Methodology, Model Assumptions & Statutory Rules
SolveItCalculator strictly separates mathematical equations, baseline assumptions, current statutory rules, and general financial planning information.
1. Deterministic Calculator Math
Cap Rate = Net Operating Income (NOI) ÷ Current Market Value. Cash-on-Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested. NOI = Gross Rental Income - Operating Expenses (excluding debt service).
2. Model Assumptions
- Vacancy rates and credit losses are modeled as a percentage deduction from gross potential rent.
- Cap rate excludes mortgage debt service to measure pure property asset yield.
3. Current Statutory / Tax Rules
- IRS Section 1031 Exchange allows real estate investors to defer capital gains tax by rolling sale proceeds into a like-kind replacement property.
- Residential rental property depreciates over 27.5 years under MACRS (Modified Accelerated Cost Recovery System).
4. Financial Information & Principles
- The 1% Rule states that a rental property should generate monthly rent equal to at least 1% of the purchase price for likely positive cash flow.
- Cap rate reflects unleveraged yield and local market risk; Cash-on-Cash return reflects actual equity performance with mortgage financing.

Cap Rate vs. Cash-on-Cash Return in Real Estate Investing
Understand the critical difference between evaluating property value versus measuring investor equity return.
Governing Formula
Cap Rate = NOI / Property Value | Cash-on-Cash = Cash Flow / Cash InvestedWorked Example: $300,000 rental property purchased with 20% down ($60,000 + $5,000 closing costs). NOI = $24,000/yr. Annual Mortgage Payments = $16,000/yr.
Calculation: Cap Rate = $24,000 / $300,000 = 8.0%. Annual Cash Flow = $24,000 - $16,000 = $8,000. Cash-on-Cash Return = $8,000 / $65,000 = 12.31%.
Result: 8.0% Cap Rate | 12.31% Cash-on-Cash Return
Key Takeaway: Favorable mortgage leverage can boost your cash-on-cash yield significantly above the property’s baseline cap rate.
