Frequently asked questions
Which costs less overall?
Under Nestfigure’s constant-rate model, biweekly usually pays less total interest because principal falls faster. Real servicer rules may differ.
Is biweekly always better for cash flow?
Not always. You pay more over a calendar year (about one extra monthly payment). Nestfigure does not give budgeting advice.
