When you take out a car loan and you have room in your budget to pay more than the minimum each month, you’re in a strong position to save money on interest and get out of debt faster. The key is understanding how extra payments are applied and how to make sure those payments actually reduce your principal balance, not just prepay future interest.
You borrowed about 26,000, and you can comfortably send more than the required monthly payment. That’s great. The part you need to clarify is *how* to make those extra payments: should they go only to principal, or is it okay if the payment is processed as “principal and interest”?
How car loan payments usually work
Every regular payment on an installment loan is split into two parts:
– Interest – the cost of borrowing money
– Principal – the actual amount you owe on the car
At the beginning of the loan term, a larger portion of each payment goes toward interest, and a smaller part goes to principal. Over time, as your balance drops, the interest portion shrinks and the principal portion grows.
When you “overpay” your monthly amount, that extra money *can* go directly to principal – but only if the lender applies it that way. If they don’t, they may treat it as an early payment toward future installments, which doesn’t reduce your interest costs as effectively.
Do you “only pay principal”?
You still must make at least the required payment, which always includes both principal and interest. You cannot simply skip interest; the lender charges it according to your balance and interest rate.
However, any amount you pay beyond your required monthly payment should be directed toward principal only, if your lender allows that. This is what accelerates payoff and cuts down total interest.
So in practice, the strategy is:
1. Pay the full minimum due (principal + interest).
2. Add an extra amount and make sure it is designated as a principal-only payment.
What likely happened with your first overpayment
You mention you accidentally sent an extra amount under the “principal and interest” option for your first payment. Lenders often handle that in one of two ways:
– Apply the regular part of the payment as scheduled (interest + principal),
and then
– Either:
– Apply the extra directly to principal, or
– Treat the extra as a partial prepayment of future scheduled payments (pushing your next due date out).
Which one your lender chose depends on their policy and how the payment was coded in the system. That’s why it’s important to check your loan account details: you want to see whether your *principal balance* dropped more than expected.
How to direct extra payments toward principal
Regardless of the bank, the general process is:
1. Look at your statement or app
Find your current principal balance, your interest rate, and your regular payment amount.
2. Find an option that says something like:
– “Additional principal”
– “Principal-only payment”
– “Extra payment to principal”
3. If there is no clear principal-only field
Many lenders still allow principal-only payments, but you may have to:
– Make a separate payment and select it as “extra payment”
– Or use a memo / note field to write “Apply to principal only”
4. Confirm how the lender applies extra payments
Check your transaction history and principal balance after a few days. The principal should drop by your extra amount (minus any interest owed through the date of the payment).
Specifics for using the Wells Fargo app
Interfaces change over time, but the general pattern with car loans at bigger banks is similar:
– When you make a standard payment in the app, it typically shows an option like:
– “Make a payment” or “Pay now”
– That path is usually designed for your regular monthly payment, and it may not clearly separate principal and interest – it just applies the required payment as scheduled.
To send an extra principal-only payment, look for things like:
– A separate “Additional payment” or “Extra payment” section after you enter the regular amount.
– A second amount field labeled something like “Additional principal.”
– A radio button or dropdown that allows you to choose how to apply any amount over the minimum.
If you truly do not see any label or field referring to “principal,” the safest moves are:
1. Call customer service
Ask specifically:
– How do I make an extra payment that goes only to principal?
– If I pay more than the required payment in the app, will that extra amount automatically reduce principal, or will it just advance my next due date?
– Is there a separate process (phone payment, mail, or a different online function) for principal-only payments?
2. Ask them to annotate your account
Some lenders can add a note to your account instructing that any amount in excess of the scheduled payment should always be applied to principal.
3. Verify after the fact
After your extra payment posts, check:
– Prior principal balance
– New principal balance
The difference should roughly match your extra payment (minus any accrued interest since the last payment).
Why it matters to push money into principal
Directing extra cash to principal has two main benefits:
1. Lower interest over the life of the loan
Interest is typically calculated on your remaining balance. The faster that balance falls, the less interest you accrue month by month.
2. Shorter loan term
You can cut months or even years off the loan just by consistently paying extra to principal.
On a 26,000 loan at a typical car loan rate, even an extra couple hundred per month to principal can save you a substantial sum in interest and get you debt-free far earlier than scheduled.
How to build a simple payoff strategy
To make the most of your strong financial position:
1. Decide on a fixed extra amount
For example, if your minimum is 500, you might choose to pay 700 or 800 every month.
2. Treat that as your “new normal” payment
Always cover the minimum, then send the extra amount clearly labeled (or verified) as principal-only.
3. Pay as early in the month as convenient
Paying earlier in your billing cycle can slightly reduce the interest that accrues; this effect is modest but consistent.
4. Avoid extending the term
Never agree to any offer to “lower your monthly payment” by lengthening the loan term. That typically increases total interest.
What to do about the first overpayment you already made
Since you “overpaid” under the “principal and interest” option:
1. Check your next due date
If the lender treated the extra as future payments, your next due date may have moved further out.
2. Compare the principal balance
Look at the original amortization schedule or an online loan calculator to estimate what your principal should have been after one normal payment. If your actual balance is lower than that by roughly the amount of your extra payment, then the extra likely went to principal.
3. If it didn’t go to principal
Contact the lender and ask if they can reapply the extra payment from “future installments” directly to current principal. Some will do this if you call soon after the payment.
Protecting yourself against mistakes
To avoid confusion going forward:
– Document your intentions
If allowed, include a note such as “apply overage to principal only” with online or mailed payments.
– Monitor your account online each month
Confirm how each payment is split between interest and principal.
– Keep a simple spreadsheet
Track your expected principal balance vs. the reported balance. If the gap grows, something about how payments are being applied may be off.
When it might make sense *not* to pay extra
Even though paying extra to principal is usually wise, consider the bigger picture:
– If you have high-interest credit card debt, it’s often better to pay that down first.
– If you don’t yet have a basic emergency fund, keeping some cash on hand may be more valuable than accelerating your car payoff.
– If your car loan rate is very low, the urgency is lower, though there are still benefits to being debt-free.
Still, being able to pay extra on a 26k auto loan is usually a big financial advantage, as long as the lender applies your money the way you intend.
—
In summary: you can’t avoid paying interest altogether, but you absolutely can – and should – direct any extra money to principal so you pay off the 26k faster and cut your total interest costs. With Wells Fargo (or any lender), confirm within the app or by phone how extra payments are handled, then regularly check that your principal balance is dropping in line with your extra contributions.
