An NOI calculator is an essential tool for real estate investors, designed to calculate a property’s net operating income. It does this by subtracting the property’s operating expenses from its total income. Operating expenses include things like property management fees, maintenance costs, insurance, property taxes, and utilities. What remains is the NOI, which reflects the true earning potential of the property, excluding any debt service, taxes, or depreciation.
