Free Online ConsultationStart Your Minpaku Revenue Simulation with These 3 Key Numbers
When calculating a revenue simulation for your minpaku (vacation rental) business, the first numbers you need to nail down are “occupancy rate,” “ADR (Average Daily Rate),” and “total expenses.” Without all three in place, you simply can’t form a reliable picture of your actual take-home income. At Stay Buddy, whenever we take on property management for an owner, our very first step is sharing projections built around these three pillars. Much of the “earn X amount per month” content you see online tends to be overly optimistic on one of these three factors—or significantly underestimates expenses.
The Core Metrics Behind Your Revenue Simulation
A Realistic Look at Occupancy Rate
Occupancy rate is the percentage of operable days that are actually booked. For properties registered under the Private Lodging Business Act (the “Minpaku Act”), the annual operating cap is set at 180 days (Article 3, Paragraph 1 of the Act), and this ceiling directly affects the denominator used to calculate occupancy. According to the Japan Tourism Agency’s latest published report on private lodging business operations, the average occupancy rate across registered properties nationwide is far from high, and varies enormously depending on location, property type, and price range. In reality, properties in high-demand tourist areas can see occupancy rates above 80–90% during peak season, while the same properties might drop to just 20–30% in the off-season. Looking at the annual average, even well-positioned properties typically land somewhere in the realistic range of 40–65%.
How ADR (Average Daily Rate) Is Determined
ADR (Average Daily Rate) is the average per-night price across actual confirmed bookings. It’s typically set by researching competitor pricing on OTAs (online travel agencies) like Airbnb or Rakuten Travel, then adjusting based on your property’s size, amenities, and location. Adjusting rates seasonally through “dynamic pricing” is key to improving revenue—but get it wrong, and your occupancy can actually suffer. In our own experience, we once saw a newly opened property set an overly aggressive rate from day one, resulting in zero reviews for the first three weeks and an occupancy rate that fell below 10%. We temporarily matched the lowest price point among nearby competitors to build up reviews, then gradually raised rates again the following month. The “right” price point shifts depending on the balance between competitor pricing and your own property’s review standing.
The Revenue Formula
The basic formula for monthly revenue is “booked days × ADR.” For example, with 30 operable days, a 50% occupancy rate, and an ADR of ¥15,000 per night: 15 days × ¥15,000 = ¥225,000 in monthly gross revenue. Subtracting OTA fees (for Airbnb, host-side fees are deducted as a percentage of each booking’s total, with the exact rate depending on specific conditions) from this figure gives you your “net revenue.” Be sure to check the current fee structure in each OTA’s host terms, since even published rates can vary based on applicable conditions.
Expense Breakdown: Fixed Costs That Are Easy to Overlook
Cleaning Costs
Cleaning fees, incurred after every checkout, typically range from ¥3,000 to over ¥10,000 per visit, depending on property size and who you contract with. Securing reliable cleaning staff is directly tied to operational stability. On one property we took over from another management company, we discovered the cleaning contract hadn’t actually been transferred—leaving cleaning arrangements completely unresolved the night before opening day. We scrambled to arrange staff on short notice, but if cleaning gets interrupted during peak season, you simply can’t accept the next guest, which hits your occupancy rate directly. Cleaning costs are a variable expense that scales with occupancy, so in your simulation, calculate them as “per-visit cost × monthly checkout count.”
Supplies and Amenities
Consumables like toilet paper, shampoo, laundry detergent, and coffee fluctuate with guest count and length of stay. Many operators budget roughly 5–10% of monthly revenue for this, though properties hosting larger groups or marketing premium amenities should expect this to run higher.
Platform and Management System Fees
Beyond OTA commissions, if you’re using a channel manager or PMS (property management system) to centrally manage multiple platforms, expect an additional cost of a few thousand to several tens of thousands of yen per month. As your operation scales, manual management eventually hits its limits—so tool costs should be budgeted as a necessary investment, not an afterthought.
Utilities and Internet
Electricity, water, gas, and Wi-Fi all carry base charges even during periods with no guests, making them quasi-fixed costs. Spending doesn’t drop much even in low-occupancy months, so it’s most realistic to budget these as a fixed monthly amount in your simulation.
Property Management Fees (If Applicable)
If you outsource operations to a management company, it’s standard to pay a percentage of revenue as a fee. This percentage varies by company and scope of service, but a range of 15–30% of revenue is often cited as a general benchmark. That said, actual costs depend heavily on what’s included—pricing strategy, cleaning coordination, guest communication, licensing support, and so on.
Depreciation and Equipment Replacement
Furniture, appliances, and bedding wear out over time. Separate from recovering your initial investment, if you don’t factor in equipment replacement costs on a multi-year basis, you’ll end up overestimating your actual take-home income. A practical approach is to build a monthly “reserve fund” amount into your simulation.
A Sample Simulation: Calculating Net Take-Home Income
The example below is intended purely to illustrate the structure of a simulation—it does not guarantee actual earnings. Results will vary significantly depending on your specific conditions.
| Item | Amount (Example) |
|---|---|
| Monthly gross revenue (15 booked days × ¥15,000) | ¥225,000 |
| OTA fee (assumed: 15% of revenue) | －¥33,750 |
| Cleaning fees (15 visits × ¥5,000) | －¥75,000 |
| Supplies and amenities | －¥15,000 |
| Utilities and Wi-Fi | －¥20,000 |
| System fees and other costs | －¥10,000 |
| Property management fee (assumed: 20% of revenue) | －¥45,000 |
| Monthly net income (estimated) | Approx. ¥27,000 |
This example shows that even with a 50% occupancy rate and an ADR of ¥15,000, your actual take-home can shrink to just a few tens of thousands of yen depending on your expense structure. Simply raising your ADR to ¥20,000, or improving occupancy to 70%, can dramatically shift your bottom line. On the flip side, if you start operating without a clear grasp of cleaning costs or management fee structures, you can end up in a situation where revenue climbs but your actual take-home doesn’t budge.
Key Assumptions You Must Confirm Before Running Your Simulation
When calculating a minpaku revenue simulation, the single biggest factor shaping your numbers is “which legal framework you’re operating under.” Under the Private Lodging Business Act (Minpaku Act), the 180-day annual cap becomes the hard ceiling on your occupancy rate. If you instead hold a simple lodging business license under the Hotel Business Act, there’s no such day limit, which changes the maximum achievable occupancy entirely. Initial costs for meeting fire safety equipment standards (such as automatic fire alarms and emergency lighting) also differ depending on which framework you choose. There’s no one-size-fits-all answer to “which option is better”—it depends on your property’s structure, location, and local municipal regulations—but whichever framework you choose, make sure it’s confirmed before you set the occupancy ceiling used in your simulation.
