How to use this calculator

  3. Review the calculator-specific boundary before interpreting the result.

Calculation method

Calculation method

Year n rent = initial annual rent × (1 + annual increase)^n−1; term total is the sum of annual rents.

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

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 change applies once between lease years. Fixed steps, index floors, caps, reviews, and partial years require separate contract modeling.
