Home Renovation Cost Calculator

How this renovation cost calculator works

It builds your budget the way a contractor's estimate does — from the biggest line down to the buffer:

Renovation & remodel cost per square foot (2026)

Cost per square foot is the fastest way to size a project. These are approximate 2026 US national ranges for the work itself — a rough cost per square foot to remodel each space — with kitchens and bathrooms the most expensive because of plumbing, wiring, cabinetry and tile.

A full gut renovation adds roughly $60–150/sq ft on top; high-cost cities can add 30–50%.

Renovation cost by room (2026)

Costs vary most by which room you touch. Rooms with plumbing and wiring — kitchens and bathrooms — cost the most per square foot; bedrooms and living spaces are the cheapest. Here are typical all-in project ranges for 2026, and what each usually includes.

Ranges are 2026 US national ballparks — your figure depends on size, finishes, home condition and location. Use the calculator above and get local quotes.

How much does a 1,000 sq ft basement renovation cost?

A finished basement is one of the best-value ways to add living space, and size makes the math easy. At a mid-range $55–90 per square foot to finish, a 1,000 sq ft basement renovation runs roughly $55,000–90,000 for the work itself — framing, insulation, drywall, flooring, egress, lighting and a basic bathroom. A budget finish (paint, flooring and simple framing) can land near $30,000–55,000, while a high-end basement with a wet bar, full bath and home theater can pass $100,000+.

Add the extras the basement calculator above includes: permits ($500–2,000), inspection, waterproofing or a sump pump if needed ($1,000–5,000), and a 10–20% contingency — older basements often hide moisture, low ceilings or outdated wiring. Set the project to Basement finishing, enter 1,000 sq ft, and edit the cost per square foot to match local quotes.

Cost to remodel a 1,500 or 2,000 sq ft house

Whole-house numbers scale with floor area and how deep you go. Plug your size into the whole-house renovation cost calculator above, or use these 2026 ranges — about $20–50 per square foot for cosmetic work, $50–120 mid-range, and $120–250+ for a full gut — to see the cost per square foot to remodel two common sizes:

Kitchens and bathrooms take the biggest bite, so a home with two full baths and a large kitchen sits at the top of each range. For your own number, set the project to Whole-house remodel, enter your square footage, and pick a finish level.

Renovation costs for house flippers and investors

If you're renovating to sell, the budget is a business decision, not a wish list. A house-flip renovation calculator has to answer one question: will the after-repair value (ARV) comfortably beat your purchase price plus renovation, holding and selling costs? A common guideline is the 70% rule — pay no more than 70% of ARV minus your renovation budget — which keeps room for profit and overruns.

• Spend where buyers pay back — kitchens, bathrooms, fresh paint, flooring and curb appeal return the most; skip personal or over-improved finishes for the neighborhood.
• Budget holding costs — loan interest, taxes, insurance and utilities for every month the project runs; a longer timeline quietly eats the margin.
• Always carry a 10–20% contingency — flips uncover the same surprises as any renovation, and a blown budget turns profit into loss.

Use the calculator to price the renovation, then check the resale value added it reports and your financing cost with our home loan and personal loan calculators before you commit.

Where your renovation money actually goes

On most projects, labor is 20–35% of the bill and materials the rest — but a few big-ticket items dominate. In a kitchen, cabinets alone are usually the single largest line:

• Cabinets & hardware — about 25–35% of a kitchen
• Labor & installation — roughly 20–35%
• Appliances — about 10–15%
• Countertops — roughly 10%
• Flooring — about 7%
• Lighting, electrical, plumbing, backsplash, paint & disposal — the remainder

Typical 2026 component prices to sanity-check a quote: countertops $400–4,300; flooring $1–35 per sq ft installed; tiling $860–2,800; plumbing work $100–1,000; electrical & lighting $200–700; interior paint $200–600 per room; and skilled labor $50–110 an hour. The single biggest way to move the total is the finish level you pick for cabinets, counters and flooring.

