Built by Peter · Independent Developer & Underwriting Tools
Free, professional commercial real estate calculation tools running 100% locally in your browser.
I built crecalculators.com because checking a commercial real estate deal shouldn't require an unwieldy spreadsheet or a paid subscription service. Every calculator on this site runs entirely in your browser — zero sign-up, zero accounts, and zero financial data sent to remote servers.
Editorial & Mathematical Verification Standards
- Client-side computation: all formulas execute in real-time JavaScript without remote API latency or data tracking.
- Documented formulas: every metric shows its exact mathematical formula, definitions, and worked examples.
- Market benchmarks: typical underwriting thresholds (such as 1.25x DSCR or 85% BER) are clearly labeled as standard guidelines, not guaranteed lender commitments.
This site is an independent calculation tool, not a brokerage, lender, or financial advisory firm. Nothing on this website constitutes tax, legal, or investment advice.
Frequently Asked Questions About Commercial Real Estate Analysis
Clear answers on calculation accuracy, privacy, financial metrics, and export workflows.
How do these calculators protect the confidentiality of my deals?
Every calculator on crecalculators.com executes 100% client-side inside your browser. No purchase prices, rental rolls, operating expenses, or mortgage debt parameters are ever transmitted to a server or stored in a database. Your underwriting figures remain strictly confidential on your personal device.
What is the difference between Cap Rate and Cash-on-Cash Return?
Cap Rate (Capitalization Rate = NOI ÷ Purchase Price) measures the unleveraged operational yield of the property as if acquired entirely for cash, making it ideal for comparing different properties and markets. Cash-on-Cash Return measures your leveraged first-year cash return on the actual out-of-pocket equity invested after paying annual mortgage debt service.
What minimum DSCR do commercial mortgage lenders look for?
Commercial banks and agency lenders (Fannie Mae, Freddie Mac) typically require a minimum Debt Service Coverage Ratio (DSCR) of 1.20x to 1.25x. This buffer ensures the property's Net Operating Income (NOI) covers annual loan payments with a 20% to 25% safety cushion to absorb tenant turnover or unexpected maintenance expenses.
How does the Break-Even Ratio (BER) differ from Break-Even Occupancy (BEO)?
The Break-Even Ratio (BER) measures what percentage of Effective Gross Income (EGI) is consumed by operating expenses and debt service: BER = (OpEx + ADS) ÷ EGI. Break-Even Occupancy (BEO) calculates the physical occupancy percentage needed against Gross Potential Income (GPI) to generate enough revenue to pay all obligations: BEO = (OpEx + ADS) ÷ GPI.
Can I export my underwriting scenarios to share with lenders or partners?
Yes. Our Deal Analyzer and individual calculators support one-click CSV export (strictly RFC 4180 compliant) and instant browser link sharing via URL hash encoding, making it easy to review underwriting scenarios with partners, lenders, or brokers without creating an account.
