Who We Are
Free tools built for independent landlords who manage their own rental properties.
LandlordCalcs is a free toolkit for independent landlords and rental property investors. It covers the quick-math calculations that come up constantly in day-to-day property management — prorating rent, screening tenants by income, evaluating investment returns, calculating late fees, and totaling move-in costs.
Every calculator is designed around real landlord scenarios. Results are instant, work on any device, and require no account or subscription. The site is supported by advertising so all tools remain free.
LandlordCalcs is built for the independent landlord — the person who owns one unit or a small portfolio and handles their own property management. These are the landlords who don't have a property management software subscription or an accountant on speed dial, but still need accurate numbers fast when a tenant calls or an investment opportunity comes up.
We also offer downloadable spreadsheet templates in our Etsy shop for landlords who want to track rent rolls, security deposits, expenses, and property performance across multiple units in one place.
LandlordCalcs calculators use standard formulas and are designed to produce accurate estimates for planning and reference purposes. However, landlord-tenant law varies significantly by state and city. Security deposit limits, late fee caps, grace period requirements, and lease break rules all differ by jurisdiction — and they change over time.
Nothing on LandlordCalcs constitutes legal or financial advice. For questions about your specific rights and obligations as a landlord, consult a local real estate attorney or your state's landlord-tenant authority. See our full Disclaimer for details.
