On your dealer quote, or from your state, provincial or national tax authority. This tool deliberately does not preset official vehicle rates for the US or Canada, because vehicle tax rules differ by jurisdiction and transaction. The United Kingdom and Switzerland prefill their official standard VAT rates (20% and 8.1%), where advertised new-car prices normally already include VAT. That is a standard-rate estimate - used-car margin-scheme, zero-rated and tax-exclusive sales differ, so match the setting to your quote.
It depends on your jurisdiction - some give a trade-in tax credit, others tax the full price. Set "Tax calculated on" to match your quote: full price, or price minus trade-in.
Vehicle price + dealer fees, minus your down payment and trade-in value - plus sales tax when you tell it tax is added on top. When tax is already included in the price, it is not added again.
It lowers the monthly payment but raises total interest, and the car can lose value faster than the loan falls. The year chart shows how much interest long terms add.
