CapEx Calculator: Real Estate Sinking Funds & Corporate PP&E Modeling
Capital Expenditures (CapEx) represent investments in structural, long-lived assets that provide economic utility beyond the current tax year. In rental real estate, CapEx budgeting protects landlords from devastating surprise expenses like roof replacements ($10,000–$18,000), HVAC systems ($6,000–$12,000), and water heaters ($1,500–$3,000).
CapEx vs. OpEx: Critical Distinction
Operating Expenses (OpEx) are recurring day-to-day costs (utilities, property management, minor repairs) that are 100% tax-deductible in the year incurred. CapEx must be capitalized onto the balance sheet and depreciated across statutory IRS MACRS schedules (27.5 years for residential rental properties).
