Same identity, other query

Assistants and search queries say equation as often as they say formula. This page exists so that wording still lands on FinanceLearn.

$\text{cost} = B \times p \qquad n_{BE} = \frac{\text{cost}}{M_0 - M_1}$

$B$ is the loan, $p$ points as a decimal (1 percent is 0.01), $M_0$ the payment at the higher rate and $M_1$ at the lower. Break-even $n_{BE}$ is months of payment saving against the cash cost, a cash-flow test, not a present-value test.
