Calculator guide
Estimate replacement cost by opening count, installed price, and contingency. Use the explicitly labelled inputs below; rates, dimensions, and costs are assumptions, not live quotes.
Formula or method
Estimate the total from entered unit counts, per-unit replacement costs, and the stated contingency. Verify whether each unit quote includes installation.
How to use this calculator
- Set Windows and doors. The interface starts with 8; replace it with the value for your scenario.
- Set Average installed cost ($). The interface starts with 850; replace it with the value for your scenario.
- Set Contingency (%). The interface starts with 10; replace it with the value for your scenario.
- Compare the result with the worked example, then vary one assumption at a time so you can see what changes.
Worked example
Enter Windows and doors = 8; Average installed cost = 850 $; Contingency = 10 %. With those assumptions, the calculator gives Base installed cost: $6,800.00; Contingency: $680.00; Estimated replacement total: $7,480.00; Openings: 8. These outputs are calculated from the same implementation as the interactive tool.
Understanding the result
In this example, Base installed cost is $6,800.00. Contingency is $680.00. Verify measurements, manufacturer coverage, packaging, local code, and site conditions. Quantity and budget estimates do not certify structural or electrical safety.
Limitations and assumptions
- Verify measurements, manufacturer coverage, packaging, local code, and site conditions. Quantity and budget estimates do not certify structural or electrical safety.
- The worked example demonstrates the stated assumptions, not a recommendation about your personal circumstances.
