Real Estate ROI Calculator

Introduction

A real estate ROI calculator helps you estimate whether a rental property generates enough income to justify the upfront purchase and ongoing costs.

Enter purchase price, closing costs, annual rental income, maintenance, property tax, and holding period. The tool computes profit, ROI %, annualized ROI, and break-even, plus a visual cost breakdown.

Formulas

Acquisition cost = Purchase price + Closing costs
Total rent = Annual rental income × Holding years
Total expenses = (Maintenance + Property tax) × Holding years
Profit = Total rent − Total expenses − Acquisition cost
ROI % = Profit ÷ Acquisition cost × 100
Annualized ROI % = ((1 + Profit ÷ Acquisition cost)^(1 ÷ Holding years) − 1) × 100

Break-even is shown only when cumulative net rent covers acquisition cost within the holding period and profit is zero or positive.

Financial terms explained

Read each formula label below in plain language before you enter numbers.

Input terms

Term	Meaning
Purchase price	The contract price to buy the property — land and building — before closing fees.
Closing costs	One-time cash paid at purchase (title insurance, escrow, attorney, recording fees, points, etc.). In this tool they are added to purchase price as upfront cash invested.
Rental income (annual)	Gross rent you collect in one year before subtracting expenses. Enter the yearly amount; the tool multiplies by holding years for total rent.
Maintenance (annual)	Average yearly upkeep: repairs, landscaping, HOA fees, small replacements, and routine property care.
Property tax (annual)	Government tax assessed on the property each year. Enter the yearly bill; the tool scales it across the holding period.
Holding period (years)	How long you plan to own and rent the property. Used to convert annual rent and expenses into totals and to compute annualized ROI.

Derived terms (used inside the formulas)

Term	Formula	Meaning
Acquisition cost	Purchase price + Closing costs	Total cash you put in at the start before collecting rent. This is the denominator for ROI %.
Total rent	Annual rental income × Holding years	All gross rent collected over the full holding period.
Total expenses	(Maintenance + Property tax) × Holding years	All operating costs over the holding period (this tool does not include mortgage, insurance, or vacancy).
Net rent (operating cash flow)	Total rent − Total expenses	Cash left from rent after operating costs, before recovering acquisition cost.

Result terms

Term	Formula	Meaning
Profit	Total rent − Total expenses − Acquisition cost	Net gain or loss from rental cash flow versus money invested upfront. Does not include selling the property or appreciation.
ROI %	Profit ÷ Acquisition cost × 100	Return on upfront cash. Example: 20% ROI means you gained $0.20 for every $1.00 invested at purchase.
Annualized ROI %	((1 + Profit ÷ Acquisition cost)^(1 ÷ Years) − 1) × 100	Average yearly return rate so you can compare properties held for different lengths of time.
Break-even	Acquisition cost ÷ (Net rent ÷ Holding years) when net rent > 0	Estimated years until cumulative net rent recovers acquisition cost. Shown only when profit ≥ 0 at the end of the period.

Quick example

Purchase $300,000 + Closing $15,000 → Acquisition cost $315,000.
Annual rent $24,000 × 5 years → Total rent $120,000.
(Maintenance $3,000 + Tax $4,000) × 5 → Total expenses $35,000.
Profit = $120,000 − $35,000 − $315,000 = −$230,000 (rent alone did not recover purchase + closing over 5 years).

When to use this tool

• Compare rental properties before you buy
• Estimate cash-flow recovery on a down payment plus closing costs
• Present simple ROI figures for a rental listing or partnership
• Teach how rent, taxes, and maintenance affect property returns

Limitations

This tool does not include mortgage payments, insurance, vacancy, capital improvements, sale price, or tax benefits. Use a full rental property spreadsheet or IRR tool for financed or appreciation-based scenarios.
