Rental yield in Paris: how to calculate it (and improve it)

Rental yield is the number everyone quotes and almost nobody calculates the same way. Between the figure in a listing and what actually reaches your bank account, the gap is rarely measured in tenths of a point.

In Paris, the question is even more sensitive than elsewhere: purchase prices are among the highest in France, rents are capped under rent control, and taxation weighs heavily. An owner who reasons on gross yield alone is almost always wrong — and the margin of error is enough to turn a good deal into a mediocre investment.

Here is the complete method: the three levels of calculation, the mistakes that skew the result, and the levers you can realistically act on in a market as constrained as Paris.

The three layers of rental yield

There is not one yield but three. Each answers a different question, and only the last tells you what the apartment really earns you.

1. Gross yield: the order of magnitude

This is the simplest calculation, and the one you find everywhere: (monthly rent × 12) ÷ purchase price × 100.

Take a purely illustrative example: an apartment bought for €400,000 and rented at €1,400 a month. Annual rent comes to €16,800, for a gross yield of 4.2%. This figure has one merit — it lets you compare two properties quickly — and one major flaw: it ignores absolutely everything that comes out of your pocket.

One clarification already changes the result: the “purchase price” must include notary fees, agency fees and any work carried out before the property is let. On a Paris property, these items are not trivial. Forgetting them mechanically inflates the displayed yield.

2. Net yield after expenses: the reality of operating the property

Here you subtract everything that owning the property costs each year, before tax:

• Property tax, which keeps rising in Paris.
• Non-recoverable co-ownership (condominium) charges — those that remain your responsibility and are not re-billed to the tenant.
• Non-occupant landlord insurance (PNO) and, where applicable, unpaid-rent insurance.
• Management fees if you use an agency.
• Maintenance and small recurring repairs: boiler, plumbing, refurbishment between two tenants.
• Vacancy, that is, the months without rent between two leases.

This last item is the one that optimistic calculations most often sweep under the rug. An empty apartment doesn’t just cost you the missed rent: charges and property tax keep running, and re-letting has a price of its own. We detailed the full calculation in our article on the real cost of vacancy in Paris.

3. After-tax yield: what you are left with after tax

This is the only figure that counts when making a decision. It factors in the taxation of rental income under the regime you have chosen, plus social contributions.

The gap between net yield and after-tax yield depends entirely on your situation: marginal tax bracket, tax regime, depreciation in furnished rentals. Two owners holding the same apartment at the same rent can show very different after-tax yields. That is precisely why a yield quoted by a seller has no value for you: it was not calculated with your tax situation. The choice of regime is covered in our article on the taxation of furnished rentals in Paris.

The most common calculation mistakes

1. Reasoning on the advertised rent rather than the rent collected. The former is theoretical; the latter accounts for vacant months and any unpaid rent.
2. Forgetting acquisition costs. Yield is calculated on what the property actually cost you, not on the price shown in the listing.
3. Confusing recoverable and non-recoverable charges. Only the latter weigh on your yield.
4. Ignoring the time spent. It appears on no accounting line, but managing a property yourself means real hours. A 4% yield earned by devoting two weekends a year to it is not worth the same as a 4% yield that costs you thirty hours.
5. Counting on capital gain to make up for a weak yield. That is a bet, not a calculation. It should never be used to justify an operation that runs at a loss.

Levers to improve yield in Paris

In Paris, two of the three classic variables are largely constrained. The purchase price is a done deal if you already own. And rent cannot be set freely: rent control imposes a cap depending on the area, the number of rooms, the construction period and whether the property is furnished or not. Hoping to improve your yield simply by raising the rent is therefore not a viable strategy.

That leaves more discreet levers, but entirely real ones.

Reduce vacancy

This is the biggest and most neglected source of gain. Going from two empty months a year to zero improves net yield more than most tax optimizations — with no renovation work, no risk and no additional capital.

Choose the right lease type and the right tenant profile

A furnished apartment rented to a professional clientele on assignment doesn’t follow the same economics as a conventional unfurnished rental: different rent per square meter, different turnover, different applicable framework. Our comparison furnished or unfurnished rental in Paris details the trade-offs.

Control the cost of management

Agency fees, tenant-placement fees, billed call-outs: these items add up and are rarely compared. We reviewed them in how much rental management really costs in Paris.

Treat energy performance as an investment

Energy improvement work weighs on yield in the year it is carried out, but protects the property’s ability to be rented in the medium term. A dwelling that can no longer be rented has a yield of zero. The subject is covered in energy performance certificate (DPE) and renovation work: what obligations apply to renting in Paris.

Secure yield versus theoretical yield

One point that calculation tables show poorly: two identical yields on paper are not worth the same if one is certain and the other is not. A net yield of 3.4% collected twelve months out of twelve, with no involvement on your part, is worth more than a yield of 4.1% that assumes perfect occupancy, no unpaid rent and flawless management — three assumptions that do not all come true every year.

Reasoning in terms of expected yield rather than advertised yield is the main change of method we recommend to a Paris owner.

The five-step method

1. Establish the true cost basis: price paid, notary fees, agency fees, initial renovation work.
2. Use the rent collected, not the advertised rent: apply a realistic vacancy assumption for your property and your neighborhood.
3. List all non-recoverable annual charges, maintenance and management included.
4. Apply your own taxation, with your bracket and your regime — not a generic case.
5. Compare the scenarios with one another, including the one where you no longer manage anything. The time you get back has a value.

An honestly calculated yield is often lower than the one you had hoped for. That is good news: it is from this figure, and only from it, that the decisions that follow are sound ones.
