Can my loan payment increase without warning?

Fixed-rate loans should not change, but your total payment can increase due to escrow adjustments. For adjustable-rate loans and variable credit lines, payments can change with interest rates. Lenders must provide notice for most changes.

Why did my car payment go up?

Auto loans are almost always fixed-rate, so the payment should not change. If it did, check for errors, fees added to the balance, or changes to your payment date. Contact your lender to clarify.

Is it normal for mortgage payments to increase?

Yes, even with a fixed-rate mortgage. While your principal and interest stay the same, your escrow payment for property taxes and insurance can change annually, causing your total payment to increase.

What should I do if I cannot afford the increased payment?

Contact your lender immediately. Options may include payment plans, escrow cushion adjustments, forbearance, or loan modification. The worst thing is to ignore it—that leads to late fees and credit damage.
