How to Read a Profit and Loss Statement UK
A profit and loss (P&L) statement shows a business’s revenue, costs, and profit over a specific period. Understanding how to read a P&L is the foundation of commercial literacy for any UK SME owner.
The Formula
P&L Structure: Revenue − COGS = Gross Profit → Gross Profit − Overheads = Operating Profit → Operating Profit − Interest − Tax = Net Profit
Worked Example — UK SME
A UK P&L: Revenue £420,000. COGS £268,800. Gross profit £151,200 (36%). Overheads £126,600. Operating profit £24,600. Interest £4,200. Tax £5,100. Net profit £15,300 (3.6%).
UK Benchmark
📊 Key ratios to extract: gross margin % (compare to sector benchmark), overhead ratio (overheads ÷ revenue), net margin % (minimum 3–4% for any viable UK SME).
Common Questions
What is the difference between a P&L and a balance sheet?
A P&L shows performance over a period. A balance sheet shows financial position at a single point in time. Both are needed for a complete financial picture.
What should I look for first when reading a P&L?
Start with gross margin — is it within sector benchmark? Then check the overhead ratio. Then net margin. Finally check whether the trend is improving or deteriorating.
How often should a UK SME review their P&L?
Monthly at minimum. Weekly for businesses with thin margins or tight cashflow. Reviewing annually is far too infrequent to manage effectively.
