- The calculator gives a ballpark from square footage and material choices; it cannot see your walls, building rules or hidden conditions.
- Installed flooring costs more than material alone: labor, removal, subfloor prep and finish all add to the per-square-foot figure.
- Add roughly 10 to 20 percent contingency, and 15 to 25 percent for design and permit work when filings are required.
- Access, such as walk-ups, elevator windows and board hours, often changes the price as much as finish level.
- Only a written, itemized quote based on a site visit is a price you can contract against.
The calculator above gives you a number in about a minute. This page explains where that number comes from, what it leaves out, and how to turn it into a budget you can defend in front of a bank, a board or a spouse. If you only read one line: use the result as a starting range, never as a price.
We built this page for New York City and Long Island renovations, where the same room can cost very different amounts depending on the building. A kitchen in a fifth-floor walk-up with no elevator is a different job from the same kitchen in a detached house with a driveway. When you want a figure you can sign, request a free written estimate.
1. What the Calculator Does and Does Not Do
The calculator multiplies the square footage you enter by per-square-foot rates for the items you select: flooring, cabinets, countertops, demolition, garbage and debris removal, permits and other line items. It then adds them. That is a useful structure because it forces you to think in categories, and categories are how contractors build quotes.
What it cannot do is look at your home. It does not know that your plaster is cracked, that the bathroom floor slopes toward the tub, that the building prohibits work after 5 PM, or that the cast iron stack behind the vanity needs replacing. Those unknowns are why the estimate is informational. The calculator's own footnote says final pricing varies with project needs, local fees and material choices, and we agree.
Use it for three things:
- Scope sizing. Does this project feel like a $20,000 job or a $120,000 job?
- Trade-offs. What happens to the total if you choose vinyl instead of marble?
- A conversation starter. Print or screenshot the result and bring it to your first estimate visit so we can explain the gaps line by line.
2. The Flooring Inputs, Explained
The calculator offers four flooring options with simple per-square-foot figures: wood at $12, ceramic at $8, marble at $20 and vinyl at $5. These are baseline material-level planning figures. Installed costs in the New York metro are higher because labor, removal and prep are separate work.
| Flooring type | Calculator baseline per sq ft | Typical 2026 installed planning range |
|---|---|---|
| Wood | $12 | Engineered or solid hardwood about $12 to $28 per sq ft installed |
| Ceramic | $8 | Standard ceramic or porcelain tile about $20 to $45 per sq ft installed |
| Marble | $20 | Natural stone runs higher than standard tile; large-format and mosaic work higher still |
| Vinyl | $5 | Luxury vinyl plank about $6 to $15 per sq ft installed |
Three add-ons commonly separate the calculator from a quote. Subfloor prep and leveling adds about $2 to $8 per square foot. Removing the old floor adds roughly $2 to $7 per square foot, and removing tile runs $4 to $12. Refinishing instead of replacing hardwood is a separate route at about $4 to $10 per square foot.
If you are unsure which material belongs in which room, tell the calculator to run both and compare. Wet areas need waterproofing, which adds about $3 to $10 per square foot to a tile floor or shower, and which no flooring slider can show you.
3. Cabinets and Countertops
Cabinets and counters often account for the largest share of a kitchen budget, and they are where the calculator's simplicity matters most. Linear footage, cabinet construction (stock, semi-custom or custom), door style, hardware and counter material all change the price. A stone slab with a waterfall edge and a laminate counter are not the same line item, even when both are listed as "countertops."
For planning, remember our typical 2026 ranges for whole rooms: kitchens roughly $25,000 to $85,000 or more, and bathrooms roughly $30,000 to $60,000 or more. Those include plumbing, electrical, tile, labor and fixtures that a cabinet-only estimate does not. If your calculator result for a full kitchen lands far below $25,000, scope is probably missing: appliances, lighting, plumbing relocation or ventilation.
You can see how we price kitchens on our kitchen remodeling page for NYC.
4. Demolition and Garbage Removal
Demolition looks cheap on paper because it is just removal. In New York it is rarely cheap in practice.
Selective interior demolition and haul-away typically runs about $8 to $30 per square foot, depending on access, number of floors, the amount of debris and any hazardous materials. A ground-floor house with a dumpster in the driveway sits at one end. A walk-up apartment where debris is carried down four flights in contractor bags and carted away sits at the other.
Several things drive the figure:
- Access: stairs versus elevators, loading-dock rules, freight elevator reservation fees.
- Hours: some co-ops and condos limit work to weekdays from roughly 9 AM to 5 PM, and city rules generally limit construction to weekday daytime hours unless a variance is approved.
- Disposal: carting, container placement and protecting the building's common areas.
- Hazmat: older buildings may need asbestos or lead assessment before anything is disturbed. The EPA's asbestos information explains why. Any suspect material has to be surveyed and, if present, abated by a certified firm.
Garbage disposal in the calculator is a stand-in for those costs. If your building has strict rules, tell us early.
5. Permits, Design and Fees
The calculator includes an allowance for permits, but it cannot know whether your scope needs one. In New York City, most construction work needs a Department of Buildings permit, and alterations are filed through DOB NOW by a registered design professional, either a licensed Professional Engineer or a Registered Architect. Cosmetic work such as painting generally does not, though co-op, condo and landlord rules still apply.
Design, engineering, expediting and permit fees often add roughly 15 to 25 percent on top of construction when a filing is needed. Landmarked buildings often add about 15 to 20 percent to time and budget, because the Landmarks Preservation Commission reviews exterior changes and some interior ones. The DOB's page on how to obtain a permit outlines the process. Our permit checker gives you a quick first read, and our guide to navigating NYC permits for renovation covers the steps in more depth.
