Florida Home Replacement Cost Calculator

Enter your home's square footage, year built, construction type and roof type and this calculator returns an estimate of what it would cost to rebuild it in Florida today, the basis for your policy's dwelling limit. It starts from a $200-per-square-foot base and adjusts for construction, age and roof; an insurer's estimator or an appraisal sets the final number.

Free Florida home replacement cost calculator: square footage, construction, roof and year built give the rebuild cost for your dwelling limit. Not market value.

How to use the home replacement cost calculator

Four inputs to a rebuild-cost planning figure for the dwelling limit on a Florida homeowners policy.

  1. Enter the square footage. The home's living area in square feet, the number on the appraisal or the county property record.
  2. Enter the year built. Homes more than 20 years old, and again more than 40, cost more to reproduce to today's code, so the calculator adds an age factor.
  3. Choose construction and roof type. Wood frame, masonry or block, concrete or CBS, or luxury and high-end construction; then asphalt shingle, clay or concrete tile, metal or flat roof.
  4. Compare the estimate with your dwelling limit. Read the rebuild figure and check it against Coverage A on your declarations page. If the policy is well below it, ask your carrier to rerun its replacement cost estimator or get an appraisal.

Frequently Asked Questions

What is replacement cost on a homeowners policy?

It is what it would cost to rebuild the house as it stands today, at current labor and material prices and to current building codes: not what you paid, not the tax assessor's value and not the market price, which includes the land. The dwelling limit (Coverage A) on a Florida homeowners policy should track this rebuild figure, which is what the calculator estimates.

How does the replacement cost calculator work?

It multiplies your square footage by a $200-per-square-foot Florida base, adjusts for construction (wood frame 1.0, masonry 1.15, concrete 1.25, luxury 1.5), adds a factor for homes over 20 and over 40 years old because older homes cost more to reproduce to code, and adds or subtracts a per-square-foot roof adjustment for tile, metal or flat roofs. It is a planning figure; carriers run their own replacement cost estimator before they bind.

Why is replacement cost different from market value?

Market value prices the land, the neighborhood and demand; replacement cost prices labor and materials. In much of coastal Florida the lot is worth more than the house on it, so market value overstates rebuild cost, while in an inland county with cheap land an older home can cost more to rebuild than it would sell for. Insuring to market value is the wrong number in both cases.

What happens if my home is underinsured?

If the dwelling limit is below the rebuild cost, a total loss leaves you paying the difference, and standard homeowners forms pay full replacement cost on a partial loss only when the limit is at least a set share of the rebuild cost. The underinsured-home guide linked below walks through the 2026 gap; this calculator is the two-minute check before you call your carrier about the limit.

How often should I update my dwelling limit?

At every renewal, and after any addition, kitchen or bath remodel, roof replacement or jump in construction costs. Rebuild costs in Florida have moved up for several years, so a limit set at purchase can trail the real number within a few years. Running this calculator at renewal and comparing it with the carrier's estimate takes two minutes.

Does a higher replacement cost mean a higher premium?

Yes. The dwelling limit is the base the rate applies to, so insuring an extra $50,000 of rebuild cost raises the premium, and the hurricane deductible, usually a percentage of the dwelling limit, rises with it. The point is to carry the right number, not the highest one; the homeowners insurance calculator shows what a given rebuild value costs to insure in your region.
