What does a rental property calculator actually measure?

It measures key financial metrics like net operating income, capitalization rate, cash flow, and cash-on-cash return based on your inputs for purchase price, financing, income, and operating expenses.

Can I use these calculators for commercial properties?

Yes, but you'll need to adjust the operating expense inputs. Most tools handle residential defaults but allow you to enter custom expense figures for any property type.

Do these tools factor in tax implications?

No, they focus on pre-tax cash flow and return metrics. Tax effects like depreciation and tax brackets require a separate analysis or software.

Is the internal rate of return (IRR) calculation accurate for short-term holds?

IRR assumes reinvestment of cash flows at the same rate, which may not reflect reality. For short-term holds, cash-on-cash return and simple cash flow projections are usually more reliable.

Why do results differ between calculators?

Differences come from how each tool handles vacancy rates, expense categorization, and whether they include or exclude taxes and insurance in the net operating income calculation.