Outside the city, permits come from your local building department: a town or village on Long Island, or a municipal construction office in New Jersey.
6. How to Interpret Your Result
Think of the calculator output as the middle of a range, not a point. A sensible way to read it:
- Subtract what you will not do. If you plan to keep existing cabinets, remove that line.
- Add what the calculator cannot see. Waterproofing, subfloor repair, electrical upgrades and ventilation are common omissions.
- Add design and permit fees, about 15 to 25 percent when filings are required.
- Add a contingency. Ten to twenty percent is normal; pre-war buildings may need the higher end.
- Compare against typical per-square-foot ranges. A cosmetic refresh is roughly $100 to $250 per square foot; a mid renovation with kitchen and bath roughly $200 to $400; a full gut roughly $250 to $500 or more; high-end or structural work $500 to $1,000.

7. A Worked Example
This is an illustration with round numbers, not a quote or a past project. Suppose you own a 400 square foot one-bedroom and want to replace the floor with engineered hardwood and refresh the paint.
| Line item | Planning range |
|---|---|
| Remove old flooring, 400 sq ft at $2 to $7 | $800 to $2,800 |
| Subfloor leveling in part of the unit, say 150 sq ft at $2 to $8 | $300 to $1,200 |
| Engineered hardwood installed, 400 sq ft at $12 to $28 | $4,800 to $11,200 |
| Interior painting for a one-bedroom | $2,500 to $5,000 |
| Subtotal | $8,400 to $20,200 |
| Contingency at 10 to 20 percent | about $840 to $4,040 |
The calculator might show roughly $4,800 for the wood alone at $12 per square foot, which is the low end of the installed range. The difference between $4,800 and $11,200 is finish, grade, pattern and condition of the subfloor, not an error. That spread is why a site visit matters.
8. Local Price Drivers by Neighborhood
Square footage is only half of the story. Here is how location tends to change the real number.
East Village, Manhattan (10003, 10009). Tenement walk-ups and small apartments with tight stair access mean hand-carried materials, limited staging space and sometimes rent-stabilized building rules. Smaller rooms often cost more per square foot because fixed costs spread over less area.
Crown Heights, Brooklyn (11213, 11216, 11225, 11238). Limestones, brownstones and pre-war apartments, some in Landmarks Preservation Commission districts. Exterior-facing changes may need LPC review, and old plaster and uneven floors raise prep costs.
Elmhurst, Queens (11373). Co-ops, attached homes and multifamily buildings. Co-op alteration agreements and shared walls shape sequencing; multifamily buildings need care around neighboring units.
Tottenville, Staten Island (10307). Coastal Victorian homes in or near flood zones. Materials near grade may need to be flood-resistant, and moisture surveys matter before new floors go in.
Hewlett, Nassau County (11557). Five Towns colonials with some flood-zone pockets. Permits come from the town or village, and basements may need water-tolerant flooring.
Fort Lee, New Jersey (07024). High-rise condos and co-ops with building rules on elevators and hours, plus municipal permits under New Jersey's Uniform Construction Code.

10. Why a Licensed Contractor's Quote Beats a Calculator
A calculator is a spreadsheet. A contractor's quote is a plan. The difference matters most where mistakes are expensive: waterproofing that hides behind tile, subfloors that decide whether a new floor squeaks or cracks, and permit filings that can stall a job for weeks.
N.Y. Renovation Services is a licensed and insured design-and-build team, so the person who prices your project is working alongside the people who will build it. We visit, measure, check access and building rules, and then write an itemized contract that shows materials, labor, demolition, carting and permits as separate lines. There are no hidden fees to find later, and allowances for fixtures and finishes are named, so you can see where a decision could move the price.
We also handle the paperwork that trips up first-time renovators: DOB filings through your design professional, alteration agreements and insurance certificates for co-op and condo boards, hazmat testing in older buildings and the sequence of trades. Our focus is gut renovation, tile, flooring, interior painting and exterior painting, which together make up most of what the calculator estimates. And five percent of your total project cost is donated to a nonprofit of your choice.
Here is what that looks like in practice. If your calculator result is lower than our quote, we sit down with both documents and walk the difference line by line, so you can see whether it is waterproofing, access, a subfloor repair or a finish upgrade. If a line does not serve you, we remove it and show you the new total. If your result is higher than our quote, we explain what we are assuming and what could change once walls are open. Either way, you leave the conversation knowing what you are paying for and why, which is the part no online tool can offer.
Phasing is another option we raise early. Many owners do flooring and painting now and save the kitchen for next year, or tile the bathroom first because the waterproofing is the most urgent piece. A phased plan costs a little more in mobilization but fits a tighter budget, and an itemized quote makes it easy to see where to split.
11. Next Steps: Get a Written Estimate
Take the number from the calculator and write down three things: your address and building type, the rooms in scope, and the finishes you are leaning toward. Add your ideal start date and any board or landlord restrictions you know about. That is all we need to schedule a visit.
At the visit we measure, photograph conditions, check access and ask the questions a calculator cannot. Within a few days you receive a written, itemized quote. It separates required work from optional upgrades, states who files permits and lists what is excluded, so you can compare it fairly against other bids. If you are still choosing, our checklist for hiring a renovation contractor in NYC shows what to verify, including the contractor's license.
Quotes are free, and you are under no obligation. You can start online, call or text us, Monday through Saturday, 8 AM to 5 PM.
Safety Note: All work follows OSHA 30 safety and EPA Lead-Safe practices for pre-1978 homes. Check local permit requirements before starting.
