Multifamily calculator

Compare unit rents and interior square footage, building expenses and financing. Income and expenses drive returns; square footage provides a separate comparison.

NOI means rental income after operating costs. Cash-on-cash means annual cash left over divided by all cash invested. Confirm that zero expense entries are intentional. NOI excludes loan payments, replacement reserves, depreciation and income taxes. Cash flow subtracts debt service and replacement reserves. The break-even estimate holds the modeled expense budget fixed. This is not a lender underwriting decision.

Illustrative assumptions only. Confirm rents, legal unit count, measured area, expenses and financing independently. No appreciation, sale proceeds or income tax effects are included.
