Direct answer

The result is the average calendar-month equivalent, not the 4-week amount.

monthly = weekly rent x 365 / 7 / 12

How this calculator works

monthly = weekly rent x 365 / 7 / 12. The result is the average calendar-month equivalent, not the 4-week amount. The result keeps the period math consistent, so a weekly, 14-day, 28-day, monthly, or annual amount can be compared on the same basis.

When to use this page

Use this when a UK listing is quoted weekly and you need to compare it with a monthly budget, another PCM listing, or a rent cap before deciding whether to enquire.

What this result does not include

The result converts rent only. Utilities, deposits, parking, pet rent, service charges, insurance, move-in fees, proration, and lease-specific payment rules are not included unless you add them to the rent amount yourself.

How to read the comparison

Use the converted amount for the budget period you actually plan with, then keep the original listing period visible so you do not lose track of how rent is collected. A calendar-month result is best for monthly bills, while a weekly, fortnightly, or 4-week result is better for matching a payment cycle.

Calendar month vs payment cycle

A calendar month is not always the same as a repeated payment cycle. Weekly, fortnightly, biweekly, and 4-week rent should be annualized before comparing with monthly rent.

Costs that can change the decision

If two listings are close, utilities, deposits, parking, pet rent, service charges, internet, and move-in costs can matter more than the converted rent difference.

Worked examples

UK room search

A weekly room listing can look cheaper than the PCM comparison. Convert it before comparing with monthly bills or salary.

4-week trap

Multiplying by 4 only covers 28 days, so it understates the true monthly equivalent for PW listings.

Calculations use a 365-day year, 7-day weeks, 14-day fortnightly or biweekly periods, 28-day four-week periods, and 365 divided by 12 days for a calendar month.
