BRRRR Investment Calculator

Quick answer

Calculate the scenario with the BRRRR Investment Calculator.

Quick answer. The BRRRR strategy attempts to recycle initial capital after purchasing, renovating, renting and refinancing. Net refinance proceeds can be lower than a simple loan-to-value multiplication after fees and retained loan balances. Property value, lender seasoning requirements and appraisal uncertainty are major risks. A $200,000 after-repair value at 75% assumed refinance LTV suggests $150,000 gross refinance principal. Check the applicable source records before treating this as anything beyond an illustrative calculation.

What does this calculator actually measure?

BRRRR Investment Calculator models buy, rehab, rent, refinance, repeat cash retained. The main decision is: How much capital remains in a BRRRR property? The value of a worksheet like this is that it keeps cost components, time periods and assumptions separate. Two cases may have the same headline percentage but produce different cash flows once fees, timing, benefit limits or starting balances are accounted for.

This calculator is especially useful when you already have written details about purchase price, rehab budget, and after repair value. Enter actual documents where available; if you are considering a proposed change, label hypothetical numbers as hypothetical and compare them with your current arrangement.

How to use this brrrr investment calculator

1. Confirm acquisition or current value, financing and verified property expenses.
2. Choose appropriate rent, vacancy and turnover assumptions.
3. Separate NOI, debt service, reserves and investor cash into distinct lines.
4. Run a downside scenario with higher expenses or lower occupancy.
5. Check local taxes, insurance and permitted rental-use rules independently.

Calculator inputs explained

• Purchase price: The supported market, insured or transaction value at the relevant date; these valuation types should not be substituted for one another.
• Rehab budget: Use the corresponding business metric from the same channel, cohort, currency and reporting period.
• After repair value: The supported market, insured or transaction value at the relevant date; these valuation types should not be substituted for one another.
• Hard-money fees: A monetary cost paid now or over time. Specify whether it is already included in another amount to avoid counting it twice.
• Refinance ltv: The value labeled “refinance LTV” in the underlying document or transaction. Enter its unit, timing and whether it is gross or net of another adjustment.
• Holding costs: A monetary cost paid now or over time. Specify whether it is already included in another amount to avoid counting it twice.

Keep all money in one currency and all rates and periods consistent. If you convert an annual amount into a monthly figure, show that conversion. When a required term is unknown, do not silently assume the most favorable outcome.

Formula and calculation method

The model for this specific worksheet is: cash_in=purchase+rehab+fees+carry; refi_amount=ARV*LTV; cash_left=all_in-refinance_proceeds_net_of_payoffs.

Normalize rental income and recurring costs to a consistent annual basis, separate operating expenses from debt service and reserves, then distinguish cash flow, net operating income, returns and tax treatment. The tool should retain full internal precision and round displayed currency amounts at the end of each legally or contractually appropriate computation. Show a complete breakdown for users who want to reproduce the result.

Worked example

A $200,000 after-repair value at 75% assumed refinance LTV suggests $150,000 gross refinance principal. This illustrates the buy, rehab, rent, refinance, repeat cash retained model using selected inputs, not a binding outcome. The relevant contractual or reporting record controls any additional conditions, ordering or rounding rules.

For a useful comparison, keep all other inputs fixed and change the specific parameter associated with appraisal and financing assumptions editable. That reveals whether the difference comes from the underlying base amount, timing, stated rate, cash charges or limits—not from several unexplained changes at once.

Understanding your results

• Cash left in deal: The intermediate or final result labeled “cash left in deal”, calculated using the entered scenario and the explicitly stated methodology.
• Refinance proceeds: The intermediate or final result labeled “refinance proceeds”, calculated using the entered scenario and the explicitly stated methodology.
• New debt service: The intermediate or final result labeled “new debt service”, calculated using the entered scenario and the explicitly stated methodology.
• Equity: The intermediate or final result labeled “equity”, calculated using the entered scenario and the explicitly stated methodology.

Review these figures together. Build conservative occupancy and repairs scenarios instead of assuming full rent collection. Compare a financed property with an unlevered one to see how debt affects cash flow without changing property-level NOI. A calculation is more reliable when you can point to the exact input and rule that explains every result.

What can materially change the answer?

The most important constraint for this tool: ARV and refinance terms are uncertain and require lender validation. Changes to these terms can alter the result even when the numerical inputs otherwise look similar. If the relevant record does not disclose a necessary restriction, treat the output as a partial scenario rather than a complete financial or coverage assessment.

Common errors to avoid:

• Using scheduled rent as though every month or night will be occupied.
• Subtracting principal-and-interest inside NOI and then using the result for cap rate.
• Failing to budget replacement reserves, transaction costs or cash tied up at purchase.

How reliable is this estimate?

Results are hypothetical property economics. They are not appraisals, guaranteed rents, underwriting approvals, zoning confirmations or individualized tax advice. The calculation does not retrieve live information automatically. The owner should use their own verified documents and check changing rules or annual limits before using the result in a consequential decision. CalculatorGeek's methodology should remain visible alongside the tool results.
