The Only Vacation Rental Revenue Formula That Works
Most "vacation rental revenue calculators" online ask for a nightly rate and an occupancy percentage you have to guess, then hand you a number that is only as good as your guesses. This guide gives you the real formula, shows you where to get honest inputs, and works a live 2026 example end to end.
The formula is simple and non-negotiable:
- RevPAR = ADR × Occupancy — revenue per available night.
- Monthly revenue = RevPAR × 30
- Annual revenue = RevPAR × 365
Everything else — cleaning fees, seasonality, length-of-stay discounts — is a refinement on top of this core. Get the two inputs (ADR and occupancy) right for the specific market, and your projection will be defensible. Get them wrong, and no amount of spreadsheet detail will save it.
A Live 2026 Example: Scottsdale, AZ
Using current STRmetrics data for Scottsdale (week of July 2, 2026):
- Median ADR: $256/night
- Forward occupancy: 34%
- RevPAR = 256 × 0.34 = $88
- Monthly revenue ≈ 88 × 30 = $2,640 per active listing
- Annual revenue ≈ 88 × 365 = $32,120 per active listing
Notice what this exposes: Scottsdale's headline $256 ADR looks like a premium market, but its 34% forward occupancy pulls annual revenue down to roughly $32k per listing. That is the whole point of the formula — it stops you from over-projecting off a big rate.
Market Choice Dominates the Output
The same calculation across other live markets shows how much the city — not the finishes or the photos — drives revenue:
- Miami, FL: ADR $176 × 74% occ = $131 RevPAR ≈ $47,815/yr per listing.
- Denver, CO: ADR $130 × 69% occ = $90 RevPAR ≈ $32,850/yr.
- Scottsdale, AZ: ADR $256 × 34% occ = $88 RevPAR ≈ $32,120/yr.
- Nashville, TN: ADR $153 × 21% occ = $32 RevPAR ≈ $11,680/yr.
Miami out-earns Nashville roughly 4-to-1 per listing on the same math — driven almost entirely by forward occupancy. A calculator is only as honest as the market data you feed it.
The Three Mistakes That Ruin the Number
1. Using peak-season ADR. A $400 July rate is not the year-round figure. Use the median ADR across live listings.
2. Guessing occupancy. This is the input people fabricate most. Use forward occupancy from a real sample, not optimism.
3. Using stale data. STR demand moves monthly; a projection built on last year's figures will miss.
Run the Calculator on Live Data
Instead of typing guesses into a generic calculator, pull the real ADR and occupancy for your exact market from STRmetrics, then apply the formula above. You can start a free 7-day trial and get live inputs for any city — ideal for owner quotes, acquisition underwriting, or a management pitch you actually want to stand behind.
Beyond Gross Revenue: What the Calculator Doesn't Show
The RevPAR formula gives you gross revenue per listing. To get to what actually lands in your pocket, subtract the real cost stack: platform fees (typically 3%), cleaning (often passed through but not always), management (20–30% of gross for a full-service PM), supplies, utilities, insurance, and debt service if the property is financed. On a Scottsdale unit grossing ~$32,120/year, a 25% management fee alone is roughly $8,000 — so net-to-owner math has to start from an honest gross, which is exactly why the input data matters so much.
Frequently Asked Questions
How accurate are online vacation rental revenue calculators?
Only as accurate as their two core inputs — ADR and occupancy. A calculator that asks you to guess those, or that uses a stale national dataset, will produce a confident-looking but unreliable number. Feed it live, city-specific median ADR and forward occupancy and the same formula becomes genuinely defensible for an owner quote or a lender.
What occupancy rate should I plug in?
Never a round guess like "70%." Use the current forward occupancy for the exact city and property type. In our live sample that ranges from 21% (Nashville) to 74% (Miami) — a swing that changes annual revenue by tens of thousands of dollars per listing. The occupancy input, not the rate, is where most projections go wrong.
Key Takeaways
- Revenue = ADR × Occupancy × days. There is no shortcut around getting those two inputs right.
- A high ADR means nothing without occupancy — always project on RevPAR.
- Market selection swings per-listing revenue by 3–4x; validate the city, not the vibe.
- Feed the formula live data — start a free 7-day trial to pull current ADR and occupancy for any market.
