About FreeREICalc
FreeREICalc is a free set of real estate calculators and guides designed to help you make confident decisions faster—whether you’re buying your first home, analyzing a rental property, or underwriting deals.
Why it exists
Real estate decisions are often made with incomplete math, unclear assumptions, and spreadsheets that don’t match reality. FreeREICalc was built to provide:
- Practical assumptions (maintenance, vacancy, reserves) so you don’t overestimate returns.
- Clear explanations for what each number means and how to interpret the output.
- Mobile-first UX so you can run the numbers in seconds, anywhere.

Who built it
FreeREICalc was built by KRG Investment, a business operator and real estate enthusiast with a background in leadership, analytics, and customer-facing work. The goal is simple: ship calculators that are easy to use, transparent about assumptions, and helpful enough that you’d share them with a friend.
