How This Renovation Calculator Works
First, this renovation calculator multiplies your area by a typical cost per square foot for the room and quality tier you choose. Then it adjusts the result for your region, with 0.85 for a lower-cost area and 1.3 for a higher-cost metro. Because real prices depend on your contractor, your materials and local permit fees, the answer is a range of 15% either side of the midpoint. Therefore, think of it as a starting point for budgeting, not a formal quote.
First, pick the room, the area and the unit.
Next, choose Basic, Standard or Premium and your cost level.
Finally, review the range, the breakdown and the tier comparison.
Formula
Area × cost per sq ft × regional level = midpoint · range = midpoint ± 15%
Renovation Calculator Example
For example, a 150 sq ft kitchen at the Standard tier in an average-cost area has a midpoint of $22,500. As a result, the range is about $19,125 – $25,875. Overall, cabinets, countertops and labor drive most of that figure.
Meanwhile, a 12 sq m bathroom at the Standard tier in an average-cost area comes to about €20,202 – €27,332 when you choose euros. In this case, the calculator converts 12 sq m to square feet first.
Renovation Calculator Costs per Square Foot and Square Metre
Since costs vary with the scope of work, here is a reference range at the Standard tier, before any regional adjustment. In addition, the table shows the same costs in euros and pounds per square metre.
| Room | USD per sq ft | EUR per sq m | GBP per sq m |
|---|---|---|---|
| Kitchen | $128 – $172 | €1,263 – €1,708 | £1,084 – £1,467 |
| Bathroom | $170 – $230 | €1,683 – €2,278 | £1,446 – £1,956 |
| Bedroom | $42 – $57 | €421 – €569 | £361 – £489 |
| Living Room | $38 – $52 | €379 – €512 | £325 – £440 |
| Basement | $51 – $69 | €505 – €683 | £434 – £587 |
| Whole Home | $60 – $80 | €589 – €797 | £506 – £685 |
Euro and pound figures are converted at fixed approximate rates, so treat them as a guide.
Where Your Renovation Budget Goes
For example, in a typical kitchen renovation, cabinetry takes the largest share, often about a third of the total. This is because style, finish and layout have a big effect on price. Countertops and flooring follow, while labor covers demolition, installation and trades such as plumbing and electrical work.
Overall, a clear breakdown helps you see where to cut costs when the estimate is over budget, instead of trimming everything evenly. For background on typical projects, see Wikipedia’s article on home improvement.

Tips for Budgeting a Renovation
Because surprises are common in almost every renovation, a little planning goes a long way. In addition, a few simple habits keep the budget under control.
- Set aside a contingency fund. Plan for 10 to 20% of your budget, since older properties often hide outdated wiring, aging plumbing or water damage that appears only after demolition begins.
- Get several quotes. Because prices for the same job can differ a lot between contractors, ask for at least three.
- Consider an inspection first. Moreover, this is especially useful for older homes, because it can find costly problems before you fix the scope and budget.
- Allow for lead times. Therefore, in busy markets, expect contractors to need longer and charge more.
- Plan the money too. Therefore, try our mortgage calculator or loan calculator to see how a renovation loan affects your monthly budget.

Renovation Calculator FAQs
How accurate is this renovation cost estimate?
This calculator gives a ballpark range based on typical costs per square foot, not a formal quote. However, the real cost depends on your contractor, your materials, local permit fees and any surprises found once work begins. Therefore, treat it as a starting point for budgeting.
How much does a renovation cost per square foot or square metre?
At the Standard tier, a whole home costs about $60 to $80 per square foot, while a kitchen costs about $130 to $170 and a bathroom about $180 to $220. Also, the calculator shows your cost per square foot or square metre once you press Calculate.
How much contingency budget should I set aside?
First, most planners suggest 10 to 20% of your budget. In addition, older homes sit at the higher end, because wiring, plumbing and water damage often appear only after demolition begins.
Can I use this renovation calculator for euros or pounds?
Yes, because you can pick US dollars, euros, pounds, Canadian dollars or Australian dollars. However, the figures are a model converted at fixed approximate rates, so ask local contractors for real prices.
Why do renovation costs vary so much by region?
First, labor rates, material costs and permit fees differ by market. For example, a higher-cost metro area can run 30 to 50% above a lower-cost region, partly because contractors are busier and wait times are longer.
Should I renovate in phases or all at once?
Although phasing makes it easier to budget and to live at home during the work, it can cost more because contractors repeat setup fees. Therefore, a single full renovation is often cheaper if you can manage the disruption.
What is the biggest cost in a kitchen renovation?
Because style drives price, cabinetry is usually the largest share, often about a third of the total. Next come countertops, flooring and labor, so your cabinet style and finish have the biggest effect on the final number.
Disclaimer: First, this calculator gives a general estimate for planning only and is not a contractor quote. However, actual costs depend on your project, location and market conditions, so always confirm with a qualified professional.
