Becu Auto Loan Calculator
Estimate your BECU auto loan payment
BECU, the Boeing Employees Credit Union, is one of the largest credit unions in the country and a popular lender for new and used auto loans in the Pacific Northwest. This calculator estimates your monthly payment, total interest, and total cost for a BECU-style auto loan using the standard amortization formula. It is an independent estimator: it is not affiliated with BECU, and your actual rate and approval depend on BECU’s current rate sheet and your credit profile.
Unlike basic payment calculators, this one computes the true amount financed: vehicle price, minus down payment and trade-in, plus sales tax (on the price after trade-in) and fees. That is the number your payment is actually based on.
BECU auto loan rates for reference
BECU publishes its rate schedule regularly. As of the schedule effective August 1, 2026, advertised APR ranges were 5.74% to 18% for new autos (2024 and newer) and 6.04% to 18% for used autos (2023 to 2011). Rates change, so check BECU’s current disclosures before you apply, and enter your actual offered APR in the calculator for the most accurate estimate.
Worked example: zero down
A $30,000 vehicle with $0 down at 6% APR over 60 months. Many lenders, including BECU, allow qualified buyers to finance 100% of the price, and this calculator accepts a $0 down payment:
- Amount financed: $30,000.00
- Monthly payment: $579.98
- Total interest paid: $4,799.04
- Total of 60 payments: $34,799.04
A second example with the extras: $35,000 price, $5,000 down, $4,000 trade-in, 6.5% sales tax, $500 in fees, 5.74% APR, 60 months. Taxable amount is $31,000, tax is $2,015.00, amount financed is $28,515.00, monthly payment is $547.83, total interest is $4,355.04, and the out-the-door cost is $41,870.04.
How to use this calculator
- Vehicle price: the sticker or negotiated price before anything else.
- Down payment: cash you put down. Zero is allowed.
- Trade-in value: what your old car is worth. In most states this also reduces the taxable amount.
- Sales tax: your local rate. The calculator applies it to the price minus trade-in.
- Fees: documentation, title, and registration fees rolled into the loan.
- APR: the annual rate BECU offers you. Try both ends of the advertised range to see the difference.
- Term: 24 to 84 months. Longer terms lower the payment but raise total interest.
Why credit unions often beat dealer financing
Credit unions are not-for-profit, so they typically price auto loans below bank and dealer rates for the same credit profile. Getting pre-approved with BECU before visiting a dealership also turns you into a cash buyer at the negotiating table: the dealer has to beat your rate to earn your financing business. Compare the total interest, not just the monthly payment, when a dealer offers to stretch your term.
>Frequently asked questions
Is this calculator affiliated with BECU?
No. This is an independent estimator built with the standard auto-loan amortization formula. It is not affiliated with, endorsed by, or sponsored by BECU (Boeing Employees Credit Union). For official rates and applications, use BECU's own website.
What are BECU's current auto loan rates?
BECU publishes a rate schedule that changes over time. The schedule effective August 1, 2026 advertised 5.74% to 18% APR for new autos and 6.04% to 18% for used autos. Your actual rate depends on your credit, the loan term, and the vehicle. Always check the current schedule before applying.
Can I get a BECU auto loan with $0 down?
Qualified buyers can often finance 100% of the vehicle price, which is why this calculator accepts a $0 down payment. Putting money down still helps: it lowers your monthly payment, reduces total interest, and protects you from owing more than the car is worth.
Does trade-in reduce sales tax?
In most states, yes: sales tax is charged on the purchase price minus the trade-in value. This calculator applies your tax rate to the price after trade-in. A few states tax the full price, so check your local rules.
Is a longer term better for an auto loan?
A longer term lowers the monthly payment but increases total interest and the risk of going upside down (owing more than the car is worth). Compare total interest across terms: the cheapest payment is rarely the cheapest loan.
What credit score do I need for the best BECU rate?
BECU, like most lenders, reserves its lowest advertised rates for borrowers with excellent credit. If your offered APR is near the top of the range, improving your credit before you buy, or making a larger down payment, can meaningfully cut your total cost.
