Frequently Asked Questions: Auto & Car Loan Calculator
Answers to common questions regarding inputs, calculations, and mathematical methodology.
Does trade-in reduce auto sales tax?
In most US states and Canadian provinces, trade-in credit reduces the taxable purchase price. For instance, on a $30,000 vehicle with a $10,000 trade-in, sales tax is only levied on the remaining $20,000 difference.
What is an ideal auto loan term length?
Financial planners recommend limiting new car loans to 48 or 60 months (and used car loans to 36 or 48 months) to prevent becoming 'upside-down' (owing more than the vehicle's depreciating market value).
Can I export my car loan amortization to Excel?
Yes, click the 'Export to Excel (.xlsx)' button to download the yearly breakdown of principal, interest, and remaining balance.
