What is a fix and flip loan calculator?

A fix and flip loan calculator models purchase price, rehab budget, hard money LTC/leverage, interest-only carry during hold, and sale costs against ARV to estimate net profit and cash-on-cash return before you apply for bridge financing.

What is a good profit on a fix and flip?

Experienced sponsors often target $20K–$40K net on sub-$300K ARV deals in Midwest and Southeast markets after 8% sale costs and hard money carry. Thin spreads under $12K may warrant a BRRRR hold instead.

What costs does this calculator include?

Purchase, rehab, estimated purchase closing costs of 2%, interest-only hard money carry, entered insurance/utilities during hold, and sale costs as a percent of ARV. Points, property taxes, draw fees and costs not entered are excluded. ROI uses your own cash paid for the project and carry through sale.

How does LTC affect flip profit?

Higher loan-to-cost reduces cash in but increases interest carry. At 11% IO, each extra month on a $200K balance costs roughly $1,833 — model hold time honestly.

When should I pivot from flip to BRRRR?

When net flip profit falls below your minimum spread but stabilized rent supports DSCR at 70%–75% LTV. Use our DSCR calculator on the projected rent after rehab.

Fix and Flip Loan Calculator — Profit & LTC Estimator

This fix and flip loan calculator estimates net profit on a residential flip: purchase + rehab + hard money carry + sale costs against your projected after-repair value (ARV). Model LTC (loan-to-cost) to see how leverage changes cash in versus interest carry. Pair results with our DSCR calculator if the deal pivots to a hold. Full walkthrough: how to use the fix and flip calculator.

How to use this calculator — ARV first, LTC scenarios, sale-cost defaults, and a stress-tested Indianapolis walkthrough.

How to use this fix and flip loan calculator

Enter purchase price, rehab budget, ARV, LTC %, interest rate, and hold months. The calculator outputs estimated hard money loan amount, project equity gap, total own cash through sale, and net profit after the included costs.

ARV first — use three conservative comps; overstated ARV breaks every downstream line
LTC sensitivity — run 85%, 90%, and 100% requests; the ARV and loan-size limits may reduce the modeled proceeds
Hold time — add 30–60 days buffer for permits and DOM in your market
Sale costs — 7%–9% of ARV is typical (agent, title, transfer, staging)
Exit compare — if net profit < $15K, run the same inputs on the DSCR calculator for BRRRR hold math

Fix and flip loan calculator formula

Modeled loan = the lowest of requested LTC × (purchase + rehab), 75% of ARV, and $10 million.

Above $2.5M, leverage requires an individual quote; the selected LTC is only an illustration. That threshold is separate from the maximum loan size. All loans remain subject to underwriting. Monthly interest ≈ modeled loan × annual rate ÷ 12. Interest assumes the full modeled balance is outstanding throughout the hold.

How LTC and hard money carry affect flip profit

Loan-to-cost (LTC) determines how much cash you bring versus how much interest you pay during hold. At 11% interest-only, each extra month on a $200K balance costs roughly $1,833 — a 7-month hold vs 5-month plan erases $3,666 of net profit before sale costs.

Qualified fix-and-flip loans up to $2.5M may reach 100% LTC, subject to the 75% ARV limit. Larger loans have leverage quoted individually. See Fayetteville 100% financing case study.

When to pivot from flip to BRRRR

When net flip profit falls below your minimum spread but stabilized rent supports DSCR at 70%–75% LTV, model the hold exit with our DSCR calculator. Thin flip spreads under $12K often warrant BRRRR on Indiana and Illinois duplex stock.

Fix and flip profit formula

Net profit = ARV − purchase − rehab − estimated purchase closing costs − interest − entered property carry − sale costs.

All-in cost — purchase, rehab, estimated purchase closing costs, interest, entered carry and sale costs
Own cash paid through sale — purchase + rehab − modeled loan + purchase closing costs + hold payments
ROI on cash — net profit divided by own cash paid through sale, including carry
Carry — monthly interest plus the entered insurance and utilities; taxes and other unentered costs are excluded
Sale costs — often 7%–9% of ARV (agent, title, transfer, staging)
