Debt vs. Equity: Which Kind of Money Should Fund Your Business?

Two kinds of money

Debt is a loan. You keep full ownership, you pay interest, and the money has to come back on a schedule whether the business does well or not. The lender's upside is capped at the interest; they don't care if you become enormous as long as you pay.

Equity is ownership sold for cash. There's nothing to repay and no monthly payment. In exchange the investor owns a share of the company, and of every dollar of value it creates, for as long as they hold it. With equity financing you're taking on a partner.

The same $200,000, raised two ways

An owner needs $200,000 to open a second location. Option one is a five-year loan at 9%. The payment is about $4,150 a month, and the loan costs roughly $49,100 in interest over its life.

Option two is selling 25% of the company to an investor for $200,000, which values the whole business at $800,000 after the money goes in.

Now fast-forward five years. If the business is worth $3 million, the investor's 25% is worth $750,000. The equity cost the owner $750,000 of value, against $49,100 of interest for the loan. If instead the business fails, the loan still has to be repaid, quite possibly from the owner's personal assets, while the equity investor simply loses alongside the owner.

Equity is expensive when things go well and cheap when they go badly. Debt is the reverse. That single sentence settles more financing decisions than any other.

What each asks of the business

Debt needs steady cash flow from the first month, because the payments start right away. It suits businesses with predictable earnings and, ideally, assets a lender can take as collateral: a profitable restaurant buying equipment, a service company with long-term contracts.

Equity suits businesses that will lose money for a while chasing something much bigger, which is why startups rely on it. A company burning cash to build software can't make loan payments, and an investor who owns part of it doesn't need them. Venture capital funds work on the assumption that most of their investments will disappoint and a few will return many times their cost, so they only back companies that could plausibly become very large.

Control and the fine print

A lender doesn't vote. As long as you pay and keep your covenants, the business is yours to run. The price of that independence is risk: personal guarantees and collateral mean a bad outcome can reach past the business to you.

An equity investor usually gets rights along with the shares: perhaps a board seat, a say over future fundraising or a sale, and liquidation preferences that pay them back first if the company is sold. Those terms can matter more than the valuation. You can repay a lender and be done. An investor stays until they sell or the company does.

The options in between

Convertible notes and SAFEs are early-stage instruments that start as something like debt or a promise and convert into equity at a later funding round, which postpones the argument about valuation.

Revenue-based financing is repaid as a fixed share of monthly revenue until a set total is reached, so payments shrink in slow months. In an acquisition, seller financing lets the previous owner lend part of the purchase price, which is debt from someone with a strong interest in the business doing well.

Four questions that usually decide it

Can the business's cash flow cover a loan payment starting next month, including in a bad month? If not, debt is dangerous no matter how cheap it looks.

What happens to you personally if it fails? If the answer is a guaranteed loan taking your house, weigh that honestly against giving up a share.

How large could this plausibly become? The bigger the realistic upside, the more expensive equity gets, and the more sense it makes to borrow if the cash flow allows.

Do you want a partner? Good investors bring advice, connections and credibility, and they come with opinions you'll have to live with for years.

Key takeaways

• Debt keeps ownership but requires payments from day one; equity needs no repayment but costs a share of every future dollar.
• Equity is expensive if the business succeeds and cheap if it fails. Debt is the reverse.
• Steady, asset-backed businesses suit debt; businesses that will burn cash chasing a large outcome suit equity.
• Read the terms as closely as the headline: personal guarantees on debt and preferences or control rights on equity often matter more than the rate or the valuation.

Frequently asked questions

Is debt or equity cheaper?

It depends on the outcome. For a business that grows a lot, debt is far cheaper, because interest is capped while an investor's share grows with the company. For a business that fails, equity is cheaper, because investors share the loss while debt still has to be repaid.

Can I combine debt and equity?

Yes, and many businesses do. A company might raise some equity to prove its model and then add debt once its cash flow is steady enough to support payments, which limits how much ownership it has to sell.

Do I need a business plan to raise money?

Lenders and investors will want to understand how the money will be used and how it comes back, whether that's through cash flow to repay a loan or growth that makes shares worth more. The format varies; the numbers behind it are what they'll test.
