Whole-home budget, as the systems the finishes sit on
A whole-house remodel is electrical service, plumbing, HVAC and insulation before anyone picks a tile. HomeGuide’s whole-house band is $15–$60 per square foot. Kitchen and bath are added as lumps so a $200/sf kitchen is not also inside the $15–$60.
$15–$60per sq ft, whole-house renovationHomeGuide, “How Much Does It Cost to Remodel a House?”, retrieved 23 August 2026. Kitchen or bathroom remodeling on that page is a different $100–$250 per square foot — which is why those rooms are separate lines here.
On 2,000 sq ft at $15–$60, plus a $20,000 kitchen lump and a $12,000 bath lump, 15% contingency, the systems line is $30,000 to $120,000 and the all-in range is $71,300 to $174,800. That width is the survey, not uncertainty about your wiring. Type the kitchen and bath from the other two tools.

What this assumed—
A budget range, never a quote. ADU cost is not this tool. HyreRemodel does not remodel houses.
A whole-home budget is not the sum of the room budgets
A whole-home budget is bigger in one direction and smaller in another, and getting both adjustments right is the difference between a plan and a wish.
Bigger, because of everything that is not a room. Room calculators price kitchens and bathrooms. A whole-home project also has to carry the electrical panel, the heating system, the windows, the insulation, the roof, the drainage — none of which belongs to any single room and all of which are far easier and cheaper to do while the house is already open. These are the lines people leave out, and they are the lines that hurt.
Bigger, because contingency has to be real. On a single room, ten percent is a reasonable allowance. On a whole house, particularly an older one, ten percent is optimistic — you are multiplying the number of walls that get opened and therefore the number of discoveries. Fifteen to twenty percent, held by you outside the contract, is the honest figure for a comprehensive renovation of an older building.
Smaller, because of overlap. Doing several rooms at once genuinely is cheaper than doing them one at a time. One mobilisation, one permit, one set of inspections, one dumpster hire, one skim of the whole house rather than six patch repairs. Trades that would each charge a minimum call-out for a small job price a large one properly. This saving is real and it is one of the better arguments for doing more at once rather than less.
And smaller in a way people forget: you only live through it once. The disruption cost of six separate projects over ten years is far greater than one longer one. That is not a line in a budget and it is a genuine part of the calculation.
The order to spend in, and why it is unglamorous
Almost everyone wants to start with the kitchen. Almost everyone should start further down.
Illustrative allocation. Read it left to right as a sequence, not as a budget — the point is what comes before what.
1. Anything letting water in. Roof, flashings, gutters, grading, basement water. Everything else you do is downstream of this literally and financially. A beautiful kitchen under a leaking roof is a kitchen with a deadline.
2. Structure. Foundation movement, failed beams, sagging floors, anything an engineer has flagged. Expensive, invisible, and the one category where deferring genuinely compounds.
3. Systems: electrical, plumbing, heating. A panel at capacity, galvanised or polybutylene supply, a furnace at the end of its life. These are cheapest by a wide margin while walls are open. Doing a beautiful kitchen and then needing to rewire through it is the canonical sequencing mistake, and it is common.
4. Envelope: windows, insulation, air sealing. Comfort, running cost and durability, all at once. Also the point at which any energy-efficiency incentive available to you is worth checking, since those change and are worth real money.
5. Kitchens and bathrooms. Now. After the services behind them are sound and will not need to come out again.
6. Finishes, then cosmetics. Floors, paint, trim, lighting. The visible layer, deliberately last, because everything above it involves opening things that finishes would have to be cut through.
The exception worth naming. If you are staying five years or fewer and the systems are merely old rather than failing, the calculus changes — you may reasonably decide the next owner deals with the furnace. Just make it a decision rather than an oversight, and disclose honestly at sale.

Line
Why it gets forgotten
When it is cheapest
Electrical service or panel upgrade
Invisible, and nobody wants it. Discovered when a kitchen or an EV charger needs circuits that do not exist.
While walls are open and before finishes go on. Retrofitting through a finished house is several times the cost.