The costs most people (and most calculators) forget

The headline “cost per square foot” is only the start. These extras routinely add thousands, and many quick calculators leave them out entirely:

• Permits — roughly $50–500 for small jobs and $500–2,000 for large ones; structural, electrical and plumbing work almost always needs them.
• Inspections — about $70–1,300 where special inspections are required.
• Demolition & disposal — around $4–17 per sq ft to tear out, plus $300–1,800 for skips and dump fees.
• Design — an interior designer is $50–500 an hour, or about $5–15 per sq ft.
• Contingency — the big one. Older homes hide rot, mould, outdated wiring and failing plumbing; 10–20% (sometimes more) keeps a surprise from stopping the job.

18 ways to save money on your renovation

Renovations almost always cost more than the first sketch. These are the highest-impact ways real homeowners and builders trim a budget without wrecking the result.

Planning & quotes

• Get at least three itemized quotes and compare them line by line — not just the bottom number.
• Lock the design before work starts. Mid-project changes (“change orders”) are the number-one budget killer.
• Research local material prices so you can tell whether a contractor's allowances are realistic.
• Build in a 10–20% contingency so one surprise doesn't blow up the whole plan.

Scope & layout

• Keep the layout. Moving sinks, toilets, gas lines and walls is where costs explode — leave plumbing and load-bearing walls where they are.
• Reface, don't replace. Sound cabinet boxes can be refaced for a fraction of new units.
• Keep what still works — good appliances, fixtures and floors — and upgrade only what matters.
• Phase big projects — do the essentials now and the nice-to-haves later.

Materials

• Choose look-alike materials: quartz instead of marble, luxury vinyl plank instead of hardwood, stock or semi-custom cabinets instead of custom.
• Shop Habitat ReStore, salvage yards and open-box/clearance for deep discounts on materials and fixtures.
• Buy floor models, last season's styles and end-of-line tile.
• Price-match big-ticket items and ask suppliers to match online prices.
• Use your contractor's trade discount at supply houses — just give the installer's name.
• Sell your old cabinets, doors, fixtures and appliances on Marketplace to recoup cash.

Labor & timing

• Do the sweat-equity jobs yourself: demolition, daily clean-up, painting, hauling and installing hardware.
• Book in the off-season (late fall and winter), when contractors are slower and often price keener.
• Bundle projects with the same trades to save on call-out and mobilisation fees.
• Get everything in writing — a fixed-price contract, payment schedule and clear scope protect your budget.

How long does a home renovation take?

Timelines matter for budgeting — a longer job means more labor and, if you move out, more temporary-housing cost. Rough 2026 durations once work actually begins:

Add weeks to a few months before tools swing for design, quotes, permits and material lead times — custom cabinets and windows can take 6–12 weeks to arrive.

DIY vs hiring a contractor

Doing some work yourself is the fastest way to cut labor, which is a fifth to a third of the bill — but only where it's safe and legal. The rule of thumb: DIY the cosmetic and muscle work, hire out anything behind the walls.

• Good to DIY — painting, demolition, hauling and clean-up, simple tiling, installing hardware and fixtures, floating floors, flat-pack furniture and landscaping.
• Leave to a pro — electrical, plumbing, gas, HVAC, roofing, structural or load-bearing changes, and anything that needs a permit or inspection. A botched DIY on these often costs more to put right than hiring out in the first place, and can void insurance or fail at resale.

Be honest about your skills, tools and time. If a mistake could flood, shock, or hold up the whole project, pay the pro.

How to budget your renovation, step by step

1. Set a realistic total using the calculator above plus your own priorities.
2. Get three itemized quotes and compare them against your estimate.
3. Split must-haves from nice-to-haves so you know what to cut if bids come in high.
4. Add a 10–20% contingency (more for older homes).
5. Decide how you'll pay before you sign — see the options below.
6. Track every expense against the plan and approve any change order in writing.

How to pay for a renovation (2026)

The cheapest money is your own, but most big projects use borrowing — a dedicated home renovation loan or home improvement loan, or an equity-backed option. As a rule, equity-backed loans (a home equity loan or HELOC) have the lowest rates because your home is collateral, personal loans are higher, and credit cards are highest unless you use a 0% intro offer and clear it in time.

