Property investment: how do you calculate the rental return on a luxury chalet? 2025

Investing in a luxury mountain chalet can appeal to many people, whether for its prestige or its potential rental yield. Calculating the rental return on this type of property requires a methodical and precise approach. A number of factors need to be taken into account, including rents, associated costs and the tax regime. This article guides you through the various stages involved in assessing the profitability of your property investment.

The essentials for calculating rental profitability

Identifying rental income

To estimate the rental profitability of a luxury chalet, the first step is to identify the potential rental income. These rents vary according to location, size, services offered and time of year. For example, a chalet located near the ski slopes generally generates higher rents during the winter season.

It’s vital to gather precise information on the rents charged in the region and to estimate an average annual rent:

  • Winter season (high season): 12 weeks at €3,000 per week = €36,000
  • Summer season (low season): 10 weeks at €2,000 per week = €20,000

Total estimated annual rental income: €56,000

Taking into account costs and charges

Property-related costs play a significant role in calculating rental profitability. They include :

  • Fixed costs: property tax, co-ownership charges, insurance
  • Variable costs: maintenance, repairs, household services
  • Specific costs: rental management costs if you use an agency

Example of annual costs :

  • Property tax: €5,000
  • Insurance: €2,500
  • Maintenance and services: €8,000

Total estimated annual costs: €15,500

Calculate gross profitability

Gross profitability provides an initial, quick estimate of investment performance. It is calculated as follows:

Calculation formula: Gross return = (Annual rental income / Purchase price of the property) x 100

For example, for a chalet purchased for €800,000 with rental income of €56,000:

Gross return = (€56,000 / €800,000) x 100 = 7%.

Take account of tax and the tax system

The tax regime applied to your rental will have a direct impact on your profitability. Common options :

  • Micro-foncier scheme for gross income of less than €15,000/year, offering a flat-rate allowance of 30%.
  • Régime réel, which deducts actual expenses but requires more administrative formalities.

Given rental income of €56,000, the actual scheme could be more advantageous for deducting all actual costs.

  • Gross rental income: €56,000
  • Annual costs: €15,500

Actual taxable income: €40,500

Income tax: varies according to marginal tax bracket.

Estimating other deductible expenses

Under the actual scheme, a number of expenses can still be deducted:

  • Loan interest: for example, if you have a loan with annual interest of €10,000.
  • Improvement costs (not reconstruction): various works to maintain the quality of the chalet.

After these deductions :

  • Adjusted taxable income: €40,500 – €10,000 = €30,500

Other profitability indicators

Net-net return

This calculation takes into account all charges and taxes for a complete picture.

Calculation formula: Net yield = ((rent – charges – tax) / purchase price) x 100

Using our previous examples:

Net-net yield = ((€56,000 – €15,500 – €9,150) / €800,000) x 100 = 3.92%.

(where €9,150 represents simplified tax)

Cash flow

Cash flow indicates the capacity of the investment to generate a financial surplus after all expenditure.

Calculation formula: Cash flow = Rental income – Monthly repayments – Costs and charges

If your monthly loan payment is €2,500 :

Annual cash flow = €56,000 – (12 x €2,500) – €15,500 = €6,500

The leverage effect of borrowing

Using a loan to finance your investment can greatly increase your net profitability. It allows you to take advantage of historically low interest rates while maximising the tax deductions associated with interest on the loan.
