Advertiser disclosure: RefiMeNow is a comparison marketplace, not a lender. We receive compensation from network lenders, which may affect placement. How we review
PenFed posts the lowest published refinance rates in our network, with used-auto APRs advertised from 4.79%, no origination or document fees, and the ability to refinance up to 125% of your current balance, which covers taxes, payoff gaps, and a little negative equity. Despite the Pentagon name, anyone can join with a $5 savings account.
The catch is a fairly disciplined box: mileage tops out around 125,000, there is no pricing below the fair band, and PenFed sticks to rate-and-term refinancing, so cash-out and lease buyouts route elsewhere in the network. Inside that box, it is the rate leader.

Where PenFed Credit Union prices against the network
Auto refinance rates step down in credit tiers, so the fastest way to judge a lender is to find your band and compare its estimate against the network as a whole. An illustrative payment makes the percentages concrete.

See my lowest rateWhat it does well
- Published used refinance APRs from 4.79%
- No origination or document fees
- Refinance up to 125% of your current balance
- Loans up to $150,000, terms to 84 months
Where it gives ground
- Mileage capped around 125,000
- No cash-out or lease buyout programs
- No pricing for rebuilding credit
PenFed Credit Union is a fit if
- Strong-credit borrowers chasing the lowest published rate
- Drivers with a payoff slightly above the car's value (the 125% cushion)
- Fee-averse shoppers
Look elsewhere if
- High-mileage vehicles past about 125,000 miles
- Anyone who needs cash-out or a lease buyout
Why the 125% cushion matters
Most lenders cap a refinance at your car's value. PenFed publishes the ability to refinance up to 125% of your balance, which quietly solves the most common refinance blocker: owing slightly more than the car is worth after taxes and fees rolled into the original dealer loan.
Pair that with no origination or document fees and the published 4.79% used-auto floor, and PenFed is the network's purest rate play for a mainstream car with reasonable miles.
The Pentagon name, without the service requirement
PenFed began as a military credit union, but membership has been open to everyone for years: a $5 savings account is the whole barrier. The military heritage shows up as scale, over-conservative it is not; PenFed is one of the country's largest credit unions and prices like it.
The discipline shows in the box: about 610 credit and 125,000 miles are real lines, and the program list is intentionally short. When your profile fits, few beat it on price.
