How Much Will Borrowing Cost You?

The NCPA's 401(k) Borrowing Calculator can help you determine how much a 401(k) loan will cost in terms of lost savings and investment opportunities. The calculator will:

Make annual comparisons of your projected 401(k) balance, with and without a loan, from the year you borrow until the year you retire.
Compare your monthly income when you retire, with and without a loan, based on a 30-year fixed annuity.

Place your cursor over each box for further explanation of the variable fields.
