Situation
Example: a property bought for $220,000 with $15,400 in fees, $10,000 in works, $950 monthly rent and $4,700 yearly costs has gross yield = $11,400 ÷ $220,000 × 100 = 5.18%, while net yield must be read on the full project cost.
This page helps you analyze a rental investment before committing. The goal is not only to display an attractive percentage, but to understand what the property may really produce after expenses, vacancy, financing, works and local risk.
Net Yield = net annual income ÷ purchase price × 100
Gross yield compares annual rent with purchase price. Net yield subtracts recurring costs and relates net income to total project cost. Cash flow adds the monthly treasury view by comparing collected rent with expenses, loan payments and vacancy assumptions.

Read the result as a property decision aid, not a guaranteed return. A good net yield can become fragile if works are underestimated, vacancy rises, tax changes or financing absorbs the rental income.
The listing price is not enough. Acquisition fees, agency fees, works, furnishing, bank fees and a safety buffer should be included before judging profitability.
Gross yield divides annual rent by purchase price. Net yield subtracts expenses and gives a clearer view of what the owner may keep before full tax treatment.
Cash flow compares collected rent with monthly loan payment, charges, property tax, insurance, management, vacancy and maintenance. A fair yield can still require too much monthly effort.
Even a well-located property can remain empty between tenants. A vacancy assumption makes the simulation more resilient than a perfect twelve-month rental year.
Some costs can be charged to tenants while others remain with the owner. This distinction changes net income.
Loan duration, rate, down payment, borrower insurance and bank fees mainly affect cash flow and risk capacity.
Unfurnished rental, furnished rental, simplified regimes and actual expenses do not produce the same net result. A pre-tax estimate should not be treated as final.
Lower rent, higher costs and extra vacancy show whether the project remains robust when assumptions become less favorable.
A high yield can hide weaker demand or resale risk. A lower yield can be acceptable in a liquid and stable area.
Energy upgrades, roof, façade, heating and building expenses can materially reduce real return if they are not anticipated.
Before keeping the result, review the inputs as a set rather than as isolated fields. An annual period paired with a monthly rate, a gross amount compared with a net amount or one currency mixed with another can create an output that looks clean but is not usable. This basic check helps prevent decisions built on an unstable base and makes the comparison easier to explain afterward.
Identify the input that drives the output the most, then change only that value while leaving the rest of the model unchanged carefully. This method shows whether the calculation mainly depends on the rate, duration, price, volume, return or recurring cost. When the result moves sharply after a small adjustment, keep a wider safety margin and avoid presenting the number as a final conclusion.
A calculator provides a structured estimate, not an automatic validation of the project. Compare the result with an invoice, statement, quote, local rule, personal history or operating constraint. The useful question is whether the order of magnitude still looks plausible once it is placed back into the situation you are trying to solve, with the same constraints and timing.
Write down the date, entered values, units, rounding and selected scenario. This record makes the calculation easier to repeat later, explains why two outputs differ and supports a clearer discussion with an adviser, customer, relative or colleague. Without a record, even a useful simulation can become hard to verify when the context, assumptions or source data change later.
The same property can look strong on gross yield and much tighter after costs, expenses and financing.

Slightly higher rent, controlled costs and low vacancy. This shows potential, but should not be the only decision case.
The central case based on comparable rents, known costs and normal vacancy. Use it as the decision baseline.
Lower rent, higher costs and more vacancy. The project should remain acceptable in this stress test.
Checks whether works really improve rent, value and ease of letting.
Shows whether retained income remains coherent once the selected tax regime is considered.
Rental Yield is a real-estate estimate. Expenses, repairs, vacancy, financing, local taxes, acquisition costs and market changes can alter the result.
Gross yield divides annual rent by purchase price. Net yield subtracts expenses and relates net income to the total project cost for a more realistic reading.
Gross yield only uses rent and purchase price. Net yield includes expenses such as property tax, insurance, vacancy, management and sometimes works.
It depends on the city, risk, property type, rental demand and investor goal. A high yield is not always better if the risk is high.
Monthly cash flow is rent collected minus loan payments, expenses, insurance, property tax, management, estimated tax and maintenance.
Yes. They are part of the real project cost and excluding them overstates profitability.
Yes. Initial and foreseeable works increase capital committed and can reduce starting yield.
It ignores expenses, financing, tax, vacancy, works and acquisition costs, so it can look too favorable.
Negotiate price, reduce recurring costs, limit vacancy, improve property quality, adapt rental strategy or optimize financing.
No. Location, energy rating, works, building costs, tax, financing, tenant demand and resale liquidity must also be reviewed.
No. It is an estimate based on your assumptions. Real rents, costs, works, tax, financing and market conditions can change the outcome.
