Paying extra on debt: questions to settle before you send the money

Putting extra money toward a debt is a choice with tradeoffs. This guide does not tell you which debt to pay first, or whether to pay extra at all. It lists the questions worth checking for credit cards, student loans and mortgages, and the official source for each answer. It does not cover loan forgiveness, income-driven repayment plans, refinancing, other loan types or whether to pay debt instead of investing.

Key takeaways

• Extra payments are not always applied the way you expect. For student loans, the CFPB says payments generally go to fees, then interest, then principal. It says you can instruct your servicer to apply an extra payment to principal, and that a servicer sometimes credits it toward a future payment instead (called "paid ahead status").
• Some mortgages have a prepayment penalty. The CFPB says it usually applies to paying off the whole balance within a set number of years, but check with your lender.
• On a credit card, the CFPB says that without a grace period, the sooner you pay down your balance, the less interest you pay.
• Extra payments reduce the cash you keep available for other needs. The CFPB says having a reserve can help you avoid borrowing for a shock, which can cost more because of interest and fees.

Two common ways people order their debts

In a 2019 article, the CFPB describes two basic approaches:

• Highest interest rate first. Put extra money toward the debt with the highest rate while paying minimums on the others. The CFPB says this eliminates your costliest debts first and can save money in the long run.
• Smallest balance first (the "snowball"). Put extra money toward the smallest debt while paying minimums on the rest, then roll the freed-up payment to the next smallest. The CFPB says you see progress quickly, but you may pay more in the long run because you are not targeting the larger or costlier debts.

The CFPB describes both and says to choose the one that fits your situation. This guide does not pick one. The article is dated July 16, 2019 and sits in the CFPB's archive. The CFPB's Debt action plan (November 2018 PDF) says one strategy is not better than the other and that each has pluses and minuses.

Questions to check for each type of debt

Debt	Question	What the source says
Credit card	How is interest calculated, and do I have a grace period?	The CFPB says many issuers calculate interest daily from your average daily balance. With a grace period you can avoid interest on purchases by paying the full balance by the due date. Without one, the sooner you pay some or all of your balance, the less interest you pay. A card can carry different rates for different transactions.
Student loan	How will my servicer apply an extra payment?	The CFPB says you are generally entitled to make extra payments without penalty, and that payments generally go first to fees, then interest, then principal. If you pay more than the minimum, you can instruct the servicer to apply the excess to principal. It says servicers sometimes credit the extra against a future payment instead ("paid ahead status," most common with federal loans) and that you can request they not do so. Its example shows a later statement with no payment due. Keep records of each transaction and conversation.
Mortgage	Do I have a prepayment penalty, and does extra principal count?	The CFPB says a prepayment penalty is a fee some lenders charge for paying off all or part of a mortgage early, and not all mortgages have one. It says it typically applies if you pay off the whole balance within a set number of years, usually three or five, and that it does not normally apply to small extra principal payments, but to double check with the lender.
Mortgage	What does extra principal do?	The CFPB says the part of a payment going to principal reduces what you owe and builds equity, while the part going to interest does not. Early in a mortgage most of each payment goes to interest.

What extra payments leave out

Extra payments reduce the cash you keep available for other needs. Before you send one, consider:

• Do you have a cash reserve for unplanned bills? The CFPB says a reserve can help you avoid relying on credit or loans, and that a one-time emergency expense put on a card or loan can grow because of interest and fees. That is a question for your own situation.
• Could you need this money soon? Ask what access, if any, remains to the money after you pay it.
• What will your monthly bill be afterward? Ask the lender whether extra payments change your required payment or only the balance.

Steps that apply to any debt

1. List each debt with its balance, interest rate, minimum payment and due date.
2. Check the terms for how extra payments are applied and any penalty.
3. Decide the order you will use, if any, with the tradeoffs in mind.
4. Ask how the extra payment will be applied, and keep records of the payment and any reply.

Bottom line

Before you send extra money, find out how the payment will be applied, whether the loan has a prepayment term, how interest accrues on the debt, and what it leaves you with for other needs. The CFPB describes two ways to order debts and says neither is better. This guide does not choose one for you.

Documents to gather

• The latest statement for each debt.
• Your mortgage note or closing documents, for any prepayment term.
• Your student loan servicer's account page.
• Your credit card terms, for the grace period and rates.

Common questions

Which debt should I pay off first?

The CFPB describes two methods, highest interest rate first and smallest balance first, with the tradeoffs above. This guide does not choose between them.

Will an extra payment lower my next bill?

Not necessarily. For student loans, the CFPB says payments generally go to fees, then interest, then principal, and that a servicer sometimes credits an extra payment toward a future payment instead ("paid ahead status"). You can instruct the servicer to apply the excess to principal.

Can a lender charge me for paying extra on a mortgage?

The CFPB says some mortgages have a prepayment penalty, usually tied to paying off the whole balance within a set number of years, and it does not normally apply to small extra principal payments. Check your note and ask your lender.

What should I send through the inquiry form?

Describe the question you want to ask. Do not submit loan statements, account numbers or other confidential financial documents.
