ARV Calculator for Real Estate: Free Tool & Complete Guide

An ARV calculator for real estate is the most important tool in any investor's toolkit. Whether you're analyzing your first deal or your hundredth, understanding After Repair Value is essential for profitable investing.

What is an ARV Calculator?

An ARV calculator is a tool that estimates a property's market value after renovations are complete. "ARV" stands for After Repair Value—what buyers will pay for your property once it's fully renovated.

For real estate investors, the ARV calculator determines:

  • Maximum purchase price (using the 70% rule)
  • Potential profit margins
  • Whether a deal is worth pursuing

How to Use an ARV Calculator for Real Estate

Step 1: Gather Property Information

Before using your ARV calculator, collect the property address, square footage, bedroom/bathroom count, lot size, and current condition assessment.

Step 2: Find Comparable Sales

The best ARV calculators for real estate automatically find comps. PropLab's AI searches for sales within 0.5-1 mile radius, properties sold in the last 6 months, similar size properties, and same property type.

Step 3: Make Adjustments

Your ARV calculator should adjust comps for differences in square footage, bedrooms, bathrooms, garage, pool, and condition.

Step 4: Calculate Your ARV

The ARV calculator averages adjusted comp values, weighted by similarity and recency. PropLab provides Conservative ARV (low), Likely ARV (mid), and Optimistic ARV (high).

The 70% Rule and Your ARV Calculator

Once you have your ARV, apply the 70% Rule to determine your maximum offer:

Maximum Offer = (ARV × 70%) - Repair Costs

Example:

  • ARV from calculator: $400,000
  • Estimated repairs: $50,000
  • Maximum offer: ($400,000 × 0.70) - $50,000 = $230,000
