Weekly to Monthly Rent Converter

Many UK property listings advertise rent weekly (PW), while most tenants budget monthly (PCM). This calculator simplifies conversions so you can compare properties on a like-for-like basis.

Example:

If a flat is listed at £300 PW, you can convert this to approximately £1,300 PCM.
(Formula: weekly rent × 52 ÷ 12)
