A door that suits the home's architecture will read better to a buyer than the most expensive one. A carriage-house style suits a craftsman home; a contemporary door suits a modern one.

This adds the resale share you assumed to the energy savings you entered. It is a model of your inputs, not a forecast, and it leaves out costs such as financing and removal.
Several panels are damaged, warped or rusted through, the door has no insulation and you want the energy benefit, or failures keep recurring. This is our rule of thumb, not a standard.
A single panel is dented and the rest is sound, a spring needs replacing (HomeAdvisor puts springs at $180 to $350, an opener at $100 to $500), or the opener is failing but the door itself is fine. Springs are a technician's job, never a homeowner's.
Our own rule of thumb, not a manufacturer's or industry standard: if the repair quote is a large share of a written quote to replace the same kind of door, get the replacement quote before you authorize the repair.
Old doors collect repair costs that look small one at a time: springs, rollers, weatherstrip, a panel, an opener. Price the whole list and compare the total with a replacement quote, not just the one item that brought the technician out.
The federal opener rule, 16 CFR part 1211, applies to openers made on or after January 1, 1993. If your opener is older than that, or its safety reversal does not work, have a technician look at it before you use the door; replacing the opener may be the answer. No ROI calculation matters if the door injures someone.
