What this calculator estimates
Estimate home-office remodeling cost from room area, finishes and wiring.
How to use it
Enter Office square feet; Low cost per unit ($); High cost per unit ($); Electrical, data and built-ins ($). Select Calculate to update the results.
How the calculation works
The estimate multiplies the quantity by the low and high unit-cost assumptions, adds the fixed costs, and shows the midpoint of that range.
Worked example: starting scenario
| Office square feet | 120 |
|---|---|
| Low cost per unit ($) | 75 |
| High cost per unit ($) | 250 |
| Electrical, data and built-ins ($) | 500 |
| Estimated midpoint | $20,000.00 |
|---|---|
| Estimated range | $9,500.00 – $30,500.00 |
| Midpoint per unit | $166.67 per unit |
| Fixed/additional costs | $500.00 |
Important limitations
Actual project pricing varies by location, materials, labor, access, permits, contractor minimums and scope changes. Use local written quotes before committing.
Interpreting the low/high midpoint
Use office floor area for the unit costs. Keep electrical circuits, data wiring and custom built-ins in the fixed allowance only if the square-foot quotation excludes them.
Low total = quantity × low rate + fixed costs; high total = quantity × high rate + fixed costs. The displayed midpoint is the average of those totals. It is a scenario midpoint, not a statistical estimate or a prediction that the final bill will land there. Raising fixed costs changes both ends equally; raising a unit rate changes only its corresponding end.
