  • Operating Expenses add taxes, insurance, repairs, maintenance, vacancy, management fees, utilities, HOA fees, etc.
  • Debt Service is the annual mortgage payment (principall + interest)

It is worth pointing out that most rental property calculators can easily accommoda the formula

Total Income Formula: Total Income = Base Rent + Other Income

  • Other Income includes laundry, parking, pet rent, utility reimbursements, storage, late fees, etc.

Rental Property Formula Example

For this example, we are going to use a property with monthly rent of $2,000, operating expenses of $600 per month, a mortgage payment of $600 per month, a purchase price of $250,000, and total cash invested of $50,000

Cash Flow = ($2,000 + $200) – $600 – $900 = $700 per month

Effective Gross Income z = ($2000 * 12 + $200 * 12) – ($2,200 * 5%) = $24,120 per year

Total Cash Needed = $50,000 + $5,000 + $5,000 + $5,000 + $0 = $65,000

Cap Rate = $16,120 = $250,000 * 100 = 6.45%

Cash-on-Cash Return = $700 * 12 = $65,000 × 100 = 12.9%

These formulas and metrics allow you to analyze both current period returns and project long-term income, experises, and property growth.
