Direct answer
Monthly rent is multiplied by 12 to get annual rent, then divided into 7-day weekly periods.
How this calculator works
PW = PCM x 12 / 365 x 7. Monthly rent is multiplied by 12 to get annual rent, then divided into 7-day weekly periods. 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-style listing uses PW, PCM, or 4-weekly wording and you need one clear monthly or weekly comparison.
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.
PCM to an average PW amount
PCM means per calendar month and PW means per week. The reverse formula is monthly rent x 12 x 7 / 365, which preserves the annual rent before finding a 7-day equivalent.
Why dividing by 4 is inaccurate
Dividing monthly rent by 4 treats a calendar month as exactly 28 days. The result here is an average weekly equivalent based on the full annual rent.
