Calculation method
Calculation method
Annual base rent = area × annual rate per area unit; term cost = (base rent + annual other charges) × years.
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
2,000 area units at 30 annually plus 5,000 other annual charges costs 65,000 annually.
