The essentials
Short-term rental in Portugal can generate, on average, around 40% more net income than traditional long-term letting for well-positioned properties. The difference comes down to four variables: average nightly rate, occupancy, operating costs and tax burden. Under the simplified tax regime, personal income tax (IRS) applies to just 15% of gross revenue from short-term rental — known in Portugal as Alojamento Local (AL) — making the tax impact more favourable than many property owners expect. That said, returns are not universal: properties in containment zones in Porto or Lisbon, with low seasonal occupancy, or under-optimised management, can narrow or eliminate the advantage over traditional letting. Use the short-term rental profitability calculator to run the numbers for your specific property.
Before starting a short-term rental, the question is almost always the same: does it pay off? The answer is not straightforward. It depends on the property, the location and the management model. This article gives you a calculation framework with real market data so you can make the decision with concrete information.
What determines whether short-term rental pays off
The profitability of a short-term rental — known in Portugal as Alojamento Local (AL) — depends on four variables. Changing any one of them significantly alters the final result.
Average daily rate (ADR). This is the single largest driver of profitability. A two-bedroom apartment in central Porto may have an ADR of €120. The same apartment in Braga might achieve €70–80. The difference reflects tourist demand, local competition and listing quality.
Occupancy rate. A property with a high ADR but low occupancy can earn less than one with a lower rate but consistent bookings. In Portugal, short-term rental occupancy rates range between 55% and 80%, depending on the city, season and management quality.
Operating costs. Cleaning fees, platform commissions (Airbnb charges approximately 3%, Booking.com charges 15–18%), consumables, maintenance and liability insurance. Together, these typically represent 30–40% of gross revenue.
Tax burden. Under Portugal’s simplified tax regime, personal income tax (IRS) applies to just 15% of gross revenue from short-term rental activity, under Article 31(1)(a) of the Portuguese Income Tax Code (CIRS). Social Security contributions apply at 21.4% on 20% of revenue. Property owners with annual revenue below €15,000 are exempt from VAT under Article 53 of the Portuguese VAT Code (CIVA), as amended by Decree-Law 35/2025. To calculate your specific tax obligations, use the short-term rental tax simulator.

A real-numbers example: two-bedroom apartment in Porto
The figures below are representative market values for a well-managed two-bedroom apartment in Porto. Your specific property may differ — the calculator at the end of this article lets you personalise the calculation.
| Item | Value |
|---|---|
| Average nightly rate (ADR) | €120 |
| Occupancy rate | 70% (~255 nights/year) |
| Annual gross revenue | ~€30,600 |
| OTA commissions (15% average) | €4,590 |
| Cleaning and consumables | €3,800 |
| Maintenance, insurance and other | €2,100 |
| Total operating costs | ~€10,490 (34%) |
| Net operating revenue | ~€20,110 |
| Estimated tax burden (IRS Cat. B + Social Security) | ~€2,000–3,000 |
| Estimated net income | ~€17,000–18,000/year |
The same two-bedroom apartment in traditional long-term letting at €950/month generates €11,400 in annual gross revenue. After property tax, basic maintenance and any vacancy periods, net income typically ranges from €9,500 to €10,000 per year.
In this specific example, short-term rental generates significantly more net income than traditional letting. On average, across professionally managed properties in Portugal, the advantage over traditional letting is around 40%. To run the calculation with your own property data, use the short-term rental profitability calculator — it automatically compares all three scenarios: self-management, professional management and traditional letting.
When short-term rental may not pay off
Not all properties have the same profitability equation. There are three scenarios where short-term rental may not outperform traditional letting.
Containment zones in Porto and Lisbon. In certain parishes, opening new short-term rentals may be subject to administrative restrictions and the annual property tax (IMI) may be increased by up to 100% of the base rate. Before proceeding, check whether your property is in a containment zone in Porto or a containment zone in Lisbon.
Extreme seasonality without a complement. Properties with 90% occupancy in July and August but near zero from November to March face a different equation. The break-even occupancy — the minimum rate at which short-term rental outperforms traditional letting — is typically 45–55%. Below that threshold, traditional letting may be the better option.
Under-optimised self-management. Short-term rental requires availability for check-ins, fast guest communication and cleaning coordination. A property owner without that time, who does not hire support, tends to see listing ratings decline over time, which reduces both occupancy and nightly rates.
Short-term rental vs traditional letting: what the numbers show
The comparison between the two models goes beyond gross revenue.
| Criterion | Short-term rental | Traditional letting |
|---|---|---|
| Annual gross revenue (Porto 2BR) | ~€30,600 | ~€11,400 |
| Operating costs | High (30–40%) | Low (10–15%) |
| Estimated net income | ~€17,500 | ~€9,700 |
| Income variability | High (occupancy-dependent) | Low (fixed rent) |
| Flexibility of use | High (simple blocking) | Low (1+ year contract) |
| Management effort | High (self-management) | Low |
Short-term rental generates more revenue and more net income, but with greater variability and operational demands. For property owners who value predictability above all else, traditional letting may be more appropriate.

The impact of management model on profitability
This is the factor that most separates outcomes in practice.
With self-management, the property owner handles check-ins, communication, cleaning and maintenance. You retain 100% of net operating income but invest time directly. For a single well-occupied apartment, the typical weekly time commitment is 8–12 hours.
With professional management, the company charges a commission on revenue — typically 15–25%. In exchange, it handles the entire operation: dynamic pricing, multi-platform distribution, housekeeping, check-ins and 24/7 guest communication. In practice, properties under professional management tend to achieve higher occupancy and better-optimised nightly rates, which frequently offsets the commission charged.
A third model — guaranteed profitability — has the operator pay a fixed monthly income to the property owner, regardless of occupancy. This suits owners who want full predictability and zero operational involvement.

In containment zones in Porto and Lisbon, opening new short-term rentals may be subject to administrative restrictions and the annual property tax (IMI) may be increased by up to 100% of the base rate under Article 112(19) of the Portuguese Property Tax Code (CIMI). Checking the containment zone map for your municipality before proceeding is essential.
Self-management retains more gross income but requires permanent availability for check-ins, cleaning and guest communication. Professional management charges a commission of 15–25% but tends to achieve higher occupancy and better-optimised nightly rates, often covering the cost of the commission. The profitability calculator lets you compare both scenarios with your specific property data.
Income varies significantly with location, property type and management model. A two-bedroom apartment in Porto with an average nightly rate of 120 euros and 70% occupancy generates approximately 30,600 euros in annual gross revenue. After operating costs (34%) and estimated taxes, net income is approximately 17,000–18,000 euros per year. In less tourist-heavy cities, figures can be significantly lower.
Yes. Having a mortgage does not prevent registration as a short-term rental in Portugal. You must register the activity with the national short-term rental registry (RNAL) and comply with all tax obligations. Check your mortgage contract for any clauses restricting commercial use of the property, as some lenders include such restrictions.
