What should I check before relying on it?

Does the trade-in value reduce the sales tax owed?
In many places, yes, but this calculator applies the sales-tax rate to the full car price rather than netting out the trade-in first — check your local tax rules if trade-in tax credits apply where you live.
How much does a larger down payment lower my monthly payment?
It reduces the amount financed directly, which lowers both the monthly payment and the total interest paid over the loan term — try adjusting the down payment to compare.
