Running a pharmacy is more than just dispensing medication. Managing finances, cash flow, dealing with NHS reimbursements and keeping supplier payments in check is a constant challenge. Financial ratios help pharmacy owners measure profitability, liquidity, efficiency and financial stability with numbers.
Ignoring these ratios leads to poor decisions, unmanageable debt and unstable operations. Pharmacy owners who track financial metrics can maximise profitability, reduce cash flow gaps and make informed business decisions. This guide covers the most important financial ratios for pharmacy businesses.
1️⃣ Gross profit margin shows how well a pharmacy prices and controls costs.
2️⃣ Inventory turnover ratio measures stock movement and risk of expired stock.
3️⃣ Current ratio ensures a pharmacy can cover short-term liabilities.
4️⃣ Debt-to-equity ratio shows financial leverage and risk.
5️⃣ NHS to private revenue ratio helps pharmacies assess income dependence on NHS contracts.
6️⃣ Operating cash flow ratio measures if a pharmacy generates enough cash from operations to sustain itself.

What are the Most Important Profitability Ratios for Pharmacies?
Pharmacies need high profitability margins to be sustainable. Profitability ratios measure how well a pharmacy converts sales into profit. Understanding these profitability ratios like Gross profit margin, operating profit margin and net profit margin will help pharmacy owners increase profitability and reduce operating costs.
Below we break down some key profitability ratios.
Gross Profit Margin
Formula: (Turnover – Cost of Goods Sold) / Turnover
- Why It Matters: This Gross Profit Margin ratio shows how well a pharmacy sells prescription and over-the-counter (OTC) products. A healthy margin is between 20-40% in retail pharmacies.
- Industry Benchmark: According to a study by the National Pharmacy Association (NPA), average UK pharmacy gross margins are 28-33% depending on the mix of NHS and private sales.
Net Profit Margin
Formula: Net Income / Turnover
- Why It Matters: It shows the pharmacy’s actual profit after all expenses.
- Real-World Example: A pharmacy with £500,000 turnover and £75,000 net income has a 15% net profit margin. If the margin drops below 10% the business may not be able to cover costs.
NHS Income / Private Sales Revenue
- Why It Matters: Many UK pharmacies rely on NHS prescriptions but a diversified revenue stream reduces risk.
- Industry Benchmark: An NPA report shows 80% of UK pharmacy revenue comes from NHS prescriptions. A higher ratio means cash flow depends on government reimbursements which can be delayed.
How Do Liquidity Ratios Prevent Cash Flow Issues?
Liquidity ratios measure a pharmacy’s ability to meet financial obligations on time. Poor liquidity causes supplier payment issues and stock shortages.
Current Ratio
Formula: Current Assets / Current Liabilities
- Why It Matters: A ratio above 1.2 means a pharmacy can cover short term liabilities. Below 1.0 means cash shortages.
- Pharmacy Example: A pharmacy with £200,000 in current assets and £150,000 in liabilities has a 1.33 current ratio, it can meet its obligations comfortably.
Operating Cash Flow Ratio
Formula: Operating Cash Flow / Current Liabilities
- Why It Matters: It shows if pharmacy operations generates enough cash to cover debts.
- Industry Data: A study by the Royal Pharmaceutical Society found 40% of independent UK pharmacies struggle with cash flow due to NHS payment delays.
How Do Efficiency Ratios Improve Stock Management?
Pharmacies need to balance inventory levels to avoid stock-outs and medication wastage. These ratios measure how well stock and receivables are managed.
Inventory Turnover Ratio
Formula: Cost of Goods Sold / Average Inventory
- Why It Matters: Low turnover means excess stock, increasing the risk of expired stock.
- Industry Standard: UK pharmacies have an inventory turnover ratio of 6-10, meaning stock is replenished every 1-2 months.
- Actionable Tip: Below 5 means the pharmacy is holding excess stock, impacting cash flow.
Receivables Turnover Ratio
Formula: Total Sales / Average Accounts Receivable
- Why It Matters: It measures how efficiently NHS and private payments are collected.
- Industry Insight: NHS reimbursement delays can extend accounts receivable period to 60-90 days. Higher turnover means faster collection.
Cash flow tracking and optimising will help you gain operational freedom. By doing this, you can expand your business faster than you expect.

