You finance the price minus the down payment. If you set a residual value the payment is lower, but you owe that amount at the end. The TAEG (APR) bundles the interest and the upfront fee and measures the real cost of the credit. Leave the down payment, residual and fees at zero if they do not apply.

Educational estimate, not financial advice. It computes the capital-and-interest payment (French system) on the amount financed (price − down payment) at the TAN you choose, amortising down to the residual value, and the TAEG with the upfront fee you enter. It excludes monthly commissions, insurance and stamp duty, which can raise the bank's real TAEG.
