After Repair Value (ARV) Calculator

What is ARV and Why it Matters

ARV, or After Repair Value, is the projected market value of a property after renovations. Investors use it to estimate potential profits, decide how much to invest, and plan renovation budgets. Understanding ARV ensures you make informed decisions, avoid overpaying, and confidently pursue profitable deals.

After Repair Value Calculator

Estimate what a property will be worth once the work is done, the highest price you should pay for it, and what you stand to make.

1 · After Repair Value

Choose how you want to estimate the finished value.

Current value + renovations Comparable price per area

Property value today

As-is market value before any work.

Value added by renovations

Appraised lift, not what you spend.

2 · Repair Budget

What the rehab will actually cost you.

Total cost of renovation

Materials, labor, permits — everything you pay out.

Estimate by square footage Calculate the budget from a per-ft² rate instead of a lump sum.

3 · Your Offer Rule

The share of ARV you are willing to spend, all-in.

Maximum share of ARV 70%

The classic 70% Rule: never pay more than 70% of the after-repair value, minus the repair budget. Lower is more conservative.

4 · Purchase Price

Used to work out your return. Defaults to the maximum bid.

Price you will actually pay

Enter a purchase price greater than zero.

Use the maximum bid price Turn this off to model a different offer.

Results are based on the figures you enter and do not account for closing costs, financing and holding costs, agent commissions, or taxes, each of which reduces your actual return.
