Self-Financing Capacity: How to Calculate the CAF and Why It Matters

Quick answer. Self-financing capacity (CAF) measures the potential cash your business generates over a financial year. It can be computed two ways: from net profit (additive method) or from gross operating surplus (subtractive method). A CAF higher than your annual principal repayments signals a company able to invest without taking on more debt.

Net profit answers a tax question: how much the company earned after tax. Self-financing capacity answers a management question: how much cash the business is genuinely able to generate. The two figures differ because the result includes charges and income that involve no actual cash movement.

A year can show a modest profit while producing a comfortable CAF, simply because depreciation weighs heavily on the income statement without ever leaving the bank account. This is exactly what a lender looks at before granting credit: they want to know whether your activity produces enough resources to repay the principal instalment. The CAF is the central indicator of that repayment capacity, to be read alongside your other management balances.

The CAF does not appear directly in the annual accounts. It is rebuilt from the income statement, which requires correctly identifying so-called non-cash charges and income. To position the CAF within financial analysis, it helps to know how to read your intermediate management balances, of which gross operating surplus is the most common entry point.

Self-financing capacity is the difference between a year's collectable income and its disbursable charges. In other words, it isolates the flows that translate into a real cash inflow or outflow, and strips out everything that is an accounting entry without a banking movement.

Three families of items distort the reading of net profit and must be reworked to obtain the CAF:

• Depreciation and provision allowances: these are non-cash charges that reduce the result without any disbursement. They are added back.
• Provision and depreciation reversals: non-cash income with no collection. They are removed.
• Asset disposal operations: the accounting gain or loss mixes in exceptional items that must be neutralised, since the real flow is the sale price, not the accounting result of the disposal.

The CAF should not be confused with gross operating surplus. The latter measures the profitability of the operating cycle alone, before financial and exceptional items. The CAF, by contrast, includes collectable or disbursable financial and exceptional income and charges. If you hesitate between these notions, our article to understand EBE and EBITDA clarifies the adjustments.

The subtractive method starts from gross operating surplus. It is the most intuitive approach for a business owner because it follows the natural path of financial analysis, from operations to available cash.

The general formula is:

CAF = gross operating surplus + collectable income (excluding disposals) - disbursable charges (excluding disposals)

In practice, you add to the operating surplus the financial and exceptional income that involves a collection (accounts 76 and 77, except disposal proceeds 775 and subsidy portions 777). You subtract the financial and exceptional charges that involve a disbursement (accounts 66 and 67, except the book value of disposed assets 675).

Steps of the subtractive method#

1. Start from the gross operating surplus for the year.
2. Add other collectable operating income and operating expense transfers.
3. Add collectable financial income, then subtract disbursable financial charges.
4. Add collectable exceptional income excluding disposals, then subtract disbursable exceptional charges excluding disposals.
5. Subtract employee profit-sharing and corporate income tax.
6. The resulting balance is the self-financing capacity for the year.

The additive method starts from the net result for the year. It is often faster in practice because the result already appears on the income statement: you simply neutralise the non-cash entries.

The principle is to add back to the result the charges that were not disbursed, and to subtract the income that was not collected.

Both methods reach exactly the same figure. The additive method often serves as a consistency check: if your two calculations diverge, an adjustment has been overlooked, usually a provision reversal or a subsidy portion.

Consider an SME subject to corporate income tax. Here is a simplified case built to illustrate the mechanics.

With a net result of 60,000 € and corporate income tax partly at the reduced rate, the company generates a CAF of 127,000 €, more than double its accounting profit. If it repays 70,000 € of loan principal during the year, its CAF comfortably covers that instalment and leaves 57,000 € to invest or build a reserve.

If the shareholders decide to distribute 30,000 € in dividends, net self-financing drops to 97,000 €. That amount is what truly remains in the company to fund its development. Dividend distribution in a company subject to corporate income tax also bears the flat tax of 31.4% in 2026, a parameter to factor into the trade-off between remuneration and retained earnings.

Sole proprietorships and micro-enterprises. Without corporate income tax and detailed accounting depreciation under the micro regime, the CAF loses much of its operational relevance. Management relies instead on the net cash balance after personal drawings. For a sole proprietorship on the actual regime, the CAF is computed by neutralising the owner's remuneration, which is not a deductible charge.

High-growth companies. A startup may show a negative CAF for several years: disbursable charges exceed collectable income. This is not abnormal in the seed phase, but it requires funding the gap through equity or debt. This is precisely the role of an outsourced CFO who projects the CAF trajectory over three years.

Holding companies. Participation income (dividends from subsidiaries) inflates the holding's CAF, but its recurrence depends on the group's distribution policy. The structural CAF must be distinguished from a CAF inflated by exceptional upstream distributions.

The underestimated risk: confusing CAF with available cash. A high CAF does not mean the money is in the account. The CAF is a capacity, not a bank balance. A company can show a strong CAF while running short of liquidity if its working capital requirement has surged, for instance through higher inventory or trade receivables. To link the CAF to actual movements, the cash flow statement remains the reference tool.

What lenders and authorities look at. The repayment capacity ratio, financial debt divided by CAF, is closely watched by credit institutions. Below three or four years of CAF to repay the debt, the file is generally considered sound. Above that, the company appears over-indebted relative to its ability to generate cash.

Beware overlooked adjustments. The most common error we correct is including disposal proceeds in the additive CAF without removing the book value of the disposed asset. The result is overstated, which inflates the company's real capacity.

In our files, the CAF is the indicator we systematically present before any investment or borrowing decision. A business owner in the services sector recently came to us after a bank refused a loan, even though the income statement showed a decent profit. The analysis revealed a weak CAF: depreciation was thin for lack of recent investment, and financial charges weighed on the result. The banker was not reading a profitability problem, but an inability to generate cash for repayment. Rebuilding the CAF and projecting it over three years allowed the request to be restructured to a sustainable amount.

Our reading is this: the CAF should never be looked at in isolation. It gains meaning when compared to three figures: repayment instalments, working capital requirement, and planned investments. A CAF of 100,000 € is excellent for a company repaying 30,000 € a year with no working capital growth; it is insufficient for one that must fund 120,000 € of principal and a rising working capital requirement.

The classic trade-off pits dividend distribution against self-financing. Distributing rewards the shareholder immediately but reduces internal resources and can weaken a banking file. Retaining strengthens equity and reassures lenders, but ties up the shareholder's cash. This choice is decided in light of your project and personal tax situation, within a forecast balance sheet that quantifies both scenarios. As a firm registered with the Order of Chartered Accountants, this is the type of trade-off we document to secure the owner's decision.

Hayot Expertise advice. Calculate your CAF every year and track its trend over three financial years: a steadily declining CAF is a warning sign well before cash tightens. Always compare it to your loan repayments and your working capital requirement. Rigorous bookkeeping and review ensures your non-cash charges are correctly recorded, a precondition for a reliable CAF.
