BRRRR Formulas is a free, no-signup calculator built specifically for real estate investors using the Buy-Rehab-Rent-Refinance-Repeat strategy. Our mission: give every investor fast, accurate BRRRR math without paywalls, logins, or upsells.

Why We Built This

The BRRRR strategy has exploded in popularity, but most online calculators either oversimplify the math (ignoring holding costs, refinance closing costs, or cash-on-cash return) or hide the results behind email capture forms. We built the BRRRR calculator because investors need to quickly model deals end-to-end: total investment, refinance proceeds, capital left in the deal, monthly cash flow, and infinite return potential.

Our Principles

  • Always free: No paywalls, no premium tiers, no "unlock full results" upsells
  • No signup required: Use the calculator anonymously, no email capture
  • Accurate math: Real amortization formulas, real DSCR logic, real BRRRR calculations
  • Privacy first: We don't collect personal data from the calculator
  • Honest disclaimers: Every page makes clear these are estimates, not professional advice
  • No lead selling: We don't sell your information to lenders or brokers

Who Uses BRRRR Formulas

  • Real estate investors analyzing BRRRR deals before purchase
  • Investors modeling refinance scenarios after rehab
  • Lenders evaluating BRRRR refinance qualifications
  • Real estate coaches and educators teaching the BRRRR strategy
