Long-term car hire in Porto is much cheaper per day than short rentals.
Monthly rates are far lower per day than weekly or daily hire. Expect roughly the following in 2026:
Long-Term (Monthly) Rates in Porto by Season
28–30 day rental, booked in advance, prices in EUR
| Season | Economy (monthly) | Compact (monthly) | Automatic (monthly) |
|---|---|---|---|
| Low (Nov–Feb) | €450–600 | €540–720 | €720–980 |
| Shoulder (Mar–May, Oct) | €560–720 | €660–880 | €860–1,150 |

Monthly rental suits remote workers, long stays and snowbirds in Porto.
Long-term rental usually means 28 days or more on a single agreement, which unlocks much lower daily rates than short hire. Some companies offer rolling monthly contracts (Guerin in renewable 28-day blocks, Europcar from 28 days up to 24 months); others sell car subscriptions such as SIXT+ or Drivalia CarCloud, with a 30-day minimum. The deposit, mileage allowance and maintenance terms matter more than on a short rental, so read them carefully.
A well-rated home-grown brand with a monthly rental in renewable 28-day blocks (up to 12 months) that bundles maintenance, insurance and 24-hour assistance, with 2,000 km included as standard. It has a Porto Airport station.
A dependable major whose Portuguese long-term product runs from 28 days to 24 months with no early-termination penalty – good for maintenance support over a long rental.
Its SIXT+ subscription is available in Porto (30-day minimum, about €700–750 a month plus a €200 sign-up fee), with 3,500 km, insurance, maintenance and Via Verde tolls included – pricier, but newer cars and flexible terms. Drivalia CarCloud is a cheaper subscription alternative with stores at Porto Airport and Campanhã.
Aggressive upsells, fuel and damage disputes – especially risky over a long rental where issues compound.
The cheapest long-term listings can carry tight mileage caps and excess disputes. Read the fine print or stick with a trusted brand.
A long-term car opens up the Douro Valley and northern Portugal from your Porto base.
On a one-month rental, the counter's Super CDW at €15–24/day adds up to €450–720 – sometimes as much as the car itself.
An annual or multi-trip standalone excess policy (often €40–90 for the year) covers the excess, tyres, glass and underbody for every rental day – far cheaper than daily counter cover for a long stay.