How Do Debt Ratios Manage Pharmacy Loans and Financing?
Pharmacies take loans for business expansion, stock purchasing or equipment investment. These ratios indicate financial health.
Debt-to-Equity Ratio
Formula: Total Debt / Total Equity
- Why It Matters: Above 2.0 means high debt reliance, higher financial risk.
- Industry Benchmark: UK pharmacy industry has a debt-to-equity ratio of 1.5, moderate financial leverage is common.
Interest Coverage Ratio
Formula: EBIT / Interest Expense
- Why It Matters: It shows if the pharmacy can afford its debt interest payments.
- Industry Standard: Below 1.5 means difficulty in paying interest, higher bankruptcy risk.
How Financial Tracking Saves You Money When Hiring Locums
Financial tracking helps pharmacy owners manage locum costs and cut unnecessary overheads. Here’s how:
1️⃣ Staffing Schedules – By looking at labour costs and sales trends financial tracking helps you know your peak and quiet hours. So you only call in locums when needed and don’t over staff.
2️⃣ Cost vs. Revenue – Tracking key financial ratios like wage-to-revenue ratio means your locum costs are in line with your pharmacy’s income. If costs are too high you can make adjustments.
3️⃣ Locum vs. perm staff – Regular financial reviews help you determine if hiring full time pharmacists would be more cost effective than using locums.
4️⃣ Better Rates – Knowing your locum spend over time means you can negotiate better rates with locum agencies or direct hires and get competitive rates without overspending.
5️⃣ No Unnecessary Overtime – Financial tracking helps prevent excessive locum hours, so shifts are allocated appropriately to match workload.
By keeping an eye on your financial reports you can make data driven staffing decisions and save on locum costs while keeping your pharmacy running smoothly.

Hypothetical Case Study: Controlling Staff Costs Through Ratio Analysis
John owns a small pharmacy and struggles with high staff costs. He notices that payroll expenses take up a large portion of his revenue but isn’t sure how to measure the impact. Using the Staff Cost Ratio (Total Staff Costs / Total Revenue), he finds that his staff costs are 45% of total revenue, higher than the industry average of 30%.
Actionable Insight: By adjusting staff schedules, reducing overtime and automating tasks like inventory management, John lowers his staff cost ratio to 35% within three months without reducing service quality.
How Monitoring Financials Boosts NHS Reimbursements, Cash Flow and Supplier Discounts
By keeping on top of financials pharmacies can speed up NHS reimbursements, cash flow and supplier discounts – a more profitable and well managed business.

Faster NHS Reimbursement Monitoring
Monitoring financials allows pharmacies to track NHS claims and payments in real time. By keeping accurate records of submitted claims, pending payments and discrepancies, pharmacies can ensure payments are made on time and avoid cash flow gaps. This reduces the risk of financial shortfalls and maintains a steady income.
Cash Flow Benefits
By monitoring financials pharmacy owners can see what’s coming in from NHS reimbursements and plan for expenses and working capital. This means day to day operations run smoothly without financial stress, no late payments, overdrafts or emergency borrowing.
Early Settlement Supplier Discounts
With cash flow visibility pharmacies can take advantage of early settlement discounts from suppliers. By scheduling payments when the cash is available, owners can reduce procurement costs and increase profits.
Better Working Capital Management
Monitoring financials allows pharmacies to maintain the right balance between receivables, payables and inventory. By understanding cash flow cycles and optimising supplier payments pharmacies can ensure they have the liquidity to invest in stock, pay staff and cover operational costs efficiently.
