The mortgage on an apartment may look affordable. Then the owners’ association contribution, energy bill and local taxes arrive. How much do you actually need each month?
Monthly apartment costs include the mortgage, owners’ association, utilities, taxes, insurance and private maintenance. Our fictional example comes to €2,062 a month, before your personal income tax effect. This is a budget illustration, not a Dutch average. It concerns an owner-occupied apartment in the Netherlands. Sources and tax rules were checked in October 2026.
Monthly apartment costs: a complete example
Assume you buy an existing apartment for €300,000 and borrow the full amount. The loan is an annuity mortgage: monthly payments combine interest and repayment. We assume a 30-year term and fictional annual interest of 4%, calculated monthly. This is not a current mortgage offer.
The VvE contribution includes building insurance, shared maintenance and management. Heating and drinking water are billed separately. There is no ground rent, rented parking space or VvE loan. Every other amount below is also an illustrative assumption, not a researched average or quotation.
| Item | Per month |
|---|---|
| Mortgage interest and repayment | €1,432 |
| VvE, including shared maintenance and building insurance | €250 |
| Energy for your apartment | €130 |
| Drinking water | €20 |
| Municipal and water board taxes | €100 |
| Personal contents and liability insurance | €20 |
| Internet | €40 |
| Reserve for private maintenance | €70 |
| Total before personal income tax effect | €2,062 |
You therefore need €630 beyond the mortgage each month. Some of that money goes into reserves rather than being spent immediately. Groceries, health insurance, transport, mobile service and leisure are excluded. Purchase costs and furnishing also need a separate budget. No assumed tax refund has been deducted.
Mortgage: include the full payment
The example payment is approximately €1,432. In the first month, €1,000 is interest (€300,000 × 4% ÷ 12) and about €432 repays the debt. Repayment builds equity, but you still need the cash every month.
With an annuity mortgage, the payment stays level while the interest rate stays unchanged. The interest share gradually falls and the repayment share rises. With a linear mortgage, the principal repayment stays constant and interest declines at an unchanged rate. Check the payment schedule for your actual loan.
Your deposit also matters. Borrowing €250,000 under the same assumptions gives a payment of about €1,194. You would need an extra €50,000 of your own money, alongside purchase costs and emergency savings.
Gross payments and tax relief are different
Mortgage interest may qualify for tax deduction under conditions. Principal repayments are not interest. Do not deduct a tax percentage from the whole monthly mortgage payment.
There is also the eigenwoningforfait, an addition to taxable income for an owner-occupied home. A €300,000 WOZ value, the official assessed property value, produces a €1,050 annual addition under the 2026 table. That is not a separate €1,050 bill.
Have the combined effect calculated for your own income and loan. If a provisional refund already appears in your monthly income, do not subtract it again from housing costs. Recheck it when your circumstances change.
VvE: find out what is included
Apartment owners belong to the Vereniging van Eigenaars, or VvE, the owners’ association. It manages the shared parts of the building. Ask for a breakdown of your contribution rather than relying on the total in the sales listing.
Shared heating, water or payments on an association loan may be included. If they are, they affect what you need to add separately. Building insurance and communal maintenance are already included in our example contribution.
Read the multi-year maintenance plan, called an MJOP, alongside the accounts, reserves and meeting minutes. A cheap contribution can leave expensive work unfunded. The VvE must reserve for major maintenance using a maintenance plan or at least 0.5% of rebuilding value annually. That rule concerns the building’s reserve, not your complete personal contribution.
Your share of an extra bill follows the applicable allocation rules. Do not simply divide by the number of apartments. Our guide to the monthly VvE contribution explains what documents to request.
Energy and water: avoid counting heating twice
An energy advance is a payment towards the final bill. Ask for annual consumption, the heating system and insulation details. The seller’s monthly advance alone is a weak starting point.
Milieu Centraal identifies dwelling type and household size as factors in consumption. A national average cannot predict your individual bill.
A private gas boiler means gas and electricity bills. District heating uses a different tariff structure. An all-electric apartment has another consumption pattern. Compare the complete annual cost, including fixed charges, rather than one unit price.
With communal heating, a heating advance may already sit inside the VvE payment. Add only separately billed electricity and any expected settlement. Do the same check for drinking water. The annual energy statement guide explains how advances and actual costs relate.
Water board tax is separate from drinking water. Paying the water company does not replace the tax assessment.
Taxes: turn annual assessments into monthly reserves
Municipal rates change annually. Use the assessments for your address and household. OZB is property tax based on the WOZ value and the municipal rate. Waste collection and sewer charges may also apply. Local rules determine how sewer charges fall on owners and users.
The 2026 water board overview lists resident, built-property and wastewater treatment charges for owner-occupiers. Check your own assessment for other applicable charges.
Our €100 monthly assumption means €1,200 a year for municipal and water board taxes together. It is fictional. Replace it with your actual annual total divided by twelve. See taxes for Dutch homeowners and tenants for the distinction from income tax.
An assessment collected in ten instalments has a higher debit than its twelve-month average. Reserve for the whole year, and avoid counting both the reserve and the payment as separate expenses.
Insurance and maintenance inside your apartment
Check the VvE building policy before buying duplicate cover. Contents insurance protects belongings. Ask about eigenaarsbelang, cover for privately added improvements. Vereniging Eigen Huis explains the distinction.
Keep private maintenance separate from communal maintenance. Appliances, interior decorating and private installations can need replacement. The division deed and regulations determine which parts belong to which responsibility.
Our €70 reserve builds €840 a year. It is not a maintenance standard. An ageing bathroom or boiler may require substantially more. Estimate likely work and timing rather than copying the example.
Ground rent, parking and overlooked costs
Erfpacht means using land owned by someone else, potentially for a periodic fee called canon. Check whether it has been bought out, for how long and how future charges are set. Eigen Huis highlights possible increases.
Include parking, permits or a separately charged storage unit where relevant. Use the normal internet tariff after any introductory offer.
Suppose apartment A has a €150 lower mortgage payment than B, but costs €100 more in VvE and €75 in ground rent. With everything else equal, A is €25 more expensive each month. Compare total costs and included services.
Test a more expensive month and a one-off bill
A €50 VvE increase and €40 energy increase would take our budget to €2,152. Can you cover that while meeting other necessary expenses?
For a separate interest illustration, a new €300,000 loan over 30 years costs about €1,610 monthly at 5%, compared with €1,432 at 4%. The €178 difference is not a forecast for your reset date. Your remaining debt and term then determine the payment.
An unexpected €3,000 maintenance share needs accessible money. Raising a future monthly reserve will not pay a bill due now. Keep a cash buffer alongside your regular budget.
Purchase costs and renting are separate calculations
Government guidance lists purchase expenses such as notary, valuation and possible inspection fees. Add mortgage advice, moving, furnishing and immediate repairs where applicable. Obtain quotations and keep the required money available at payment time.
You can spread one-off costs over sixty months to compare five-year ownership scenarios. That does not change when the original bills must be paid.
If you rent, start with basic rent and itemised service charges instead of a mortgage and your own VvE contribution. Owner charges differ. Do not reuse the ownership example unchanged.
