  • Results may be rounded for readability, while the calculator keeps greater precision internally.
  • Real-world measurements and assumptions can introduce small differences from the calculated estimate.

Common uses

  • Estimate new rent
  • Compare percentage changes
  • Plan lease renewals

Assumptions

What this calculation assumes

  • Local taxes, financing, insurance, vacancy, maintenance, and closing costs can change results.
  • Rent, value, and appreciation assumptions should match the same property and period.
  • Inputs are assumed to describe the same scenario and use compatible units.
  • Results may be rounded for readability.

Avoid mistakes

Quick checks before you rely on the result

  • Using gross rent when net rent is required.
  • Ignoring vacancy, maintenance, financing, tax, or closing costs.
  • Mixing units, periods, currencies, or measurement systems without converting first.
  • Rounding intermediate values too early.
