Investment, profit and cash flow
Investment, Profit and Cash Flow
When a business makes a significant capital investment — purchasing machinery, acquiring a building, or upgrading its technology infrastructure — the financial effects ripple through three different statements in three different ways and over three different time horizons. Understanding how investment affects cash flow, profit, and the balance sheet simultaneously — and why these effects diverge — is one of the more demanding analytical skills in IBDP Business Management.
The immediate cash flow impact
Capital investment requires cash. When a business purchases a non-current asset for cash, the full purchase price leaves the bank account immediately — producing a large, one-off cash outflow in the cash flow forecast for that period. If the asset costs £120,000, the cash position falls by £120,000 in the month of purchase, regardless of how long the asset will be used or how much revenue it will generate.
If the asset is financed by a loan, the picture changes: the loan proceeds arrive as a cash inflow, partly or wholly offsetting the purchase outflow. However, monthly loan repayments then appear as ongoing cash outflows in subsequent periods — smaller and spread over time, but still reducing cash flow throughout the loan term.
The gradual profit impact
In the profit and loss account, the £120,000 investment does not appear as a single expense. Instead, it is capitalised — recorded as a non-current asset on the balance sheet — and its cost is spread over the asset's useful economic life through annual depreciation charges. If the asset has a useful life of 8 years and zero residual value, only £15,000 appears as a depreciation expense each year in the income statement.
This means the profit impact of the investment is gradual and spread: £15,000 per year for 8 years, rather than £120,000 in year one. In year one, cash flow falls by £120,000 (or the loan proceeds arrive followed by monthly repayments), whilst profit falls by only £15,000 (the first year's depreciation). In years 2 through 8, cash flow is affected by loan repayments whilst profit continues to absorb £15,000 of annual depreciation — even though no further cash outflow relating to the original purchase occurs.
The balance sheet impact
On the balance sheet, the investment immediately creates a non-current asset recorded at cost (£120,000). Each year, accumulated depreciation is deducted, reducing the net book value (NBV) of the asset. By year 8, the NBV reaches zero (or the residual value). The balance sheet therefore shows the declining value of the asset over its life, whilst equity is reduced each year by the depreciation charge (which reduces retained profit).
If the asset was financed by a loan, the loan appears as a liability on the balance sheet — non-current in the early years, shifting progressively to current as repayments reduce the outstanding balance and the loan term shortens.
Northmoor Joinery Ltd purchases a new CNC router for £96,000 cash. The machine has a useful life of 8 years and a residual value of £8,000, depreciated using the straight-line method.
[ ext{Annual depreciation} = frac{£96{,}000 - £8{,}000}{8} = £11{,}000 ext{ per year} ]The table below summarises how the investment flows through the three financial statements:
| Statement | Year of purchase | Years 2-8 |
|---|---|---|
| Cash flow forecast | £96,000 cash outflow (immediate, in month of purchase) | No further cash impact from original purchase |
| Profit and loss account | £11,000 depreciation expense (first year only) | £11,000 depreciation expense each year |
| Balance sheet | Non-current asset at NBV £85,000 (£96,000 - £11,000) | NBV falls by £11,000 each year; reaches £8,000 in year 8 |
The divergence is stark: in year one, Northmoor's bank balance falls by £96,000 whilst its reported profit falls by only £11,000. A manager reading only the income statement might conclude the investment had a modest financial impact; a manager reading only the cash flow statement would see a very different picture. Both are correct — they measure different things over different time horizons.
By year 5, the machine has an NBV of:
[ ext{NBV (year 5)} = £96{,}000 - (5 imes £11{,}000) = £96{,}000 - £55{,}000 = £41{,}000 ]No further cash has been paid since the original purchase, but the income statement has absorbed £55,000 of depreciation charges across five years, reducing cumulative profit by that amount. The balance sheet records the remaining economic value of the asset.
Investment financed by a loan
When the same £96,000 investment is financed by a five-year loan at a fixed annual interest rate, the cash flow pattern changes significantly:
- Year of purchase: £96,000 cash inflow (loan proceeds) and £96,000 cash outflow (asset purchase) — net cash flow impact of zero in the purchase month, though this masks significant future obligations.
- Years 1-5: regular loan repayments (principal plus interest) appear as cash outflows each month. Interest also appears as a profit and loss expense, reducing PBIT. Capital repayments do not affect profit — they are a balance sheet transaction (reducing the loan liability and cash simultaneously).
- After year 5: no further loan repayments — but depreciation continues until year 8. The income statement still absorbs £11,000 per year of depreciation long after the cash obligations have ended.
This pattern illustrates one of the most important principles in business finance: the timing of cash obligations and accounting expenses are governed by different rules and rarely coincide.
Key Takeaways
- Capital investment produces an immediate, large cash outflow (or loan-funded inflow followed by repayments) but only a gradual, annual profit impact through depreciation.
- The depreciation charge reduces profit each year by an equal amount (straight-line) or declining amount (reducing balance) — but involves no further cash movement after the initial purchase.
- The balance sheet records the non-current asset at net book value (cost minus accumulated depreciation), falling each year until it reaches residual value.
- Loan-financed investment produces capital repayments (balance sheet transactions) and interest payments (income statement expenses) as separate ongoing cash outflows.
- Profit, cash flow, and balance sheet values all tell a different part of the investment story — they must be read together for a complete picture.
