Divide the entered total price or rent by positive measured area. Use one currency and area definition. Rent is labeled per month or year; the amounts differ by a factor of 12. No exchange rate or appraisal is inferred.
Reverse price and area relationships
Divide the entered total price or rent by positive measured area. Use one currency and area definition. Rent is labeled per month or year; the amounts differ by a factor of 12. No exchange rate or appraisal is inferred.
Multiply unit price by area for total price/rent. Divide the total by positive unit price for area. Keep currency, area unit and rent period consistent. The inactive solved field is not an additional assumption.
One ft² equals exactly 0.09290304 m². Switching units converts the existing primary and comparison measurements and preserves total price. The inverse factor is not the rounded 10.7639. Intermediate ratios retain full floating precision.
Read the equation beside the chosen result rather than assuming every view solves for a unit price. A calculated total or area uses the other two active entries and is identified as calculated when it becomes the recorded measurement. Review the alternative-unit result without replacing a verified living-area measurement with gross building area. Extra decimal places reveal small nonzero ratios; they do not improve the accuracy of the original measurement or make an asking price a verified transaction price.
Same-basis comparisons and their limits
No. It is the lowest entered same-basis ratio, not an appraisal or recommendation. Check location, condition, ownership rights and charges separately. The median uses only valid included same-basis listings; it is not a market benchmark.
Use the actual listing total. For a detached home, condo or townhouse, check that property's ownership and transaction documents. The calculator cannot allocate land, structures, common interests or HOA fees, or infer them from property type or unit price.
Manual notes do not change the calculation.
Give each listing a useful optional name and record the area basis and rent period from its source. An excluded row remains visible so you can understand why it does not affect the selected baseline. A zero baseline has no meaningful percentage difference, even though a zero-price property can have a valid arithmetic ratio. Use the relationship chart to inspect the entered area and total price together, and compare its numeric coordinates with the table. Its reference line is derived from your selected comparable baseline and does not predict the price of another property.
Saved scenario and sharing
Names and notes are optional, and no address is required for the calculation. A fresh visit does not remember a financial scenario automatically. Choose Remember only if you want this device to retain the current scenario and subsequent edits. Known earlier saved records are interpreted by their schema and kept literally; review newly declared currency, rent period and measured-area assumptions instead of guessing what an old value intended. Forget removes the calculator’s owned saved records. Reset clears a personal saved scenario, while a shared visit preserves the recipient’s existing personal record. Each Share or Embed opening starts with a clean link, and including details requires reviewing the current scenario and inactive purchase or rent drafts. Changes to inputs return that preview to a clean link before another decision. Anyone receiving a full link can read its values and notes. Copy and CSV also contain the complete current comparison and its entered assumptions, so consider where those messages and files will be stored.