Rewiring older circuits
The house works, so it feels optional — until an inspector or an insurer looks at it.
During a whole-home project, by a very wide margin.
Repiping
Old supply pipe is out of sight and functioning right up until it is not.
While walls and floors are open. This is the single largest overlap saving available.
Heating and cooling capacity
The existing system was sized for the house as it was. A conversion or an addition changes the load.
Planned with the renovation, not bolted on after somebody notices a cold room.
Insulation and air sealing
Not visible and not exciting.
Whenever a wall or roof is open. It will never be this cheap again.
Smoke and CO alarms throughout
People assume it applies only to rooms being worked on.
Frequently required across the dwelling once a permit above a threshold is pulled. Cheap; just budget it.
Lead-safe work practices, pre-1978
Almost universally absent from cost guides. Under 40 CFR Part 745, Subpart E it changes who may do the work and how.
Priced into the bid from the start rather than raised as a change order.
Asbestos assessment in older houses
Nobody thinks of it until a floor or a pipe lagging is disturbed.
Assessed before demolition. Discovering it mid-project stops the job.
Temporary living costs
It is not construction, so it is not in the construction budget.
Planned. On a whole-home project, moving out is often cheaper overall than working around occupants.
Storage for your possessions
Genuinely forgotten every time.
Booked early; it is a monthly cost for the duration and it should be in the number.
Landscaping repair
Skips, deliveries and scaffolding destroy planting and driveways.
Allowed for at the start rather than mourned at the end.
Design fees and, where required, engineering
Treated as pre-project rather than project.
Unavoidable on structural work, and cheaper than the redesign that follows guessing.
Contingency: how much, and who holds it
The two questions are equally important and the second is almost never asked.
Two variables drive it: how many walls get opened, and how old the building is. Both increase the number of discoveries.
How much. The figures above are HyreRemodel planning figures and they are deliberately higher than the ten percent that circulates. Ten percent is a reasonable allowance for one room in a reasonably modern house. It is not a reasonable allowance for opening up a ninety-year-old building, where the discoveries are not exceptional events but the normal course of the work.
Who holds it — the question that matters more. Contingency held by you, in your own account, outside the contract sum, is contingency. Contingency handed to the contractor as part of the price is not contingency; it is budget, and it will be spent, because a number inside a contract sum has been committed.
The practical arrangement. Agree the contract sum for the defined scope. Keep your contingency separate. Release it against specific, written change orders as genuine discoveries arise. This is normal, professional and entirely uncontroversial with good contractors — they would rather have a client with money set aside than one who has to stop the job.
What contingency is not for. It is not for upgrading the tile. Scope changes you choose are not contingency, they are additional budget, and conflating the two is how a contingency evaporates by week four leaving nothing for the actual surprise in week nine. Keep them as separate lines and be strict about it.
And if it is not spent? That is the good outcome. It was never earmarked for anything, and an unspent contingency at the end of a renovation is a project that went well.
The number that caps the whole exercise
Before allocating anything, find out what your street will bear. It is the constraint that makes every other decision easier.
Not a data chart — a reminder. The ceiling is set by the neighbourhood and no amount of money spent inside your walls raises it.
Find it in one phone call. Ask a local agent what the highest sale on your street has been in the last two years, and what they think a fully renovated version of your house would list at. They will tell you, it costs nothing, and it is the single most useful input to a whole-home budget.
What to do with the answer. The gap between what your house is worth now and that ceiling is roughly the amount of spending that has meaningful value support behind it. Beyond it, you are buying use rather than value — which is a perfectly good thing to buy, as long as it is a decision.
The evidence that this is normal. Zonda’s Cost vs. Value data is consistent on the point: outside a handful of cheap exterior replacements, remodeling does not return its cost at resale. The only interior project in the published top five is the cosmetic kitchen at 112.9%. Nobody should approach a whole-home renovation expecting to get the money back, and a plan built on that expectation is built on sand.
If you are considering moving instead, note that the comparison is not price against price — it is your renovation cost against the transaction friction of moving, which is money that buys no asset at all. Since the 17 August 2024 practice changes the largest component of that friction is negotiated rather than posted, so get real local figures rather than a calculator default.
