Direct answer
This page uses the 365-day method rather than a loose 52/12 shortcut, so the result matches the sitewide rent model.
How this calculator works
PCM = PW x 365 / 7 / 12. This page uses the 365-day method rather than a loose 52/12 shortcut, so the result matches the sitewide rent model. 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 you need to move between UK-style PW and PCM wording and keep the annual rent consistent. It helps compare room listings, flat listings, and monthly salary planning on the same basis.
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
