Financing cost (Ratenkredit / Null-Prozent-Finanzierung / Leasing)
Financing cost is the gap between paying cash today and the sum of every installment paid over time — the price of spreading a purchase into future payments. A Ratenkredit (installment loan), a Null-Prozent-Finanzierung (zero-percent financing offer, often marketed as "0%-Finanzierung"), and Leasing (a lease contract) each package that cost differently, and a headline rate of 0% rarely means the cost has disappeared.
Why it matters
Retailers in Germany routinely offer Ratenkredit and "0%-Finanzierung" at checkout for furniture, electronics, and appliances, and car dealers routinely offer Leasing instead of a sale price. Recognizing financing cost, not just the stated interest rate, is what separates a genuinely cheap way to spread a payment from an offer that recovers its cost somewhere else. Building on the interest rate concept, financing cost asks a further question: across every channel a seller uses to charge for time — installments, fees, sticker-price differences — what does not paying cash today actually cost?
Worked examples
1. Ratenkredit with a stated rate — the cost is visible. A buyer finances a €1,200 laptop over 12 monthly installments at an illustrative 9% effective annual rate. Total repaid over the year: roughly €1,259 (illustrative). The financing cost — the amount paid beyond the cash price — is about €59, and it is disclosed up front as a rate the buyer can compare against other loans.
2. Comparing financing paths for the same purchase. A sofa costs €950 in cash. The same store also offers it on a 24-month Ratenkredit at an illustrative 9% effective annual rate, or on a 24-month Null-Prozent-Finanzierung with a €1,000 sticker price instead of €950. The three paths land on different totals for the identical sofa:
| Payment method | Total paid over 24 months | Financing cost vs. cash | Where the cost sits |
|---|---|---|---|
| Cash | €950 | €0 | — |
| Ratenkredit, 9% stated rate | ~€1,042 (illustrative) | ~€92 (illustrative) | Explicit rate |
| Null-Prozent-Finanzierung | €1,000 sticker price | ~€50 (illustrative) | Sticker price, not the rate |
| Leasing | periodic payments, no purchase | not directly comparable — no ownership at term end | Usage fee bundled with financing |
The stated-rate Ratenkredit is not automatically the honest, cheaper option just because its cost is visible: here it costs more than the 0%-financed sofa's hidden markup. Comparing the total euros paid, not just which product states a rate, is what actually settles which path is cheaper. Leasing sits apart from this comparison: its payments buy the use of an asset for a period, not the asset itself, so a lease's total payments have to be weighed against who owns the asset — and what it's worth — once the term ends, not just against a cash purchase price.
Don't confuse with
Financing cost on consumer credit — a Ratenkredit, a Null-Prozent-Finanzierung, a Leasing contract, a car loan, an overdraft — is priced by market credit risk: a lender or retailer sets the rate, or the price, to cover funding costs, expected defaults, and a margin, and a headline "0%" simply moves that margin into the purchase price instead of the rate. Subsidized education financing (BAföG-type) is not priced that way: the rate and any repayment cap are set by legislation, not by a lender's assessment of the individual borrower, and it can include income-contingent relief that ordinary consumer credit never offers.
Check yourself
A furniture store sells a sofa for €950 if paid in cash, or for €1,000 under a 24-month "0%-Finanzierung" (zero-percent financing) offer with no separately stated interest. What is the financing cost, in euros, of choosing the 0% offer instead of paying cash?
A buyer finances a €1,200 laptop with a Ratenkredit (installment loan) over 12 monthly installments at an effective annual rate of 9%, amortized as a standard declining-balance loan. Total repaid over the year comes to approximately €1,259. What is the financing cost, in euros (total repaid minus the €1,200 cash price)?
A retailer advertises "Null-Prozent-Finanzierung" (0% financing) on a €2,000 sofa, payable over 24 months. What does the 0% rate actually guarantee?
Which of the following correctly distinguish ordinary consumer credit (a Ratenkredit, a 0%-Finanzierung, a Leasing contract) from subsidized education financing (a BAföG-type program)? Select all that apply.
