Rent Value Calculator

About this tool

One flat is cheap but far, the other is close but expensive, and rent alone cannot settle it. Pricing the commute at your hourly rate and folding in floor area puts both options on the same sheet.

A 60 m² flat at 3,200 a month with a 45-minute one-way commute, 22 days and a 100 hourly rate carries 3,300 in commute cost; with 300 of fees the all-in figure is 6,800 and commuting is nearly half of it. A 4,200 flat with a 15-minute commute can end up cheaper overall.

What it does

• Three inputsRent, area and commute entered separately Every number shown here maps to a field on the form, so changing one value recomputes the rest. The units are printed next to each input, which saves most of the usual mistakes.
• Time pricedCommute converted at your hourly rate The main figures sit at the top of the result panel and the breakdown sits below it, so you can read the conclusion first and audit the steps afterwards. Nothing you type leaves the browser.
• Fees includedExtra fees included in the total All arithmetic runs locally in the page. There is no request to a server, no account, and no saved history once the tab is closed. Use the example button if you want a set of values that is known to work.
• Per square metreShows all-in cost per square metre Intermediate quantities are kept in the detail table. When a total looks wrong, tracing back through those rows is much quicker than staring at the headline number alone.
• Commute shareCommute share shown on its own The formula is written out in the notes rather than hidden behind a label, so you can check it against a spreadsheet or a textbook. Values are rounded only for display.
• Side-by-sideA score makes two flats comparable Inputs are validated before any calculation starts. Empty or impossible values produce a short explanation instead of a zero, a NaN, or a made-up answer.

How to use it

1. Start by filling inenter monthly rent and floor area The main figures sit at the top of the result panel and the breakdown sits below it, so you can read the conclusion first and audit the steps afterwards. Nothing you type leaves the browser.
2. Next, setenter one-way commute minutes All arithmetic runs locally in the page. There is no request to a server, no account, and no saved history once the tab is closed. Use the example button if you want a set of values that is known to work.
3. Then pressenter commuting days and hourly rate Intermediate quantities are kept in the detail table. When a total looks wrong, tracing back through those rows is much quicker than staring at the headline number alone.
4. Read theenter other monthly fees The formula is written out in the notes rather than hidden behind a label, so you can check it against a spreadsheet or a textbook. Values are rounded only for display.
5. Finally, usepress Calculate, then enter a second flat to compare Inputs are validated before any calculation starts. Empty or impossible values produce a short explanation instead of a zero, a NaN, or a made-up answer.

Things to keep in mind

• One-way basiscommute minutes are one-way All arithmetic runs locally in the page. There is no request to a server, no account, and no saved history once the tab is closed. Use the example button if you want a set of values that is known to work.
• Zero ratea zero hourly rate removes commute cost Intermediate quantities are kept in the detail table. When a total looks wrong, tracing back through those rows is much quicker than staring at the headline number alone.
• Excluded factorsthe score ignores catchments and aspect The formula is written out in the notes rather than hidden behind a label, so you can check it against a spreadsheet or a textbook. Values are rounded only for display.
• Zero feesenter 0 when there are no extra fees Inputs are validated before any calculation starts. Empty or impossible values produce a short explanation instead of a zero, a NaN, or a made-up answer.
• Round tripthe round trip is twice the one-way figure Every number shown here maps to a field on the form, so changing one value recomputes the rest. The units are printed next to each input, which saves most of the usual mistakes.