Phasing, if you cannot do it all at once
Most people cannot. Phasing well is a skill and phasing badly destroys the overlap saving that made the whole-home approach attractive.
Phase by system, not by room
Do all the electrical, then all the plumbing, then all the finishes — rather than finishing the kitchen completely and then opening the wall behind it for the bathroom. Room-by-room phasing is intuitive and it is the expensive way.
Never finish over something you will open again
The governing rule of phasing. If a wall has to come open in phase three, do not tile it in phase one. Write the phases down and check them against each other for exactly this.
Do the water and structure work in phase one regardless
It protects everything downstream and it compounds if deferred. This is not the phase to trim.
Get one design for the whole house before phase one starts
Even if it takes years to build. A design done in pieces produces a house that reads as pieces, and it forecloses options in later phases that nobody realised they were foreclosing.
Ask whether one permit can cover multiple phases
Sometimes yes, sometimes no, and it varies by jurisdiction. Worth asking, because separate permits mean separate fees and separate inspection queues.
Keep the same contractor if they are good
The overlap saving partly survives phasing if the same team returns — they know the house, its surprises, and what is behind which wall. Rebuilding that knowledge with each phase is a real cost.
Buy finish materials for all phases at once where practical
Same batch, same dye lot. Tile and flooring bought two years apart will not match, and matching across a house is exactly what makes a phased renovation read as a single project. The flooring calculator sets the waste allowance from the layout and room shape rather than a flat ten percent, which is what decides how much attic stock you end up with.
Re-price each phase before starting it
A number from three years ago is not a budget. Costs move, and the LIRA data below shows they have been moving faster than volume.
The market you are budgeting in
Context for every figure, including the ones you gathered last year.
The headline. The Joint Center for Housing Studies of Harvard University projects roughly $523 billion in annual owner improvement and repair spending by early 2027, with year-over-year growth of just 0.5% by the first quarter of 2027 — a pace that remains positive in nominal terms but is less than overall inflation.
What LIRA measures. The LIRA projects annualised spending on improvements and repairs to owner-occupied homes for the current quarter and the following four, and is designed to identify turning points in the remodeling business cycle.
The supporting signal. Remodeling permits and retail spending on building products have both been flat recently.
HyreRemodel analysis. Nominal growth below inflation means the aggregate is being carried by price rather than by volume: fewer projects, each costing more. For a homeowner planning a large renovation this is a mixed picture. Good contractors have more availability than they did at the peak and there is genuine room to negotiate on schedule and scope. But the cost of the work itself has not come down, so any budget assembled from figures more than a year or two old will be wrong in the direction that hurts.
The instruction that follows. Re-price before you commit, and check the retrieval date on every figure you are relying on — on this site and on any other.
What this budget tool cannot do
The whole-home budget tool publishes no prices. Every figure in the total is one you entered. HyreRemodel holds no dataset of completed projects and will not invent a national average to look authoritative.
It cannot see your house. The age of the building, the state of the systems, what is behind the walls and whether the structure has moved are the four things that determine a whole-home number, and all four need somebody in the building.
The contingency figures are planning judgement. Clearly labelled as HyreRemodel figures rather than data. If your contractor or surveyor knows your building and wants a different number, use theirs.
It does not model financing. How you fund a large renovation — cash, a renovation loan, a line of credit, refinancing and what that does to an existing rate — materially changes what is affordable, and it is a question for a lender.
It does not know your local permit fees, your zoning, or your historic district. Any of the three can change both the budget and what is possible.
Us. HyreRemodel does not perform remodeling work, appraise homes, or rank contractors, and takes no payment to list anyone. Every third-party figure cited is named and dated.
Questions this calculator answers
How much does a whole-house remodel cost?
HomeGuide’s whole-house renovation band is $15 to $60 per square foot. Wet rooms cost more per foot and should be added as their own figures so they are not counted twice.
Why are kitchen and bath separate?
Because $15–$60/sf is the envelope and systems. A kitchen at $150–$250/sf is a different product. Adding both as one $/sf invents a number nobody bid.
