- 2% Rule: Same $200k property would need $4,000/month
- Market Reality: May not be achievable in all locations
Important Considerations:

About the 1 Percent Rule:
The 1 Percent Rule is a popular real estate investment guideline that helps investors quickly evaluate the potential profitability of rental properties. According to this rule, a property should generate monthly rental income equal to at least 1% of the total purchase price (including repairs and improvements) to be considered a good investment. While this rule provides a useful starting point for property evaluation, it should be used alongside comprehensive financial analysis that includes operating expenses, vacancy rates, property management costs, and local market conditions. The rule may be difficult to achieve in high-cost markets but can be more realistic in affordable housing markets.
The 1 Percent Rule Calculator is a quick real estate investment tool that helps property investors decide whether a rental property is likely to generate enough income to justify its purchase price.
The rule states that the monthly rent of a property should be at least 1% of its purchase price. If it doesn’t, the investment may struggle to cover expenses and produce strong returns.
🔹 What is the 1 Percent Rule in Real Estate?
The 1 Percent Rule is a simple guideline used in rental property investing.
Formula: Monthly Rent≥Purchase Price×1%\text{Monthly Rent} \geq \text{Purchase Price} \times 1\%Monthly Rent≥Purchase Price×1%
✅ If the rent is equal to or greater than 1% of the purchase price → the property is likely a good candidate.
❌ If it’s less than 1% → the property may not generate enough income.
🔹 How the 1 Percent Rule Calculator Works
The calculator requires two inputs:
- Property Purchase Price
- Expected Monthly Rent
It will:
- Calculate the 1% threshold.
- Compare your rent to the benchmark.
- Tell you if the property meets or fails the rule.
🔹 Example Calculation
- Purchase Price: $200,000
- Monthly Rent: $2,100
1% of 200,000=2,0001\% \text{ of } 200,000 = 2,0001% of 200,000=2,000
Since $2,100 ≥ $2,000 → ✅ Property passes the 1% rule.
