The BRRRR Method Calculator is an essential tool for real estate investors who follow the Buy, Rehab, Rent, Refinance, Repeat strategy. BRRRR investing has become one of the most popular wealth-building approaches in real estate because it allows investors to recycle their capital across multiple properties rather than having large sums of money locked up in a single deal. This calculator analyzes every stage of the BRRRR process to determine whether a potential deal meets your investment criteria.
The core principle behind BRRRR is straightforward: you purchase a distressed property below market value, renovate it to increase its worth to the After Repair Value (ARV), place a tenant to generate rental income, then refinance based on the new appraised value. If executed correctly, the cash-out refinance returns most or all of your initial investment, leaving you with a cash-flowing rental property and little to no money left in the deal. You then repeat the process with the recovered capital.
What makes this calculator particularly valuable is its ability to project the cash-on-cash return based on how much capital actually remains tied up after refinancing. A deal where you pull out 100% of your invested capital and still generate positive cash flow technically produces an infinite cash-on-cash return. However, most realistic deals leave some money in, and this tool precisely quantifies that amount so you can compare BRRRR opportunities objectively.
The calculator factors in the refinance loan-to-value (LTV) ratio, which typically ranges from 70% to 80% of the ARV for investment properties. It computes your new mortgage payment using standard amortization formulas, then deducts that along with operating expenses from your gross rental income to determine net monthly cash flow. Understanding these numbers before you make an offer is crucial for avoiding deals that look good on paper but leave you over-leveraged or cash-flow negative after the refinance.
Whether you are a seasoned BRRRR investor evaluating your next acquisition or a beginner exploring this strategy for the first time, this calculator provides the financial clarity needed to make confident investment decisions. It accounts for purchase price, rehab budget, closing costs, holding period, and all ongoing expenses to give you a complete picture of your projected returns.
The BRRRR Method Calculator follows the actual deal mechanics step by step:
Step 1 — Total Investment: Total Cost = Purchase Price + Rehab Cost + Closing Costs. This represents all the capital you need to execute the deal before refinancing.
Step 2 — Refinance Amount: Refinance Loan = ARV × LTV%. For example, a $250,000 ARV at 75% LTV yields a $187,500 refinance loan. The bank lends based on the new appraised value, not your purchase price.
Step 3 — Cash Left in Deal: Cash Left = Total Cost − Refinance Amount. If the refinance covers your entire cost, you have $0 left in the deal (the ideal BRRRR outcome).
Step 4 — Mortgage Payment: Monthly Payment = Loan × r / (1 − (1+r)^(−n)), where r = annual rate / 12 and n = term × 12. This standard amortization formula calculates your principal and interest payment.
Step 5 — Cash Flow: Monthly Cash Flow = Rent − Operating Expenses − Mortgage. Annual Cash Flow = Monthly × 12.
Step 6 — Cash-on-Cash Return: CoC = Annual Cash Flow / Cash Left in Deal × 100. This metric tells you the annual percentage return on your actual out-of-pocket investment remaining after the refinance.
Step 7 — Equity: Equity = ARV − Refinance Loan Amount. This is the ownership stake you hold in the property above the debt.
A successful BRRRR deal typically shows cash left in deal below 20% of total cost — the less cash left, the better. If the calculator shows $0 or negative cash left, you have achieved a full capital recovery, meaning you can immediately redeploy those funds into the next property.
Cash-on-cash return above 12% is generally considered strong for BRRRR deals. Returns above 20% are exceptional. If your CoC is below 8%, the deal may not justify the effort and risk compared to more passive investment options.
Monthly cash flow should be positive after all expenses including the refinanced mortgage. A common rule of thumb is at least $200/month per unit in net cash flow. If cash flow is negative, the property will drain your reserves each month.
The equity position represents your built-in wealth. Even deals with modest cash flow can be attractive if they create significant equity through the value-add renovation process.

This deal achieves full capital recovery. The $165,000 refinance exceeds the $159,000 total cost, leaving $0 in the deal with $206.91/month positive cash flow and $55,000 in equity. The investor can recycle all their capital into the next BRRRR deal.

At a conservative 70% LTV, the investor has $35,000 left in the deal but earns a 10.16% cash-on-cash return with $296/month cash flow. The $84,000 equity position provides a strong safety margin.
BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. It is an investment strategy where you purchase undervalued properties, renovate them to increase value, rent them out for income, then refinance based on the new higher value to pull out your invested capital. The recovered funds are then used to acquire the next property, allowing you to scale your portfolio without needing fresh capital for each deal.
Most lenders offer 70% to 80% LTV on investment property refinances. Conventional lenders typically cap at 75% LTV, while some portfolio lenders or credit unions may go up to 80%. Higher LTV means more capital recovery but also higher monthly payments. The LTV is based on the appraised after-repair value, not your purchase price, which is why buying below market value is essential for BRRRR success.
Most conventional lenders require a 6-month seasoning period before allowing a cash-out refinance based on the new appraised value. Some lenders have 12-month seasoning requirements. During this period, you typically hold the property with hard money or private financing. A few portfolio lenders and DSCR lenders offer no-seasoning refinance options, though often at slightly higher interest rates.
A good cash-on-cash return for BRRRR deals is 12% or higher. Many experienced BRRRR investors target 15-25% CoC. If you achieve full capital recovery (zero cash left in the deal), the CoC is technically infinite, which is the ideal BRRRR outcome. Returns below 8% may not adequately compensate for the risk and effort involved in a value-add renovation project.
A low appraisal is one of the biggest risks in BRRRR investing. If the ARV appraises lower than projected, you will receive a smaller refinance loan, leaving more cash stuck in the deal. To mitigate this risk, use conservative ARV estimates based on comparable sales, get a pre-rehab appraisal or broker price opinion, and focus on renovations that add the most appraised value per dollar spent.
Absolutely. Most investors include 5-10% of gross rent for vacancy reserves in their operating expenses. BRRRR properties are rental investments, and vacancies are inevitable. Include vacancy, maintenance (5-10%), capital expenditure reserves (5-8%), and property management (8-12% if applicable) in your expense calculations for an accurate cash flow projection.
Yes, hard money loans are the most common financing method for the initial BRRRR purchase and rehab. These short-term loans typically charge 10-14% interest with 1-3 points and fund 70-90% of the purchase plus rehab costs. The key is that your all-in cost (purchase + rehab + hard money costs) must be less than your refinance amount for the BRRRR to work. Factor hard money interest into your holding costs calculation.
The 70% rule states that you should pay no more than 70% of the ARV minus repair costs. Formula: Max Purchase = ARV × 0.70 − Rehab Cost. For example, if ARV is $200,000 and rehab is $30,000, max purchase = $200,000 × 0.70 − $30,000 = $110,000. This rule ensures you have enough margin to recover your capital on a 75% LTV refinance while accounting for closing and holding costs.
ARV is estimated using comparable sales analysis. Look at recently sold properties (within 3-6 months) in the same neighborhood that are similar in size, age, and condition to what your property will be after renovation. Use at least 3-5 comps. Online tools like Zillow and Redfin provide initial estimates, but for accuracy, consult a local real estate agent or appraiser who understands the specific market. Conservative ARV estimates protect against refinancing shortfalls.
The primary risks include: rehab cost overruns that exceed budget and reduce returns, low appraisals that prevent full capital recovery, extended holding periods that increase carrying costs on hard money loans, rental income falling short of projections, and interest rate increases between purchase and refinance that raise your permanent mortgage payment. Mitigate these by using conservative projections, maintaining cash reserves, and building contractor relationships for reliable rehab estimates.
