Maximum Allowable Offer Calculator
In real estate investing, knowing how much to offer on a property is just as important as finding the deal itself. Offer too much, and your profits vanish. Offer too little, and the deal slips away. That’s why seasoned investors rely on a powerful formula called the Maximum Allowable Offer (MAO).
The Maximum Allowable Offer Calculator is a simple yet essential tool that calculates the most you can pay for a property while still achieving your desired profit margin after accounting for repairs and other expenses.
Whether you’re a house flipper, wholesaler, or buy-and-hold investor, this calculator is your safeguard against overpaying.
Formula
The Maximum Allowable Offer (MAO) formula is:
MAO = ARV − Repair Costs − Closing Costs − Desired Profit
Where:
- ARV (After Repair Value): Estimated resale value after renovations
- Repair Costs: Total estimated cost to rehab the property
- Closing & Holding Costs: Additional transactional or carrying costs
- Desired Profit: Your target profit amount from the deal
Some investors simplify the formula as:
MAO = (ARV × 70%) − Repair Costs
This version assumes a 30% margin for profit and other costs. The calculator above is more flexible and accurate for custom scenarios.
How to Use the Maximum Allowable Offer Calculator
- Enter ARV (After Repair Value):
This is the projected resale price after renovations. Use comps and market research. - Enter Repair Costs:
Estimate all expenses needed to bring the property to resale condition. - Enter Closing & Holding Costs:
Includes title fees, utilities, insurance, property taxes, agent commissions, etc. - Enter Desired Profit Margin (%):
Typically ranges from 10%–30% depending on your risk and market. - Click “Calculate”:
The calculator displays your MAO—the absolute ceiling on your offer.
Example Calculation
Let’s say you’re evaluating a distressed property:
- ARV = $250,000
- Repair Costs = $40,000
- Closing Costs = $15,000
- Desired Profit Margin = 20%
Step 1: Calculate profit = $250,000 × 20% = $50,000
Step 2: MAO = $250,000 − $40,000 − $15,000 − $50,000 = $145,000
So, your maximum allowable offer on this deal is $145,000.
