Explanation
How Car financing calculator works
The car financing calculator models vehicle financing as a classic instalment loan or as a balloon financing with a final payment. It uses the same annuity logic as the existing loan calculators and does not create a parallel interest formula.
Final-payment rateAnnuity(financing amount − present value of the final instalment)
The present value of the final payment is deducted; a final payment of 0 yields the classic annuity.
Total costsInstalments × term + final instalment
Plus the down payment and trade-in as capital contributed.
Practice
Practical examples
For illustration only – your own calculation is what counts.
Classic instalment loan without a final payment
Vehicle price EUR 30,000, down payment EUR 5,000, trade-in EUR 3,000, 5.0 % borrowing rate, 48 months, EUR 0 fees, no final payment.
Result: Financing amount EUR 22,000; monthly payment of around EUR 506.64 over 48 months.
Balloon financing with a final payment
Vehicle price EUR 30,000, down payment EUR 5,000, no trade-in, 5.0 % borrowing rate, 48 months, EUR 0 fees, final payment EUR 12,000.
Result: Financing amount EUR 25,000; a lower monthly payment and a final payment of EUR 12,000 (around 40 % of the vehicle price).
Notes
Common mistakes
Final payment forgotten in planning
Only the low monthly payment is considered.
Plan the final payment as a large closing amount.
Down payment and trade-in not deducted
The full vehicle price is financed.
Deduct the down payment and trade-in from the financing amount.
Borrowing rate confused with effective rate
The entered borrowing rate is read as the effective annual rate.
The relevant effective annual rate under the PAngV is stated in the provider's offer.
FAQ
Frequently asked questions
How does the financing amount arise?
Vehicle price plus fees minus the down payment minus the trade-in. A negative amount is limited to zero.
How is the monthly payment calculated?
Using the same annuity formula as the existing loan and property calculators. There is no different interest formula.
What is a classic instalment loan?
The financing amount is fully repaid through equal monthly payments. No final payment remains at the end.
What is a balloon or final-payment financing?
A portion remains open as a guaranteed final payment at the end of the term. The monthly payments are lower, but a large amount is due at the end.
How is the payment determined with a final payment?
The present value of the final payment is deducted from the financing amount and the rest is repaid on an annuity basis. A final payment of zero yields exactly the classic payment.
What does the final-payment ratio mean?
The calculator shows the final payment in relation to the vehicle price and the financing amount. A high ratio increases the follow-on risk.
Is the total interest binding?
No. It is based on the entered borrowing rate over the entire term. The contractual effective annual rate under the PAngV may differ.
What does the amortisation schedule show?
It presents the interest and principal shares as well as the remaining balance per month. With balloon financing the final payment remains as the closing balance.
Does the calculator use the existing loan logic?
Yes. It uses the same shared annuity and amortisation-schedule functions and only extends them by the final payment.
Is this a loan commitment?
No. The calculator checks neither creditworthiness nor the effective annual rate or contract terms. The result is model orientation.
Limits
Limitations
The borrowing rate remains constant over the entire term; interest-rate changes are not reflected.
No legally relevant effective annual rate under the PAngV is determined.
