The price on a listing, the guest’s total bill and the amount the owner keeps are three different figures. To assess your project, start by separating nightly revenue, charges for the stay and the property’s running costs.
1. Start with the nights actually booked
Choose a period and count the nights actually booked. Multiply that number by the average rate for those nights, allowing for discounts and refunds. A rate displayed for one night does not necessarily apply to every date on the calendar.
Then compare that revenue with the nights you actually offered. Personal stays and closures shorten the letting period. An estimate based on twelve months of availability will not reflect the situation of an owner who lives in the apartment for part of the year.
2. Apply the commission to the correct amount
Baytt charges a management fee of 18% of the nightly charges, including VAT. To understand the cost, distinguish the amount used to calculate the commission from platform fees, cleaning, tourist tax and additional services. Your contract and statements should let you reconcile the figures without deducting anything twice.
If the nightly charges on which the commission is calculated total €2,000, an 18% management fee comes to €360. That leaves €1,640 before other fees and running costs. That figure is therefore not the owner’s net income.
If the platform pays you after deducting its fees, do not subtract them again. Reconstruct the breakdown from the booking statement and reconcile it with the management invoice. If the figures differ, ask how they were calculated. Comparing two bank transfers alone will not explain the difference.
3. List the other costs separately
| Cost item | Question to ask |
|---|---|
| Platforms | What fees does the platform retain, and have they already been deducted from the payout? |
| Cleaning and linen | How much does each changeover cost, who pays for it and how much is charged to the guest? |
| Supplies and maintenance | What purchases and replacements were needed during the period? |
| Property running costs | How much should you allow for energy, internet, insurance and other property costs? |
| Financing and tax | Which figure do you need: operating profit, cash flow or income after tax? |
A cleaning fee on the guest’s bill does not automatically represent profit. It may pay for a service. Likewise, set aside any amounts collected on behalf of third parties so you do not overstate what is yours.
4. Define exactly what your figure represents
Operating profit after the costs of each stay differs from cash flow after loan repayments. Neither necessarily equals income after tax. Choose a measure, write down what it includes and use the same method to compare months.
Use three columns: rental receipts, related expenses and the balance as you have defined it. Add the dates and flag one-off expenses. Include the cost of replacing equipment, but identify it separately so you can explain differences between months.
5. Test several scenarios before deciding
For a first letting, prepare a cautious, a middle and a more favourable estimate. Vary the average rate and number of nights booked while keeping the costs you incur even without bookings. Consider shorter average stays, too. The same number of booked nights will require more changeovers.
Use the scenarios to decide whether the arrangement suits you and which assumptions to monitor. The highest projected figure is of little use on its own. Ask a qualified professional to confirm the accounting and tax treatment for your circumstances.
