How the Rental Property ROI Calculator works


Comprehensive rental analysis: cash flow, cap rate, cash-on-cash return, and total ROI. Evaluate properties like professional investors.

Rental property builds wealth when chosen wisely. This calculator provides the analysis needed for success.

How it works

Tutorial

Rental property investment requires analyzing multiple return metrics simultaneously because each reveals different performance aspects. Simple ROI shows basic returns, cap rate indicates market value relative to income, and cash-on-cash return reveals leverage benefits. Professional investors analyze all three metrics plus appreciation potential, tax benefits, and mortgage principal reduction to understand complete investment performance.

You have two options: use the calculator above for comprehensive rental property analysis with all metrics, or follow this guide to manually calculate multiple ROI measurements.

The Formula

MetricFormula
Cash-on-Cash Return(Annual Cash Flow ÷ Cash Invested) × 100
Cap Rate(NOI ÷ Property Value) × 100
Total ROI(All Returns ÷ Investment) × 100
GRMProperty Price ÷ Gross Annual Rent

Step-by-Step Calculation

Let’s analyze a rental property using professional investor methods.

Step 1: Calculate Total Cash Investment

Determine all money invested upfront:

Investment ItemAmount
Purchase Price$275,000
Down Payment (25%)$68,750
Closing Costs$8,250
Initial Repairs$12,000
Reserves (3 months PITI)$4,500
Total Cash Invested$93,500

Calculation: $68,750 + $8,250 + $12,000 + $4,500 = $93,500

Step 2: Calculate Gross Rental Income

Determine total potential income:

Income SourceMonthlyAnnual
Base Rent$2,200$26,400
Pet Fees$50$600
Storage/Parking$75$900
Gross Rental Income$2,325$27,900

Calculation: ($2,200 + $50 + $75) × 12 = $27,900

Step 3: Calculate Net Operating Income (NOI)

Subtract operating expenses but not debt service:

Expense CategoryAnnual Amount
Gross Rental Income$27,900
Vacancy Loss (5%)-$1,395
Property Tax-$3,850
Insurance-$1,450
Maintenance (8%)-$2,232
Property Management (10%)-$2,790
HOA Fees-$1,200
Utilities (if owner-paid)-$0
Net Operating Income$14,983

Calculation: $27,900 – $1,395 – $3,850 – $1,450 – $2,232 – $2,790 – $1,200 = $14,983

Step 4: Calculate Cap Rate

Determine property performance independent of financing:

ComponentValue
Net Operating Income$14,983
Property Purchase Price$275,000
Divide NOI by price$14,983 ÷ $275,000
Capitalization Rate5.45%

Calculation: ($14,983 ÷ $275,000) × 100 = 5.45%

Step 5: Calculate Annual Cash Flow

Subtract mortgage payments from NOI:

ComponentAmount
Net Operating Income$14,983
Annual Mortgage Payment-$11,880
Annual Cash Flow$3,103

Calculation: $14,983 – $11,880 = $3,103

Step 6: Calculate Cash-on-Cash Return

Determine return on actual dollars invested:

StepCalculationResult
Divide cash flow by investment$3,103 ÷ $93,5000.0332
Convert to percentage0.0332 × 1003.32%

Calculation: ($3,103 ÷ $93,500) × 100 = 3.32%

Step 7: Add Wealth-Building Components

Include appreciation and principal reduction:

Return ComponentAnnual Amount
Cash Flow$3,103
Principal Paydown (Year 1)$3,420
Appreciation (3%)$8,250
Tax Benefits (estimated)$2,800
Total Annual Return$17,573

Calculation: $3,103 + $3,420 + $8,250 + $2,800 = $17,573

Step 8: Calculate Total ROI

Measure comprehensive return on investment:

StepCalculationResult
Divide total return by investment$17,573 ÷ $93,5000.188
Convert to percentage0.188 × 10018.8%

Calculation: ($17,573 ÷ $93,500) × 100 = 18.8%

Step 9: Calculate Additional Metrics

Determine Gross Rent Multiplier for comparison:

MetricCalculationResult
Gross Rent Multiplier$275,000 ÷ $27,9009.86
1% Rule Test$27,900 ÷ 12 ÷ $275,0000.84%

Reasoning: GRM of 9.86 is reasonable; property falls short of the 1% rule (rent = 1% of purchase price).

Final Answer: Cash-on-cash return is 3.32%, cap rate is 5.45%, but total ROI including all benefits is 18.8%

What This Means

While 3.32% cash flow return appears modest, the complete 18.8% total return reveals rental real estate’s true wealth-building power. The combination of cash flow, forced savings through principal reduction, appreciation, and tax advantages creates returns that significantly exceed what simple cash flow analysis suggests. This is why sophisticated investors focus on total return, not just monthly cash flow.
