A good cash conversion cycle is one that falls within a reasonable range of your industry average and is stable or improving over time – there is no single number that qualifies as “good” for every business.
A 40-day CCC would be excellent for a manufacturer and poor for an online retailer. Context is everything, and the most useful thing you can do is compare your number against the right benchmark and then watch how it moves.
UK Industry Benchmarks
Different business models lock up cash for very different lengths of time. Here are typical cash conversion cycle benchmarks for UK SMEs:
| Industry | Typical CCC (Days) |
|---|---|
| Retail | 15 |
| E-commerce | 17 |
| Professional Services | 23 |
| Construction | 38 |
| Manufacturing | 86 |
Retailers collect cash quickly and often negotiate extended supplier terms. Manufacturers carry significant stock, have longer production cycles, and frequently wait months to get paid. If your business spans sectors, your benchmark will sit somewhere between the two. Use the CCC Calculator to work out your actual number.
The General Rule: Lower Is Better
A shorter CCC means your cash comes back to you faster, with less reliance on overdrafts or loans.
A negative CCC is even possible – it means you collect cash from customers before you have to pay your suppliers. Subscription businesses and some retailers achieve this, but it is not realistic for most B2B companies.
That said, squeezing your CCC by delaying payments to suppliers beyond agreed terms damages relationships. The goal is efficiency, not exploitation.
What Matters More Than the Number: The Trend
A CCC of 50 days is not inherently good or bad. But a CCC that was 35 days last year, 42 days six months ago, and 50 days now tells you something important – your cash cycle is deteriorating, and you need to find out why.
Track your CCC quarterly at a minimum. What you are looking for:
- Improving (getting shorter): Collecting faster, managing stock better, or negotiating smarter supplier terms.
- Stable: Predictable. You can plan around it.
- Deteriorating (getting longer): Cash is trapped for longer. Investigate – customers paying more slowly? Stock building up? Supplier terms tightening?
A business with a CCC of 60 that is trending downward is in a stronger position than one at 40 that is creeping upward.
Red Flags to Watch For
Your CCC is growing faster than your revenue. Sales up 10% but CCC up 25%? Something in your operating cycle is broken – perhaps new customers with longer payment habits, excess stock, or tightening supplier terms.
Your CCC is significantly above your industry average. A few days above the benchmark is normal. Being 50% or more above it suggests a specific problem – perhaps your Days Sales Outstanding is inflated by chronically late payers, or you are carrying dead stock.
Your CCC is volatile quarter to quarter. Wild swings make cash flow planning almost impossible. This usually points to lumpy invoicing, inconsistent collection practices, or seasonal patterns you have not adjusted for.
A Simple Decision Framework
Once you know your CCC and your industry benchmark, use this rough guide:
Within 20% of your industry average: You are in reasonable shape. Focus on maintaining the trend and look for incremental improvements.
20% to 50% above your industry average: There is room for meaningful improvement. Dig into the three components – DSO, DIO, and DPO – to find where the gap is. Usually one component is the main culprit.
More than 50% above your industry average: You likely have a specific, diagnosable problem. It might be a collections issue, a stock management issue, or unfavourable supplier terms. The Cash Conversion Cycle guide walks through how to break down each component and find the bottleneck.
Worked Example
Tom runs an engineering services firm in Sheffield with annual revenue of around £2 million. He calculates his CCC at 58 days. Professional services firms typically sit around 23 days.
At 58 days, Tom is well above the benchmark – more than double. He breaks it down:
- DSO: 52 days – his customers are paying nearly a month late
- DIO: 12 days – reasonable for a services firm with limited stock
- DPO: 6 days – he is paying his suppliers almost immediately
The diagnosis is clear: slow-paying customers and very fast supplier payments are the problem. Tom could reduce his DSO through better invoicing and collection practices, and negotiate slightly longer supplier terms to give himself breathing room.
The Bottom Line
There is no magic number for a good cash conversion cycle. The practical framework is: know your industry benchmark, track the trend, and investigate if you are significantly above average or moving in the wrong direction. Start with the CCC Calculator – once you have the number, you have something to manage.
