PCM (PCM)
FinancialThe standard way of expressing rental prices in the UK, indicating the monthly rent amount payable
PCM stands for Per Calendar Month, the standard way of expressing rental prices in the UK. When a property is listed at "GBP1,500 PCM", the rent is GBP1,500 monthly regardless of the number of days. Average UK rent reached GBP1,366 PCM in November 2025. To convert weekly rent to PCM, multiply by 52 and divide by 12; affordability assessments typically require tenant income of 2.5-3x annual rent.
Why PCM is Used
Consistency:
- Regardless of how many days in the month
- Same amount every month
- Easy to budget and plan
Industry standard:
- All listings use PCM
- Mortgage calculations based on monthly rent
- Comparisons straightforward
PCM vs Other Periods
| Period | Calculation | Use Case |
|---|---|---|
| PCM | Fixed monthly amount | Standard rentals |
| PW (Per Week) | Weekly amount x 52 ÷ 12 | Some HMOs, student lets |
| PA (Per Annum) | Annual amount | Commercial, some high-end |
Calculating Equivalents
PCM to annual: Monthly rent × 12 = Annual rent £1,500 × 12 = £18,000 PA
Weekly to PCM: Weekly rent × 52 ÷ 12 = Monthly rent £350 × 52 ÷ 12 = £1,517 PCM
PCM to weekly: Monthly rent × 12 ÷ 52 = Weekly rent £1,500 × 12 ÷ 52 = £346 PW
Daily Rate Calculations
When calculating part-month rent:
Method 1: Monthly rent ÷ days in month £1,500 ÷ 30 = £50/day
Method 2: Annual rent ÷ 365 £18,000 ÷ 365 = £49.32/day
Different methods yield slightly different results - clarify in tenancy agreement.
For Letting Agents
