| Scenario | Arbitrage margin | Markup | Net profit per month |
|---|---|---|---|
| $3k rev · $1.8k cost (40%) | 40.00% | 66.67% | $1,200.00 |
| $5k rev · $2.5k cost | 50.00% | 100.00% | $2,500.00 |
| $2.2k rev · $2k cost (thin) | 9.09% | 10.00% | $200.00 |
| $8k rev · $3k cost (luxury market) | 62.50% | 166.67% | $5,000.00 |
How This Calculator Works
Enter the monthly sublet revenue (net of platform fees) and your all-in monthly cost (rent + utilities + internet + supplies + cleaning + insurance + vacancy reserve). The calculator subtracts cost from revenue for net profit per month and divides by revenue for margin.
The Formula
Profit Margin and Markup
Markup = (Revenue − Cost) / Cost × 100 — the same profit measured against cost instead of revenue
Worked Example
A unit sublet for $3,000/month at $1,800 in all-in monthly cost posts a 40% margin and $1,200 of net profit per month. Across 12 months that's $14,400 per unit — strong unit economics that operators scale by adding units. The challenge is landlord permission and capital tie-up in furniture, deposits, and ramp-up.
Key Insight
Rental arbitrage margins look great per unit but require landlord permission (rare without explicit arbitrage clauses), high-vacancy weeks that eat into the average margin, and regulatory risk (many cities restrict short-term rentals). Successful operators usually focus on corporate housing or 30-day-minimum stays in regulated cities — both reduce regulatory risk and smooth occupancy compared to nightly bookings.

Frequently Asked Questions
How is rental arbitrage margin calculated?
Subtract monthly cost from monthly sublet revenue, then divide by revenue. $3,000 revenue at $1,800 cost is a 40% margin and $1,200 net profit per month.
What is rental arbitrage?
Leasing a property long-term and subletting it on short-term platforms (Airbnb, VRBO) or as corporate housing for the spread. No property purchase required — only the lease commitment, furnishing, and operating cost.
Do I need landlord permission?
Yes. Subletting without lease permission is a contract violation in most jurisdictions and grounds for eviction. Some landlords explicitly allow it in exchange for higher rent; specialty arbitrage-friendly landlords exist in some markets.
What's a typical margin?
Healthy arbitrage units run 30% to 50% margin. Below 25% rarely justifies the operational complexity. Margins compress fast when occupancy falls below 70% or local market saturates with new operators.
What's the biggest risk?
Regulatory risk. Many cities have restricted or banned short-term rentals (NYC, San Francisco, large parts of Europe). A regulation change can immediately destroy the arbitrage — operator owes lease but can't legally sublet. Diversifying into corporate housing or longer-stay reduces this risk.
When is this calculator unreliable?
Less reliable when city short-term rental regulations vary substantially (NYC effectively banned, SF 90-day, LA 120-day), when landlord prohibition violates lease (substantial eviction risk), when seasonal occupancy variance not averaged, when Airbnb fees + lodging taxes not deducted, when maintenance/repairs substantial for furnished STRs, or when furniture investment ($5K-$25K upfront) not amortized. Post-2022 'Airbnbust' yield compression substantial.

Methodology & Review
Rental arbitrage margin = (short-term rental revenue − long-term rent − fees − cleaning − supplies) / revenue. Calculator returns net + ROI. Typical 2024: rent $1,500-$3,000/mo; Airbnb gross $3,000-$8,000/mo (50% occupancy); net $500-$2,000/mo per unit after costs. Substantial city regulation + landlord permission risk. RELIABILITY: Reliable for documented actuals. Less reliable when (a) city short-term rental regulations vary substantially (NYC effectively banned, SF 90-day limit, LA 120-day, many cities permits required); (b) landlord prohibition (often violates lease); (c) seasonal occupancy variance; (d) Airbnb fees + taxes deducted; (e) maintenance/repairs (substantial for furnished STRs); (f) furniture investment $5K-$25K upfront.
