How to use this calculator
- Select a display currency; this changes the symbol only, not exchange rates.

Input definitions
- Sale price: Gross selling price.
- Selling expenses: Selling costs that reduce amount realized.
- Original purchase price: Original cost basis before adjustments.
- Capital improvements: Qualifying capital improvements added to basis.
- Basis reductions: Depreciation or other reductions to adjusted basis.
Formula and calculation method
Amount realized = sale price − selling expenses. Adjusted basis = purchase price + capital improvements − basis reductions. Estimated gain = amount realized − adjusted basis.
The engine keeps the calculation transparent and separates operating performance from financing where required. NOI, cap rate, cash flow, DSCR and seller proceeds answer different questions and should not be treated as interchangeable measures.
Understanding the result
Use the output as a planning estimate and compare it with property-specific documents. Buyers should verify lender estimates, taxes, insurance and inspections. Investors should compare rent and vacancy assumptions with market evidence and operating expenses with actual statements. Sellers should confirm payoff amounts and transaction costs.
Global use and local differences
The mathematical relationship can be used globally, but property taxes, transfer taxes, mortgage insurance, legal fees, stamp duties, agent commissions, depreciation rules and capital-gains treatment vary by country and location. Replace generic assumptions with figures applicable to the actual property.
Scenario analysis
Save a baseline and change one variable at a time—for example price, rent, vacancy, cap rate, mortgage rate or selling costs. This helps test whether a decision still works under less favorable conditions instead of relying on one optimistic estimate.
Common mistakes
- Using gross rent when a metric requires NOI.
- Including mortgage payments inside NOI.
- Assuming the currency selector performs FX conversion.
- Using tax or transaction-cost assumptions from another location without verification.
- Ignoring vacancy, maintenance, insurance, taxes or selling costs.

Frequently asked questions
Can I use this calculator outside the United States?
Yes for the core math, but local taxes, legal costs, financing rules and tax treatment must use figures applicable to the property.

Is the result a valuation, loan approval or tax calculation?
No. It is a planning estimate. Professionals may apply additional rules and property-specific evidence.
Methodology
Calconly stores each calculator’s inputs, outputs and formula separately from the editorial article. The engine can be tested independently while the page explains intent, assumptions, interpretation, common errors and related tools. Each URL targets a distinct real-estate decision or metric rather than publishing near-duplicate pages.
