TransparentShort answer. "No down payment" (sem entrada) isn't free money. Not putting money down means you finance a bigger amount, and a bigger amount pays more interest — on the same car, over the same term, it always costs more in total. On an €8,000 car over 5 years, putting €2,000 down instead of zero saves you about €550 in interest (and more, if the bank charges a higher rate for going sem entrada). What no-down-payment solves is today: you don't need the cash up front. What it costs is the total. Below is the comparison worked to the euro on the same car, and when going sem entrada still makes sense.
This is general information, not personalised financial advice. TransparentCars does not lend and is not a credit intermediary (não é intermediário de crédito) — financing is handled by partners authorised by the Bank of Portugal, who decide approval and rates. The figures below are illustrative, to show the order of magnitude.
How much more it costs to go with no down payment
Same car, same term, same rate. The only difference is how much you finance. An €8,000 car, 60 months, illustrative APR (TAEG) of 10%:
| A — €2,000 down | B — no down payment | |
|---|---|---|
| Amount financed | €6,000 | €8,000 |
| Monthly payment | €127 | €170 |
| Total paid to bank (60×) | €7,649 | €10,199 |
| Down payment (paid from pocket) | €2,000 | €0 |
| Total cost of the car | €9,649 | €10,199 |
| Difference | — | +€550 |
The trick in the maths: the payment rises €42.50 a month (from €127 to €170). Over 60 months that's €2,550 — which is exactly the €2,000 you didn't put down + €550 of interest on top. In other words, going sem entrada is borrowing €2,000 more from the bank… and paying interest on it for five years.
And that's the best case, with the same rate in both columns. Often it isn't: by financing 100% of the car the bank takes more risk and may apply a higher rate. If column B rises to 12% APR, the payment becomes €178 and the total goes to €10,677 — the gap versus putting money down jumps to about €1,029.
Why no down payment always costs more
No mystery, no hidden fine print. Interest is charged on the outstanding balance. The higher the amount you finance, the more interest runs — every month, for the whole term. A down payment isn't a "fee" or a loss: it's money you hand straight to the value of the car, and that you never pay interest on. Every euro of down payment is a euro that won't earn the bank interest.
Beyond the higher total, no down payment usually brings two practical consequences:
- Stricter approval. Financing 100% weighs more on your effort rate and on the bank's risk. A profile that would pass with €2,000 down can sit at the limit without it.
- A longer term to "hide" the payment. To keep the monthly figure from scaring you, it's tempting to stretch to 84 or 96 months — and then you pay even more interest. A short term with a down payment almost always beats a long term with none.
The risk of owing more than the car is worth
A car loses value the day it leaves the lot. If you financed 100%, in the first months your debt to the bank is bigger than the car's market value — that's being "underwater" (upside down).
Concrete example on the €8,000 car: after a few months it might be worth ~€7,000 if you tried to sell it. With €2,000 down, you owe €6,000 and still have a cushion. With no down payment, you owe close to €8,000 on a car worth €7,000 — if you need to sell, or if it's written off in a crash, you cover the difference out of pocket. The down payment is the buffer that keeps you out of that hole early on.
When going with no down payment still makes sense
No down payment costs more overall — but there are honest situations where the choice is defensible, as long as you make it with eyes open:
- Keeping your emergency cushion. If the down payment leaves you with no savings at all, the extra €550 can buy peace of mind. Being stuck with no car and no money for a breakdown is worse.
- The money works harder elsewhere. If you carry credit-card debt at 18%, clearing that first beats putting money down to save 10%.
- You need the car now and the down payment is only months away. Sometimes the cost of having no car (for work) outweighs the €550.
What is not a good reason: "no down payment because it's easier". Easier today, dearer for five years. If you have the money and don't need it elsewhere, the down payment is almost always the better call.
How to decide the right down payment
There's no magic number — there's the number that balances your wallet today against the total you're willing to pay. A good rule of thumb: put down the most you can without emptying your emergency fund (ideally 3 to 6 months of expenses left untouched). Then check the numbers:
- Open the car-loan calculator and set the down payment to 0. Note the payment and the total.
- Simulate again with a down payment (€1,000, €2,000, €3,000) and compare the payment and total paid.
- See how much you save per €1,000 of down payment — and decide where your money works best.
Compare with and without a down payment before you sign. Run both simulations in TransparentCars' car-loan calculator — down payment at 0 vs. a value — see to the euro what the convenience of skipping the down payment costs you, and take those numbers to an authorised credit partner.
Illustrative simulations; the APR, the payment and approval depend on the analysis of the credit partner authorised by the Bank of Portugal.
