The trade-off theory of capital structure is the idea that a company chooses how much debt finance and how much equity finance to use by balancing the costs and benefits. The classical version of the hypothesis goes back to Kraus and Litzenberger who considered a balance between the dead-weight costs of bankruptcy and the tax saving benefits of debt. Often
agency costs are also included in the balance. This theory is often set up as a competitor theory to the
pecking order theory of capital structure. A review of the trade-off theory and its supporting evidence is provided by Ai, Frank, and Sanati.
An important purpose of the theory is to explain the fact that corporations usually are financed partly with
debt
Debt is an obligation that requires one party, the debtor, to pay money or other agreed-upon value to another party, the creditor. Debt is a deferred payment, or series of payments, which differentiates it from an immediate purchase. The ...

Evidence
The empirical relevance of the trade-off theory has often been questioned.
Miller
A miller is a person who operates a mill, a machine to grind a grain (for example corn or wheat) to make flour. Milling is among the oldest of human occupations. "Miller", "Milne" and other variants are common surnames, as are their equivalent ...
for example compared this balancing as akin to the balance between horse and rabbit content in a stew of one horse and one rabbit.
Taxes are large and they are sure, while bankruptcy is rare and, according to Miller, it has low dead-weight costs. Accordingly, he suggested that if the trade-off theory were true, then firms ought to have much higher debt levels than we observe in reality.
Myers
Myers as a surname has several possible origins, e.g. Old French ("physician"), Old English ("mayor"), and Old Norse ("marsh").

that makes up for most of the variation in
capital structure.
Despite such criticisms, the trade-off theory remains the dominant theory of corporate capital structure as taught in the main corporate finance textbooks. Dynamic versions of the model generally seem to offer enough flexibility in matching the data so, contrary to Miller's
verbal argument, dynamic trade-off models are very hard to reject empirically.
