How Much Does It Cost To Renovate A House?
On average, Americans spend $13,000 on a single home renovation project1. Following the effects of COVID-19, homeowners spent 48% less on their renovation costs than prior to the pandemic2, likely due to financial strain. People reported being more cautious with their reno spend by turning to do-it-yourself projects and more budget-friendly finishes to keep overall renovation costs down.
Depending on the type of house and project, the average recommended spending for remodeling projects will vary. The National Association of Home Builders (NAHB) suggests spending a certain percentage of the home’s total value based on the room or upgrade, detailed in the chart below.

Cost To Completely Renovate A House
The average cost to completely renovate a house is $15,000 – $200,0004. Depending on the characteristics of the build, the price can change drastically. The final price tag typically depends on any structural or mechanical repairs, square footage, underlying issues, location and materials used.
Depending on their characteristics, remodels will fall under one of three types of categories: high-end, mid-range and low-end.
- High-end: Major renovations with designer materials and high-end products.
- Mid-range: Renovations for projects typical in second homes with mid-range products and materials.
- Low-end: Remodels with minor upgrades typically found in starter homes, many of which are self-funded or DIY, and use low-end products.
Below you’ll find the national averages of high-, mid- and low-end costs for popular renovations. The calculations include the return on investment to the nearest percentage based on Remodeling’s 2020 Cost vs. Value Report5.
Depending on the square footage, the average cost to gut and remodel a house can be anywhere between $100,000 – $200,000⁴. Gut renovation cost per square foot ranges between $60 – $150 and includes new plumbing, appliances, structural improvements, a new roof and an HVAC.
When it comes to renovating the inside of a home, you have to factor in the cost of demolishing the interior. This typically costs $1,200 – $4,700 with a high end of about $10,000⁴. The total price includes the removal of debris, dumping fees, permits and tear out. Once everything is cleared out, you have to factor in the costs depending on the specific project.
A popular interior renovation that homeowners tend to do is removing interior walls. This costs $300 – $10,000⁴, however, the price can range depending on whether a wall is load-bearing or not. Load-bearing walls serve as the primary support of the home, so removing them involves a great deal of guidance.

Cost To Renovate A Kitchen
Kitchens are traditionally one of the first rooms homeowners remodel and doing so cost $23,000 – $135,000. When buyers look at homes that are for sale, a modern kitchen is what often encourages them to make an offer. With budgets below $4,000, homeowners avoid making upgrades to countertops, cabinets and appliances in the kitchen7.

Home Renovation Cost FAQs
Still unsure whether to renovate or repurchase? Take a look at these commonly asked questions about home renovation costs.
Is It Cheaper To Remodel Or Build A New House?
The cost of remodeling is typically less than building a new home. Residential spend for purchasing new homes with upgraded kitchen and bathrooms typically exceeds that of remodels, their industries ticking $77 billion and $62 billion, respectively7. To fund your project, consider getting tax-free funds for your remodeling project with cash-out refinancing.
Is Remodeling A Home Worth It?
Remodeling can be expensive but investing money in your home can increase the value for a higher ROI when reselling. It can also make living in your home more enjoyable and lucrative. Say you invest in new siding or landscaping for your home. This will boost its curb appeal and resale value, making it easier to sell your home and boosting the odds that you’ll generate the highest possible profit when you do sell.
Replacing your roof, repairing a sagging foundation or investing in new HVAC equipment will fix serious problems in your home. By tackling these problems, you’ll prevent future, even costlier problems such as water damage, mold or cracking walls.
Average Cost Per Square Foot
The more square footage involved in your home renovation project, the more expensive it will be. Renovating an entire home will cost, on average, $10 – $60 per square foot5. As a result, the more square footage involved in your renovation project, the more you’re likely to pay.
