How to use this tool

  1. Enter likely sale prices before and after the proposed restoration, labor hours, and your target hourly earnings.
  2. Open optional costs to include materials, specialist work, selling fees, and a contingency.
  3. Use net value added and maximum hours to decide whether to proceed, simplify, or stop the work.

How the result works

The calculator compares estimated proceeds after selling fees, subtracts restoration expenses and a contingency, then divides the value available for labor by time spent.

Restoration can reduce value if it removes original finishes, changes parts, or is not professionally appropriate. Do not treat the result as an appraisal or a guarantee of resale price.

Frequently asked questions

What is net value added?
It is estimated restored-sale proceeds minus as-is proceeds and additional restoration expenses after the same selling-fee assumption.
Why use a contingency?
Unexpected parts, repair time, and specialist work often increase costs. The percentage lets you reserve a margin for overruns.
What if restoration takes zero hours?
The calculator shows the value-added amount but does not invent an hourly return. Enter a realistic labor estimate for the hourly comparison.
Should I restore every antique before selling?
No. Some buyers prefer untouched condition, and repairs may damage provenance or originality. Compare the financial case with conservation risk.
Does this estimate include tax?
No tax treatment is inferred. Add relevant tax, insurance, storage, and other costs into your own decision process.
