What this calculator does
Estimate an annual home-insurance budget from a replacement-cost amount and a planning rate you enter.
How to use the calculator
Use the inputs and units named in this form. Select Calculate after changing the values.
How the calculation works
Budget before discount = dwelling replacement cost x planning percentage / 100 + annual endorsements. Discount = that budget x discount percentage / 100. The annual result is the budget minus discount; monthly budget is annual result divided by 12.
Worked example
For a replacement-cost input of 400,000, planning rate 0.55%, annual endorsements 250 and discount 10%, the budget before discount is 2,450. The discount is 245, giving 2,205 annually or 183.75 monthly.
How to interpret the result
Compare the result with the assumptions and units shown above. The calculation uses the values entered into this page.
Assumptions and limitations
The planning percentage is entered by the user; it is not a current market quote. The form does not rate the property using location, construction, catastrophe risk, claims history or insurer rules. Replacement cost is the rebuilding basis, not automatically the home's purchase price.
Common mistakes
Check the units and time period before calculating. An error message means the result cannot be calculated from the current inputs.
Privacy
The calculation runs in your browser. This form needs the numerical inputs shown, not names, account numbers or passwords.
Frequently asked questions
Does the calculator fetch current premiums?
No. Enter a rate or quote-derived assumption for your own comparison.
Are monthly and annual results separate premiums?
No. The monthly result is one twelfth of the annual budget.
What does the discount apply to?
In this model it applies to the combined dwelling-rate budget and annual endorsements.
