About

Cash Flow Numbers provides free real estate investment calculators. All calculations run on your device in your browser. We do not receive the numbers you enter.

The tools are built to be simple, fast and transparent about their formulas.

Alex Carter is a finance writer and calculator developer. The goal behind every tool on this site: give you the exact number a paid professional would produce — instantly, privately, and free.

Cash Flow Numbers is one of several focused calculator sites built by the same team. The others cover adjacent topics:

• Main Street Numbers — business financing, SBA loans, MCA, and self-employed tax tools
• Trucker Numbers — IFTA, load profit, per diem, and owner-operator calculators
• Recovery Numbers — personal injury, workers' comp, debt relief, and settlement calculators
