- Use the field labels to preserve each page's specific investment, transaction, lease, development, or lodging convention.
- Review the calculator-specific boundary before interpreting the result.
Calculation method
Calculation method
Base cap rate = NOI ÷ value; downside lowers NOI and raises value; upside raises NOI and lowers value by entered percentages.
Entered fixed decimals use exact rational arithmetic except the explicitly approximate IRR root. Money rounds only for display and supported nonzero amounts remain visible.
Worked example
Worked example
80,000 NOI on 1,000,000 value has an 8% base cap rate; 10% paired changes show downside and upside cases.
Base cap rate = NOI ÷ value; downside lowers NOI and raises value; upside raises NOI and lowers value by entered percentages.
Supported inputs
Precision and limits
Visible input limits
Amounts accept up to 30 digits and 12 decimal places and are capped at 1e12 per input. Whole-number periods are capped at the page's stated range; rates are capped at 1000%.
International scope
No currency, tax regime, lease law, lender threshold, local market feed, appraisal, or jurisdiction-specific charge is assumed.
Decision boundary
Results are visitor-entered arithmetic scenarios, not appraisals, forecasts, loan approvals, legal or tax determinations, or investment recommendations.
Calculator-specific assumptions
The paired cases are mechanical sensitivities, not forecasts or probabilities. This page deliberately exposes its scenario convention.
