Quick, free insurance calculators from Coverage Estimate. Use them to sanity-check a master policy limit or an HO-6 policy before renewal, then decide whether the numbers deserve a professional look.
These tools run in your browser and explain how each figure is calculated, so you can see what drives the result rather than just a single number.
Compare your master policy building limit with a preliminary reconstruction estimate. It estimates base reconstruction cost, additional rebuilding expenses, a potential coverage shortfall or surplus, your insurance-to-value ratio, and cost per building and per square foot. It also flags when your last professional appraisal may be out of date.
Open calculator → Free Calculator · For Unit OwnersEstimate how much HO-6 coverage a unit owner needs and roughly what it may cost. It suggests limits for dwelling or walls-in coverage, personal property, loss of use, loss assessment and personal liability, estimates your share of the master policy deductible, and compares a preliminary premium range with your state average.
Open calculator →Estimate rebuild costs, depreciation, coinsurance, and deductibles. Each tool shows its inputs, explains the math, and notes its limits.
Estimate what it would cost to rebuild a single-family home, with a low-to-high range, and compare it with your dwelling (Coverage A) limit, insurance-to-value ratio, and extended replacement cost.
Open calculator → Free Calculator · For ClaimsEnter up to 25 items to estimate replacement cost, depreciation, and actual cash value, plus your first payment after the deductible and the recoverable depreciation you may collect later.
Open calculator → Free Calculator · For Property PoliciesCheck whether a property limit meets an 80%, 90%, or 100% coinsurance clause and estimate the insurer payment, coinsurance penalty, and your total out-of-pocket cost.

Open calculator → Free Calculator · For HomeownersConvert hurricane and wind percentage deductibles into dollars and compare deductible options by break-even time and expected cost over the years you plan to own.
Open calculator →A calculator is only as good as what you put into it. A few habits make the output far more meaningful.
For associations, the most valuable output is usually the insurance-to-value ratio. If the replacement cost calculator shows your limit sitting well below the preliminary estimate, that is a signal to look at your policy's coinsurance requirement and to talk with your agent before renewal. Unit owners should pay closest attention to loss assessment and walls-in coverage, because those limits depend on what the master policy leaves out.
Unfamiliar with a term in the inputs? The insurance valuation glossary defines replacement cost, insurance-to-value, loss assessment and dozens of others in plain language.
If a calculator shows a gap, a signed appraisal will tell you how big it really is.
Request an AppraisalCalculators and appraisals answer different questions. A calculator asks, "Does our limit look roughly right?" An appraisal answers, "What would it actually cost to rebuild this specific property, and can we document it?"
