About this tool
What the Home Replacement Cost Calculator does
Home insurance dwelling coverage should reflect the cost to rebuild the house, not its market value, which includes land. Rebuild cost is the floor area times a local rebuilding rate, plus garages, demolition and debris removal, and allowances for upgrades required by current building codes.
Formula
- Base = living area × rate + garage area × garage rate + special features
- Rebuild cost = base × (1 + demolition + code upgrades)
- Shortfall = rebuild cost − dwelling coverage
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Living area | 2,400 sq ft |
| Rebuild cost per sq ft | $220 |
| Garage area | 400 sq ft |
| Garage rebuild cost per sq ft | $80.00 |
| Special features (decks, built-ins) | $25,000 |
| Demolition and debris removal | 5% |
| Building code upgrades | 10% |
| Current dwelling coverage | $500,000 |
| Result | Value |
|---|---|
| Estimated rebuild cost | $672,750 |
| Shortfall in coverage (negative = surplus) | $172,750 |
| Coverage as share of rebuild cost | 74.3% |
| Construction cost before allowances | $585,000 |
How to read the result
After a regional disaster, demand surges can push rebuild costs well above normal. Extended replacement cost endorsements add a buffer.
Review coverage after renovations; many homes are underinsured because improvements were never reported.
