Free Rental Property Calculators for Landlords and Investors
Each calculator here shows its formula and a worked example alongside the tool itself, so you can see exactly how a result was reached — not just the final number. Rent-focused calculators (affordability, increase, prorated rent) suit landlords and tenants; the investment calculators (cap rate, cash-on-cash return, vacancy loss) suit small real estate investors comparing deals.
Estimates for Planning, Not Financial Advice
These are planning estimates based on the numbers you enter — not financial, tax, or legal advice, and not a substitute for your own records or a qualified professional where it matters. For documenting what actually happens, pair a calculator with a record-keeping tool like the Rent Receipt Generator or Tenant Ledger.