Whatever you choose, see the real monthly cost first with our home loan calculator or personal loan calculator, and only borrow what your budget can comfortably repay.

Are home renovation costs tax deductible? (2026)

For most homeowners, everyday remodeling isn't immediately tax deductible — but a few important exceptions are worth knowing before you file:

• Home equity loan or HELOC interest — generally deductible when the loan is used to “buy, build or substantially improve” your home, on the first $750,000 of mortgage debt. This IRS rule (Publication 936) was made effectively permanent through at least 2028 by 2025's tax legislation, so a renovation financed with home equity can carry a real tax break.
• Your cost basis — capital improvements such as a new kitchen, addition, roof or HVAC add to what you paid for the home, which can lower the capital-gains tax when you sell. Keep every receipt.
• Medically necessary changes — work like ramps, wider doorways or an accessible bathroom can count as a deductible medical expense to the extent it doesn't raise the home's value.
• Rental or home-office space — improvements to a rented unit or a qualifying home office may be depreciated or deducted.

This is general information, not tax advice — rules change and depend on your situation, so confirm with a tax professional. To size the borrowing side, check the monthly cost with our home loan calculator or personal loan calculator.

Renovation ROI: does a remodel pay off at resale?

Partly — but rarely in full. In 2026's Cost vs Value data, small targeted jobs recoup the most: a minor kitchen refresh can return close to 100% (and exterior fixes like a new garage or entry door often exceed 100%), while a mid-range bathroom recoups roughly 70–80%. Big-ticket work returns less — major kitchen overhauls and room additions typically recoup about 35–50%. The calculator shows a typical resale value added (your home value after the renovation) for your project, but it varies by market, so renovate mainly for how you'll live in the home. If you're borrowing for the work, our home loan and personal loan calculators show the monthly cost.

Which renovations add the most value? (2026)

If resale is on your mind, small exterior and cosmetic jobs usually beat big remodels on return. Recent national Cost vs Value-style reports put the best-recouping projects roughly like this — figures vary by year, region and how your home compares with the neighborhood:

The pattern is consistent: fresh paint, curb appeal and modest kitchen and bath updates return the most, while additions and luxury finishes return the least. A handy guardrail is the 30% rule — try not to sink more than about 30% of your home's value into one renovation, and avoid over-improving beyond what nearby homes support.

The order of work: why sequencing protects your budget

A renovation is not a pile of independent jobs; it is a chain, where each stage depends on the one before it. Get the order right and the work flows; get it wrong and you pay to undo finished work so a missed step can be done underneath it. The broad sequence rarely changes: design and permits first, then demolition, then any structural or framing changes, then the rough-in of electrical, plumbing and heating while the walls are open, followed by inspection, insulation and closing up, and only then the finishes — flooring, cabinets, tiling, paint and fixtures — before the final fit-out and clean. Skipping ahead to the satisfying parts is the classic way a budget quietly overruns.

One simple principle sits underneath the whole plan: the dirty, dusty and wet trades go first, and anything you would hate to scratch, splash or coat in dust goes last. That is why wiring and pipework happen while the walls are open, and why flooring, cabinets and the final coat of paint wait until the mess is over. Break the rule and the costs are immediate — new flooring laid before the plumber has finished gets lifted and relaid, cabinets fitted before an electrical inspection get pulled off the wall, and a fresh paint job gets ruined by later demolition next door. Each of these is rework you pay for twice, and none of it shows up in a cost-per-square-foot estimate.

Sequencing also governs your timeline and your cash flow, because trades have to be booked in order and a slip in one stage pushes every stage after it. Long-lead items are where careful planning pays off most: windows, custom cabinets and some tiles can take weeks or months to arrive, so they need to be ordered early even though they are installed late — a missing delivery can freeze an entire project that is otherwise ready to move. Build your plan as ordered stages with the inspection gates in the right places, line up each trade to follow the last, and order the slow items up front. The estimate above tells you what a renovation should cost; respecting the order of work is a large part of what keeps you near it.

• Rough-in before close-up — wiring and pipes go in while the walls are open.
• Finishes last — floors, cabinets and paint wait until the mess is done.
• Order long-lead items early — even though they are installed near the end.
