The gross rent refers to the total amount paid by the tenant, including charges. The net rent corresponds to what the owner actually receives after deducting non-recoverable charges, management fees, and taxes. Confusing these two amounts skews any rental profitability estimate even before signing a preliminary agreement.
Non-recoverable charges and works: what really separates gross from net
The distinction between gross rent and net rent primarily depends on the nature of the charges deducted, as some are predictable and others are not.

Recoverable charges (cold water, maintenance of common areas, household waste) are re-invoiced to the tenant. They inflate the gross rent but do not enrich the landlord. The non-recoverable charges, on the other hand, remain the responsibility of the owner: property tax, non-occupant owner insurance, property management fees, provisions for major works.
Before going further, it is useful to understand the difference between gross and net rent in detail, particularly to distinguish what falls under charge provisions and what falls under definitive charges.

The co-ownership works voted in general assembly also weigh on net yield. A façade renovation or roof replacement can represent several years of net rent. This type of expense does not appear in any gross yield displayed by a real estate listing.
Calculating gross yield and net yield: formulas and common pitfalls
The formula for gross yield is simple: (monthly rent x 12 / acquisition price) x 100. It gives a percentage that allows for quick comparison between two properties, but not for making a purchase decision.
The net yield requires subtracting from the annual rent all non-recoverable charges, property tax, management fees, and any planned works, then dividing the result by the total acquisition cost (property price, notary fees, agency fees).
Three common mistakes in investors’ spreadsheets
- Using the price displayed in the listing instead of the total acquisition cost, which includes notary and agency fees. The difference can exceed ten percent of the displayed price.
- Ignoring rental vacancy. One month without a tenant per year reduces the annual rent received by about eight percent, and this item never appears in the gross yield.
- Forgetting social contributions on rental income. In France, these social contributions represent 17.2% of net rental income, which significantly alters the final yield.
A property displayed with an attractive gross yield can drop significantly once these items are included. The gap between gross and net yield often exceeds two percentage points.
Energy performance diagnosis and Climate Law: the theoretical gross rent sometimes unattainable
Since the Climate and Resilience Law enacted on August 22, 2021, properties classified F and G in the energy performance diagnosis can no longer have their rent increased upon lease renewal or during a new rental in areas subject to rent control.
In practice, the gross rent listed in a simulation spreadsheet may be legally impossible to apply if the property is an energy sieve. From 2025, certain properties classified G will even be prohibited from rental, and this ban will gradually extend to properties classified F.
Concrete impact on net yield
To bring an energy-consuming property into compliance, energy renovation works (insulation, heating system replacement) become mandatory. These investment expenses, sometimes substantial, must be included in the calculation of net yield. A profitability simulation without projecting renovation works is misleading for a property classified F or G.
Two scenarios present themselves for the investor:
- Buying a property already renovated (DPE A to D), with a higher acquisition price but applicable gross rent without restrictions and limited work charges.
- Buying an energy-consuming property at a reduced price, incorporating the renovation budget into the total acquisition cost to recalculate a realistic net yield.
In the second case, the initial gross yield means absolutely nothing. Only the net yield after works provides a reliable picture of the rental investment.
Net-net yield: the calculation that includes real estate taxation
The net yield of charges is not enough to determine what actually remains in the landlord’s pocket. The net-net yield (or yield after tax) takes into account the chosen tax regime and the owner’s marginal tax bracket.
In unfurnished rentals, two regimes coexist: the micro-property regime, which applies a flat-rate deduction on gross rental income, and the real regime, which allows for the deduction of actual charges (loan interest, works, management fees). The choice between the two depends on the amount of deductible charges relative to rental income.
In furnished rentals, the micro-BIC regime and the real BIC regime offer depreciation mechanisms for the property that can significantly reduce the taxable base. The difference in net-net yield between the same property rented unfurnished or furnished can be significant, at the same gross rent.
The right reflex before any purchase: calculate the three levels of yield (gross, net of charges, net-net) on the same spreadsheet, incorporating the full acquisition cost, estimated rental vacancy, foreseeable works, and the chosen tax regime. A high gross yield that masks heavy taxation or imminent works does not protect the investor’s assets.
