Calculating rental yield: from purchase price to realistic income
A rental yield becomes useful when you know which rent, costs and investment amount it includes. Two identical percentages can describe very different calculations. A simple bridge from gross to net figures makes property offers easier to assess.
At a glance
- Gross rental yield compares annual rent excluding service charges with the purchase price.
- A net calculation needs acquisition costs and explicitly identified owner costs.
- Financing, tax and changes in value require separate analysis.
Start with gross rental yield
Gross rental yield divides annual rent excluding service charges by the purchase price. Operating cost advances do not belong in the numerator because corresponding expenses offset them. For an occupied apartment, start with the current contractual rent. A proposed rent for a new tenancy belongs in a separate scenario, with evidence for both the amount and the timing.
Record the full acquisition outlay
In this example, an apartment costs €240,000, with assumed acquisition costs of €24,000. This is an illustrative amount, not a universal percentage: transfer tax, notary, land register and any brokerage fees must be established for the particular purchase. Necessary work immediately after purchase also needs a clear place in the investment budget.
At €900 monthly rent excluding service charges, annual rent is €10,800 and gross rental yield is 4.50%. Even before recurring costs, the ratio falls to 4.09% when the same rent is compared with the full acquisition outlay of €264,000. Always display the denominator alongside the percentage.
Move from rent to the planned operating surplus
For our net measure before financing and income tax, deduct owner costs that cannot be recovered from the tenant and explicit allowances for maintenance and rent loss. The market uses “net” in different ways. The disclosed calculation matters more than the label.
An allowance is not yet a paid invoice. The maintenance assumption must reflect the building and apartment. If it already includes funding the same work through the owners’ association reserve, do not deduct that amount a second time.
| Item | Amount |
|---|---|
| Annual rent excluding service charges | €10,800 |
| Owner costs | −€960 |
| Maintenance allowance | −€720 |
| Rent loss allowance | −€864 |
| Planned surplus | €8,256 |
Assumptions determine whether comparisons work
The 3.13% describes the property within this model. It does not tell you what remains in your account after loan payments. Interest and principal repayment are added in a separate financing and liquidity calculation. Expected appreciation does not increase the current net rental yield either.
Compare offers using the same rules and calculate a more cautious case: a period without rent, higher maintenance or an anticipated rent increase that never occurs. If an offer looks attractive only under optimistic assumptions, that dependence is part of the purchase decision. A single yield percentage cannot replace checking the building or reviewing the tenancy agreement.
