get the most you could have paid at the register and still earned your hourly floor.
A different question than the trip calculator
The trip calculator asks whether the trip paid. This asks how much the trip could have cost. The answer is a ceiling you can carry into the next store that looks like this one.
The math
| Output | Formula |
|---|---|
| Keepers' value | keepers × expected net per keeper |
| Buy ceiling | keepers' value − (miles × cost per mile) − (hours × hourly floor) |
| Ceiling per item | buy ceiling ÷ items bought |
| Surplus | buy ceiling − register total |
| Spent on rejects (estimate) | register total × (1 − keepers ÷ items bought), assuming rejects cost the average tag |
Inputs people get wrong
Use keepers, not items bought. Rejects cost money and time but return nothing. Count listing hours with the trip; the haul isn't worth anything until it's listed.
The cost per mile box holds an example. Check the IRS standard mileage rates for the current figure.
Questions
What is a buy ceiling?
The most you can spend on a haul and still earn your hourly floor after driving and time. Spend under it and the trip pays your rate. Spend over it and you're working for less.
Why can the ceiling be zero?
If the keepers' net doesn't cover the driving and your time at your floor, no register total makes the trip pay. Change the route or the floor, not the haul.
Should I use expected or actual sale prices?
Use what sold comps support after fees and shipping. Replace them with actual sales once the items sell, and run it again.
Is this a tax calculation?
No. Mileage here is a cost of running the car. Whether you can deduct it is a separate question for your records and tax preparer.
