What it means
Capital funding pays for things that will generate returns over years: a new plant, a fleet, an acquisition or a major systems programme. Because the benefits are long-term, the funding is expected to be long-term too, which is why a five year loan or a share issue suits far better than an overdraft.
Equity funding requires no repayment and no interest, which makes it safer in a downturn, but it dilutes ownership and it is the more expensive source overall. Investors accept the risk of losing everything and therefore demand a higher return than a lender does, typically expressed as a required rate somewhere well above the interest rate on debt.
Debt funding is cheaper for two reasons: lenders sit ahead of shareholders if things go wrong, and interest is normally deductible against tax while dividends are not. The catch is that repayments are contractual, so debt raises the risk of financial distress in a bad year.
Most businesses therefore blend the two and measure the result as a weighted average cost of capital. That single percentage becomes the hurdle rate that any new project must beat, because a project earning less than the cost of the money used to fund it destroys value however impressive its revenue looks.
The right mix shifts with the maturity of the business. Early-stage companies with unpredictable cash flows lean towards equity because they cannot promise the fixed repayments debt requires, while established businesses with steady cash flows take on more debt precisely because they can.
In practice
Real-world examples.
Example
A vineyard funds a $3.2m bottling plant with a 10 year mortgage over the land and buildings, matching a long-lived asset to long-dated funding. The repayment schedule is deliberately aligned with the harvest cycle so that instalments fall after the main selling season.
Example
A medical devices startup raises $8m of equity rather than debt because it has no revenue and cannot service repayments. The founders accept dilution from 100% to 62% ownership as the cost of funding four more years of development.
Example
A logistics group funds 40 new trailers through asset finance secured on the trailers themselves. Because the lender holds security over the equipment, the rate is 2 percentage points lower than the group's unsecured facility.
Formula
Calculation
Weighted Average Cost of Capital = (Equity Weight x Cost of Equity) + (Debt Weight x After-Tax Cost of Debt)
A manufacturer needs $5,000,000 to build a second production facility. It raises $2,000,000 from investors and borrows $3,000,000 from a bank.
Equity weight: $2,000,000 / $5,000,000 = 40%
Debt weight: $3,000,000 / $5,000,000 = 60%
The investors require a 12% return. The bank charges 7% and the company pays tax at 25%, so the after-tax cost of the debt is:
After-tax cost of debt: 7% x (1 - 0.25) = 5.25%
Weighted average cost of capital: (0.40 x 12%) + (0.60 x 5.25%) = 4.8% + 3.15% = 7.95%
In cash terms that is $240,000 a year expected by investors plus $157,500 of after-tax interest, or $397,500 in total. The new facility must generate at least that much additional annual return before it adds any value to the business.Case study
Seen in the real world.
The following is an illustrative and fictional example. Ravensworth Foods needed $4m to automate its packing hall and, wanting to avoid dilution, funded the whole amount with a five year bank loan repayable in equal instalments.
The economics of the project were sound: the automation saved $900,000 a year in labour and waste. The problem was the repayment profile. Principal and interest came to roughly $960,000 a year, and the savings only began to arrive nine months after installation, so Ravensworth spent almost a year servicing full repayments on a benefit it was not yet receiving. It came close to breaching a covenant on a project that was actually working.
A restructured package of $2.5m of debt with an interest-only first year plus $1.5m of equity from an existing shareholder would have matched the cash flows far better at a slightly higher blended cost. This illustrative case makes the point that capital funding decisions are about timing and shape as much as headline cost.
Watch out
Common mistakes.
- Funding long-term assets with short-term facilities. Buying equipment on an overdraft leaves the business exposed if the facility is withdrawn before the asset has paid for itself.
- Treating equity as free money. It carries no interest but it is the most expensive source of capital, because investors expect a return well above what a lender would accept.
- Ignoring the cost of capital when appraising projects. A project returning 6% funded by capital costing 8% destroys value even though it looks profitable in isolation.
Questions
People also ask.
What is the difference between capital funding and working capital?
Capital funding buys long-term assets and projects, while working capital finances the day-to-day gap between paying suppliers and being paid by customers.
How much debt is too much?
It depends on how predictable the cash flows are, but many lenders start to resist when total debt exceeds three times annual earnings before interest, tax, depreciation and amortisation.
Do grants count as capital funding?
Yes where they fund long-term assets, and they are the cheapest source of all since they carry neither interest nor dilution, though they usually come with conditions on use.
