How it works
Keep a building reinstatement budget separate from land value, sale price and household contents.
This is the Canada planning view, with monetary inputs and outputs in CAD. A currency label does not establish that a tax rate, construction price, coverage rule or legal limit has been verified locally. The inputs and limitations below describe the actual scope.

Formula
building sum = (floor area × scoped rebuild rate + clearance + fees) × (1 + contingency).
Calculations retain numeric precision internally. Displayed values are rounded for readability. Quantities that must be purchased as whole units are rounded up only where the formula explicitly requires it.
Read the inputs before calculating
- Insured floor area: Enter the quantity described by the label. The measurement selector converts this physical quantity; it does not change the underlying scenario.
- Verified local rebuild price per area unit: Enter the quantity described by the label. This is a price per displayed unit, so the price converts inversely to the physical quantity.
- Demolition and clearance allowance: Enter the quantity described by the label.
- Professional/statutory fee allowance: Enter the quantity described by the label.
- Rebuild contingency: Enter the quantity described by the label.
- Separate contents replacement value: Enter the quantity described by the label.
- Actual quoted annual premium: Enter the quantity described by the label.
- Annual policy/administration fees: Enter the quantity described by the label.
- Additional installment fee per month: Enter the quantity described by the label.
- Quote sensitivity range: Enter the quantity described by the label.
Reproducible worked example
The following is a fictional arithmetic example, not a local quote, a verified claimant or a market forecast. Its values are included so the formula can be checked. The form does not automatically confirm any verification checkbox.
| Input | Example value |
|---|---|
| Insured floor area (m²) | 150 |
| Verified local rebuild price per area unit (/m²) | 0 |
| Demolition and clearance allowance | 0 |
| Professional/statutory fee allowance | 0 |
| Rebuild contingency | 10 |
| Separate contents replacement value | 0 |
| Actual quoted annual premium | 0 |
| Annual policy/administration fees | 0 |
| Additional installment fee per month | 0 |
| Quote sensitivity range | 15 |
| Output | Calculated result |
|---|---|
| Area-based structure allowance | CAD 0 |
| Modeled building reinstatement sum | CAD 0 |
| Separate contents amount | CAD 0 |
| Entered annual premium | CAD 0 |
| Annual premium and payment fees | CAD 0 |
| Monthly equivalent cost | CAD 0 |
| Low quote scenario | CAD 0 |
| High quote scenario | CAD 0 |
Interpreting a changed assumption
Start with one complete scenario and change only one input when diagnosing a difference. Recheck units, the period of every rate, whether an amount is recurring or one-off, and whether a cost is already included elsewhere. A larger calculated benefit is not evidence that an assumption is more likely to occur.
Limitations
- Use actual policy wording, quotes and jurisdiction-specific requirements. This is a planning worksheet, not a coverage recommendation, insurer quote or determination of a payable claim.
- No insurer premium has been entered. The policy is unpriced, not free.
- Low/high figures vary the entered quote; they are not researched market premiums or underwriting predictions.
- The local rebuild rate is unpriced; this is not a usable insured sum.
- Land and resale-market value are excluded. Listed-building requirements, alternative accommodation, VAT/tax treatment and inflation cover require the policy and surveyor scope.
Frequently asked questions
What does this Home Rebuild Cost result represent?
Keep a building reinstatement budget separate from land value, sale price and household contents. It applies the displayed formula to your inputs; it does not infer omitted facts.
Are the starting amounts verified Canada prices or legal rules?
No. Numeric defaults are illustrative unless an input or dated reference explicitly identifies a researched component. Currency is CAD; local quotes, eligibility and unsupported rules must be entered and verified separately.
What must I check before relying on the result?
Use actual policy wording, quotes and jurisdiction-specific requirements. This is a planning worksheet, not a coverage recommendation, insurer quote or determination of a payable claim.
Can I compare or share different assumptions?
Change one assumption at a time and use the browser-local project or share controls. A shared URL contains the encoded input values; do not include information you do not wish to disclose.
