You can almost predict the moment.
The finance report is presented.
The surplus is mentioned.
The figures look reasonable.
And then someone says something that reveals a deeper tension.
“If we’ve made a surplus… why does it still feel tight?”
Or, “We’ve got money in the bank — so why are we talking about risk?”
It’s a fair question.
In fact, it’s often the right question.
Because this is where two different ideas — surplus and cashflow — quietly get tangled.
And when they do, board conversations become less clear than they should be.
What Surplus Actually Tells You
In simple terms, a surplus means:
Income recognised in the year was higher than expenditure recognised in the year. That’s it.
It tells you something about performance over a period of time.
It does not tell you:
- How much cash is sitting in the bank today
- Whether payroll will clear next month
- Whether that surplus is free to use
A surplus is an accounting outcome.
It is not automatically spare money.
That distinction is small on paper, but significant in practice.
What Cashflow Tells You
Cashflow answers a different question:
How much money is actually moving in and out of the bank, and when?
- It’s about timing.
- It’s about liquidity.
- It’s about whether you can meet your obligations as they fall due.
You can have a surplus and still experience cash pressure.
You can have a deficit and still have healthy cash reserves.
You can have a large bank balance, but very little of it available to spend.
These are not contradictions.
They are simply different lenses.
A Scenario That Happens More Often Than People Realise
Imagine a charity receives a £100,000 grant towards the end of the financial year to deliver a project over the next 12 months.
The cash arrives.
But under accounting rules, that income is recognised over the life of the project.
So the accounts might show:
Income recognised this year: £25,000
Expenditure incurred this year: £20,000
Surplus: £5,000
On paper, the charity made a surplus.
But the £100,000 received is already committed to staff salaries, delivery costs and overheads for the coming year.
The surplus does not mean flexibility.
It reflects how income and expenditure are recognised; not how much is available.
The Bank Balance Trap
Now look at it from another angle.
The bank account shows £120,000.
That sounds reassuring.
But perhaps:
£90,000 is restricted for a specific project.
£20,000 has been designated by trustees for future investment.
£10,000 is unrestricted and available.
Suddenly the conversation changes.
Trustees are not responsible for the headline total.
They are responsible for understanding what can actually be used.
Availability matters more than appearance.
Why This Confusion Persists
Partly, it’s language.
“Surplus” sounds like profit. It sounds like extra.
But in charity accounting, it simply describes a relationship between income and expenditure in a reporting period.
Partly, it’s psychology.
A bank balance feels concrete. It feels safe.
And partly, it’s because boards are often shown year-to-date figures without a clear cashflow forecast.
Without a forward-looking view, timing risks remain invisible; until they aren’t.
Where the Real Risk Sits
This isn’t about technical detail for its own sake.
When surplus and cashflow are used interchangeably, decisions can drift.
Spending may be approved because the accounts look positive.
Cash pressures may be missed because the overall result feels comfortable.
Reserves may be discussed without clarity about what is genuinely free.
As trustees, you don’t need to become accountants.
But you do need to understand the difference between:
Did we generate more income than expenditure this year?
And
Can we meet our commitments in the months ahead?
Those are separate questions.
Both matter.
A Simple Way to Frame It
If you are explaining this at board level, it can be as simple as saying:
The surplus tells us about performance over the year.
Cashflow tells us about timing and liquidity.
They answer different questions.
That clarity alone can steady a conversation.
A Question Worth Pausing On
Have you ever heard “we made a surplus” and still felt uneasy?
That instinct is often pointing to something real.
Surplus answers: Did income exceed expenditure this year?
Cashflow answers: Can we pay our bills when they fall due?
They are connected, but not interchangeable.
And understanding that difference is one of the simplest ways trustees strengthen oversight without needing to dive into technical detail.
