How We Calculate This
Cash Flow
Each year starts from your nightly rate across a full year, scaled by occupancy to get effective income, then subtracts operating expenses (management, the platform fee, property tax, insurance, HOA, maintenance, utilities, cleaning, supplies, and anything else) to reach net operating income (NOI). Cash flow is NOI minus your annual mortgage principal and interest. Income and expenses grow each year at the rates you set.
Cap Rate & Cash-on-Cash
Cap rate is first-year NOI divided by the purchase price, a financing-independent yield. Cash-on-cash return is first-year cash flow divided by the actual cash you put in (down payment plus closing and repair costs).
IRR & Total Profit
This projects each year's cash flow, then a sale at the end of your holding period: the appreciated value minus selling costs and the remaining loan payoff. Total profit sums your cash flow and net sale proceeds minus cash invested. IRR is the annualized return that accounts for the timing of every cash flow and the sale.
Short-Term Rental Calculator Formula
Net operating income for a year:
where effective gross income is scheduled rent minus vacancy, and operating expenses exclude mortgage principal and interest.
Capitalization rate:
expressed as a percentage.
Cash-on-cash return:
where total cash invested is down payment plus closing and repair costs.
