Why did I get charged extra interest after paying off my car loan early?
Lenders often require a multi-day payoff quote to process transactions, but they may still collect interest for the entire buffer period even if the funds are withdrawn immediately. This discrepancy leaves borrowers confused about unexpected extra charges that do not match their daily interest calculations.

“At 5% interest (and if it's tax deductible maybe effectively lower), I wouldn't bother paying more than the minimum and would prefer to invest extra cash.”source ↗
“Upon signing paper work I found out the bank raises the interest rate to 7.79% because of the loan becoming smaller.”source ↗
“My total ATF at this point is $20,000. I guess my question is should I just pay this off right away?”source ↗
“All that being said, we ended up paying about $100 more in “interest” because they used such a long payoff timeframe. Is that normal?”source ↗
“According to the finance website, we only had interest of 38.14 charged, which makes sense because my math says is about $10/day and we had the loan 4 days. But why did they withdraw an extra 95.35?”source ↗
“I understand that, and I assumed it would take the 10 days but they literally pulled the money out same day. It’s gone from my account.”source ↗
“But why? Why is that the correct amount? Their website literally says principal, interest, fees, etc and it’s $95 different from the amount we had to pay. I don’t understand how that’s the correct amount to pay on day 4.”source ↗
“im currently financing a car w/ JUST under 3k left to pay and have been considering just paying it all off, however ive been holding back because i want to go about it the smartest way possible.”source ↗
“my two main concerns are a) unexpected fees or payments (including interest) after paying the entire principal amount and b) the impact it’ll have on my credit score”source ↗
“I believe I can put an extra 200 a month twords it. My question is, is it better for my credit if I manually make the extra payments every month or wait till I have enough to payoff the remaining balance in a lump sum?”source ↗
“What are some options for aggressively paying off this loan?”source ↗
“If I decided to pay off the car I will still have a few hundred over 34k for emergency/investing”source ↗
