About the Price per Square Foot Calculator
Price per square foot is the quickest way to compare homes, rentals, office space and flooring quotes of different sizes. Enter the price and the area in square feet or square metres to get the price per square foot and per square metre, then compare up to two listings side by side to see which is better value.
How to use it
- Enter the price and area.
- Choose square feet or square metres.
- Add a second listing to compare.
Tips and good to know
- One square metre is exactly 10.7639 square feet.
- Compare like with like — finished living area, not lot size.
- A lower price per square foot isn't always better if the location or condition differs.
- For flooring, add 5–10% to the area for cutting waste.
About money & business tools
Financial calculators are only useful if you understand the formula behind them. Each calculator on this page shows its working: the inputs it uses, the standard formula it applies, and what the result does and does not include. A mortgage figure that ignores property tax, or an ROI that ignores time, can be technically correct and still misleading.
These calculators are educational. They use widely published formulas — the same ones in finance textbooks and bank disclosures — but they cannot know your local taxes, fees or lender terms. Use them to understand the shape of a decision and to compare options, then confirm the final numbers with the institution or a qualified adviser. Nothing you enter is saved or sent anywhere.
Two habits make any calculator more useful. First, change one input at a time and watch how the result moves — that shows you which assumption actually drives the decision, whether it is the interest rate, the term or the price. Second, run a pessimistic and an optimistic scenario rather than a single 'expected' one; real rates, returns and costs rarely stay fixed for years. All figures are shown in whatever currency you are using, because the formulas are the same in dollars, euros or Icelandic krónur. Rounding is applied only for display, so the underlying maths stays precise.

How we build and test our free tools
Every tool in this collection is built and tested by The Curator team. Before a tool is published we check it against known reference results — textbook loan schedules, standard test vectors for hashes, sample files for conversions — and we re-check it whenever browsers change. Each page explains the method so you can verify the answer yourself rather than take it on trust.
The tools run as JavaScript inside your browser tab. When you choose a file, your browser reads it from your disk into memory; the tool processes it and gives you the result as a download. No copy is sent to us or to anyone else, and nothing is kept after you close the tab. That is why these tools are safe for personal documents, and why they keep working on a slow or interrupted connection once the page has loaded.
The collection is free because it is supported by advertising on these guide pages. We never charge for a tool, never add watermarks and never sell what you type. If something doesn't work as described, or you would like a tool we don't have yet, please contact us — new tools are added in regular batches based on what readers ask for.
