Why capital structure matters to a first-time founder
Capital structure determines who carries risk, who receives returns and which payments the business must make regardless of sales. More debt can preserve founder ownership but adds interest, repayment dates and lender restrictions. More equity avoids scheduled repayment but dilutes ownership and may grant investors voting or consent rights.
Examples of capital structure
A company needs $500,000. It raises $300,000 by issuing shares and borrows $200,000 for four years at 9% interest. Its funding is therefore 60% equity and 40% debt by the amounts raised. The founder also reviews repayment timing, security, investor preferences and whether cash flow can cover interest during a weak quarter.
Common misunderstanding
Capital structure is not the cap table. A cap table shows who owns shares and related securities; capital structure also includes borrowings and sometimes hybrid instruments such as convertible debt. Nor does a low debt percentage automatically mean low risk, because investor rights, maturity dates and unstable cash flow also matter.
When to use it
Use it before a funding round, loan, acquisition or major investment to see how a new instrument changes control and financial pressure. Model both the percentage mix and the actual terms. Very early founders without external funding can keep the analysis simple, but should revisit it before signing any financing agreement.
