Home Replacement Cost Calculator

Built and maintained byKapil LodhiReviewed and updated June 2026 — Based on published homeowners insurance industry guidance and regional construction cost data across all 50 US states

How much does it cost to replace a home in 2026?

The cost to replace a home in 2026 typically runs $90 to $260+ per square foot, depending on construction quality, location and home age. A standard 2,000 sq ft home costs roughly $180,000 to $330,000 to fully rebuild at current materials and labor prices. This is your home's replacement cost value (RCV) — the figure homeowners insurance uses to set your dwelling coverage limit, not your home's market value. Use our free calculator above to get an instant, personalized replacement cost estimate.

Home replacement cost calculator — by size

Our home replacement cost calculator updates your estimate in real time as you select size, construction quality, age, special features and US state. The table below shows typical replacement cost ranges at a standard quality level.

How to calculate the replacement cost of your home

The simplest way to calculate your home's replacement cost is with this formula: home square footage × local rebuild cost per square foot = replacement cost value. For example, a 2,000 sq ft home in an area where rebuild costs average $135 per square foot would have an estimated replacement cost of $270,000. This basic formula gives a reasonable starting estimate, but it doesn't account for construction quality, special features, or local permit and demolition costs — which is why our calculator above layers in those adjustments automatically.

Beyond the basic formula, there are a few other ways to determine your home's replacement cost, each with a different level of accuracy:

• Online calculator (this tool) — Fast, free, and useful for a ballpark figure before talking to your insurer.
• Insurance company estimate — Most insurers use specialized software (such as Marshall & Swift/Verisk 360Value) that factors in your home's exact specifications.
• Licensed appraiser or contractor — The most accurate method, since it involves an in-person inspection of materials, finishes, and local building codes.

Remember: replacement cost should never include the value of your land, since land doesn't need to be "rebuilt" after a covered loss.

Replacement cost vs. market value vs. actual cash value

These three numbers are easy to confuse, but they answer very different questions. Replacement cost is what your insurer uses to set your dwelling coverage — it has nothing to do with what your home would sell for.

The 80% rule — am I underinsured?

Most homeowners insurance policies require you to carry dwelling coverage equal to at least 80% of your home's replacement cost to receive full payment on a claim. This is known as the 80% rule or coinsurance clause. If your coverage falls below that threshold, your insurer will only pay a proportional share of any claim — even for partial damage, not just a total loss.

The formula insurers use is: payout ratio = coverage carried ÷ (80% × replacement cost). For example, if your replacement cost is $400,000, you'd need at least $320,000 in dwelling coverage. If you only carry $280,000, your payout ratio drops to 87.5% — meaning a $50,000 claim would only pay out $43,750, leaving you responsible for the remaining $6,250 before your deductible. Enter your current dwelling coverage limit in the calculator above to see your own coinsurance position.

Why rebuilding costs more than building new

A common assumption is that rebuilding a destroyed house should cost about what the same house costs to build on an empty lot. It routinely costs more, and the reasons are worth knowing before a policy limit is set:

• Demolition and debris removal. Before anything is built, what remains has to be cleared, sorted and hauled away — a cost that simply does not exist on a vacant lot.
• Building to current code. A house built decades ago was built to the code of its time. Rebuilding happens under today's requirements, which can mean upgraded electrical, insulation, structural connections, egress and more.
• One house at a time. Production builders spread costs across many homes. A single rebuild carries its own mobilization, supervision and procurement, with none of that efficiency.
• Demand surge. After a widespread event, local contractors and materials are in short supply across a whole region at once, and prices move accordingly.
• Site constraints. An established lot with mature landscaping, tight access and neighboring houses is harder to work than open ground.

For context on the base construction figure, national residential construction costs have been running near $162 per square foot before land and contractor overhead, and our home building cost estimator covers how that varies by size and specification.

The endorsement that decides whether you can actually rebuild

Dwelling coverage is a number, and a total loss is an event. If the number was set too low, or costs rose after it was set, the gap is yours. Two optional endorsements exist precisely for this:

That third one is easy to overlook and frequently decisive on an older home, because a standard policy may pay to replace what was there rather than what code now requires. Ask your agent specifically whether you carry it and at what limit.

The scale of the underlying problem is substantial: industry estimates put roughly three in four US homes below what it would actually cost to rebuild them. That is not usually the result of anyone choosing to be underinsured — it is a limit set years ago that construction costs have since overtaken.

When to revisit the number

Replacement cost is not a figure to set once. Review it when any of these happen:

• You finish a basement, add a room, or convert an attic or garage into living space — new square footage has to be insured square footage.
• You upgrade materially: a kitchen, bathrooms, flooring, or replacing builder-grade finishes with something better.
• Construction costs in your region move sharply, which they have repeatedly in recent years.
• You add structures — a detached garage, workshop or substantial outbuilding, which may fall under a separate limit.
• At renewal, as a matter of routine. An annual inflation adjustment applied by the carrier is a blunt instrument and may not track your local market.

Keep documentation that would help you prove what was there: photographs of each room, receipts for major upgrades, and a record of improvements. After a fire or storm, reconstructing that from memory is difficult — our fire damage restoration cost calculator covers what the claim process involves when the loss is partial rather than total.
