Should you renovate or move?

How the Renovate vs Move calculator works

The calculator compares two futures for the same household: stay and renovate your current home, or sell it and buy a different one. It simulates both paths month by month over the number of years you expect to stay, then reports which path leaves you in the stronger financial position, by how much, and which assumptions the answer depends on. It is free, runs entirely in your browser, and does not ask for your name or contact details.

What the comparison actually measures

Most renovate-or-move articles compare a renovation quote with a commission estimate and stop there. That leaves out the things that usually decide the outcome. This model tracks seven of them for each path. Principal you pay on a mortgage leaves your bank account but reduces your debt dollar for dollar, so it is treated as a transfer into equity, not as a cost. Interest is a pure cost, and the difference in interest between a low existing rate and a new loan at today’s rate is often the single largest number in the comparison. Equity is home value minus all debt against it, including any renovation loan. Transaction costs are the commission, seller closing costs, pre-listing repairs, buyer closing costs, moving and setup spending that build no equity at all. Cash flow is the full monthly outlay in each path: mortgage, renovation financing, property tax, insurance, maintenance and HOA dues. Opportunity cost credits the path that consumes less household cash with what that cash could have earned elsewhere. And remaining debt at the end of your horizon matters because a new thirty-year loan has barely been paid down after ten years, while an older loan is well into its principal-heavy years.

Why your existing mortgage rate matters so much

When you move, you do not only buy a new house; you also replace your mortgage. If your current loan is at 3% and the new one is at 6.7%, every dollar of the new balance costs more than twice as much in interest each year, and the new loan amortizes more slowly, so you also owe more at the end. The calculator isolates this effect by re-running the move path with the new mortgage priced at your existing rate and reporting the difference in monthly payment, cumulative interest, remaining balance and total effect. In the worked example below, that single factor accounts for roughly the entire gap between the two paths. Our mortgage rate lock-in guide explains the mechanics and when moving wins anyway.

Transaction costs: the money that builds no equity

Selling and buying is expensive in ways that are easy to underestimate. The defaults start from a total agent commission of 5.7% (Clever Real Estate survey, February 2026), seller closing costs of 1.5% excluding commission (Zillow, September 2025), $5,000 of pre-listing repairs and staging, buyer closing costs of 3% of the new price, and $3,000 for the move itself. On a $550,000 sale and a $900,000 purchase, those defaults total roughly $75,000. Every figure is editable, and the cost of moving vs renovating page itemizes each one with its source.

Equity in both paths

Equity is tracked month by month as home value (appreciating at the rate you set, separately for each home) minus the mortgage balance minus any renovation debt. In the renovate path, the home’s value rises by the estimated value the project adds, credited in the month the work is scheduled to finish. In the move path, the sale pays off the old mortgage, selling costs come out of the proceeds, and the remainder funds the down payment and purchase costs of the new home. By default, equity is measured on a hold basis at the end of the horizon; you can switch on an option that deducts selling costs from both homes at the horizon if you expect to sell either way.

How renovation financing is modeled

You can fund the renovation with cash, a HELOC, a home-equity loan, or a mix. Financed amounts become a second amortizing loan at the rate and term you choose (default 8.31% from the national HELOC average published by Fortune on August 20, 2026). Its interest is a cost and its balance reduces your equity until it is repaid. Soft costs such as design, permits and temporary housing are paid in cash at the start and, because they do not add to the structure, are not included in the base that value recapture is applied to.

Value creation: why a renovation rarely pays for itself

Renovations add value, but usually less than they cost. The 2025 Cost vs. Value report published by JLC and Remodeling puts the resale recoup of a midrange primary-suite addition at about 32%, a midrange major kitchen remodel at about 51%, a midrange bathroom remodel at about 80%, and a minor kitchen refresh above 100%. The calculator’s blended default is 60% of total hard cost including contingency; set it lower for additions and higher for cosmetic work. The difference between what you spend and what the home gains is a real cost of renovating, and the sensitivity analysis shows how much the result moves if your estimate is 20 points too optimistic or pessimistic.

Opportunity cost: what the cheaper path’s cash could earn

Each path keeps a running account of every dollar that leaves the household, compounded at the return you assume on retained capital (default 6%, editable). The path that spends less is credited with the difference. This is what makes a large cash renovation comparable with a move that frees cash, and it is also why results depend on the return you assume; the sensitivity table tests two points either side.

Break-even analysis

Beyond the verdict, the calculator solves for the points where the answer flips: the maximum renovation budget at which renovating still wins, the replacement-home price at which moving becomes competitive, the new mortgage rate that would change the result, and the year in which one path overtakes the other. These are usually more useful than the headline number, because they tell you what you would need to believe for the other choice to be right. See the renovation break-even guide for how to use them.

What the calculator does not do

It does not model income tax, the mortgage-interest deduction, capital-gains tax or the Section 121 exclusion, private mortgage insurance, refinancing, rent-back arrangements, or changes in HOA dues beyond appreciation. It does not know your local market, your contractor, or your family. Every output is an estimate that depends on the assumptions you enter, and a gap smaller than the larger of $10,000 or 2% of your home value is reported as too close to call. The methodology page lists every formula, solver, default and limitation.

Worked example

A household with a $550,000 home, a $300,000 mortgage at 2.75%, a $150,000 renovation estimate and a $900,000 replacement home financed at 6.75% over a ten-year horizon. The numbers below are produced by the engine from those inputs; nothing is hand-entered.

Common questions

Is it cheaper to renovate or move?

Usually renovating, when the project is modest relative to the price jump to the new home and you hold a mortgage rate well below today’s. Usually moving, when the renovation is very large relative to the home’s value, recoups little, or when the replacement home is cheaper. The calculator tells you which applies to your numbers.

How long do I need to stay for renovating to pay off?

It depends on the starting gap. Renovations front-load cost and recoup value slowly, so a short horizon favors whichever path needs less cash up front. The time break-even output shows the year, if any, in which the lead changes.

Does the calculator account for my low mortgage rate?

Yes. It simulates your existing loan at its actual rate and remaining term in the renovate path, and a new loan at the rate you enter in the move path, then reports the isolated dollar effect of the rate gap.

What if my reasons for moving are about location?

Then the financial answer may not be the right answer. The calculator asks why you want a change and flags reasons that no renovation can address, such as schools, commute, lot size or neighborhood, alongside the financial verdict.
