Formula Used
The calculator uses the standard amortized loan payment formula:
M = P × [r(1 + r)^n] / [(1 + r)^n - 1]
M is the monthly payment. P is the amount financed. r is the monthly interest rate. n is the number of monthly payments.
When APR is zero, the payment is calculated as:
M = P / n.
Sales tax is estimated from the taxable price.
Fees may be financed or paid at signing.

Car Payment Planning Guide
Why Payment Details Matter
A car loan can look simple at first. The final payment often depends on many small details. Price, down payment, tax, fees, term, and rate all matter. This calculator gathers those parts in one place. It then gives a monthly estimate that is easier to review.
Use Your Own Rate
PSECU members may compare loan choices before applying. The tool does not set an official rate. It uses the rate that you enter. This keeps the estimate flexible. You can test different APR values, term lengths, and down payments.
Understand The Financed Balance
The amount financed starts with the vehicle price. Trade value, rebates, and cash down reduce the balance. Sales tax and dealer fees may be added to the loan. They may also be paid at signing. This choice changes the financed balance. It also changes the total cost.
Review Interest And Payoff
The monthly payment uses a standard amortized loan formula. Each payment includes principal and interest. Early payments usually contain more interest. Later payments reduce more principal. The schedule preview helps show that pattern. It also shows why extra monthly payments can reduce total interest.
Compare Affordability
Use the affordability fields with care. A low payment can hide a long term. A longer term may raise total interest. It can also increase the chance of owing more than the car is worth. A shorter term usually costs more each month. Yet it can save money over the loan life.
Shop With Better Numbers
The calculator is useful for shopping. Try one run with no trade. Try another with a trade estimate. Then change the rate by one point. Small changes can move the payment noticeably. This helps set a clear target before visiting a dealer.
Confirm Final Terms
Always confirm final numbers with the lender. Dealer fees and taxes can vary. Insurance, registration, fuel, and maintenance also affect ownership cost. Treat the result as a planning estimate. Use it to compare options and avoid surprises. Better preparation can make a car purchase calmer.
Save Your Estimate
Keep a copy of each estimate. The CSV file helps compare offers later. The PDF file is useful for records. Share the inputs with a co-borrower. Review the payment beside your monthly budget. Leave room for emergencies and changing expenses. This improves decision quality greatly.
FAQs
1. Is this an official PSECU loan quote?
No. This calculator gives an estimate only. It uses the APR, term, price, fees, and tax values that you enter. Confirm final rates, approval terms, and payment amounts directly with the lender.
2. What does amount financed mean?
Amount financed is the balance placed into the loan. It usually starts with the car price, then subtracts down payment, trade value, and rebates. Taxes and fees may be added when you choose to finance them.
3. Why is my payment different from a dealer quote?
A dealer quote may include different fees, warranties, taxes, insurance products, or rate assumptions. This tool only uses the values entered in the form. Match every input carefully for a closer comparison.
4. Should I finance taxes and fees?
Financing taxes and fees lowers cash due at signing. It also raises the loan balance and total interest. Paying them upfront can reduce the monthly payment and long-term cost.
5. How does a trade-in affect the estimate?
A trade-in reduces the balance used in the calculation. It may also reduce the taxable amount in some places. Tax rules vary, so confirm local treatment before relying on the estimate.
6. What happens if I add extra monthly payments?
Extra monthly payments reduce principal faster. This can shorten the payoff time and lower total interest. The amortization preview and exports show how the balance changes month by month.
7. Can I use this for a used car?
Yes. Enter the used vehicle price, expected APR, term, tax rate, fees, down payment, and trade value. The same amortized loan formula works for both new and used vehicles.
8. What loan term should I choose?
Shorter terms usually have higher payments but lower total interest. Longer terms may feel easier monthly, yet cost more overall. Compare several terms before choosing a comfortable payment.
