Domain investment calculator

Free domain investment calculator: total holding cost, profit after commission, break-even sale price and expected value based on your chance of selling each year.

Before you buy a domain as an investment, run the numbers. Renewals add up quietly, and most names don't sell every year. This calculator shows your total cost, your profit if you sell, and a realistic "expected" result that accounts for the chance of not selling.

Domain investment calculator

Many investors see only a small percentage of their portfolio sell each year, so a low yearly chance (often 1% to 5%) is realistic for most names. Adjust it to match your own results.

How to read the results

  • Total cost if it never sells: what you'll pay in purchase plus renewals over the holding period.
  • Profit if it sells in year 1 or at the end: what you'd keep after commission and renewals.
  • Expected result: the average outcome across all the possibilities, using your chance of selling. If this is negative, the name probably isn't worth holding at these numbers.
  • Break-even sale price: the lowest sale that covers all costs if it sells at the end.

Making the numbers work

  1. Keep renewals low. High-renewal endings need much higher sale prices.
  2. Be honest about the sale price. Use real comparable sales from NameBio, not appraisal tools alone.
  3. Price to sell. A fair buy-now price raises your chance of selling each year.
  4. Drop names that don't add up. Letting weak names expire is often the best financial decision.

Questions

What is a good sell-through rate for domains?

Many investors report selling only a small percentage of their portfolio each year, often in the low single digits. Use your own history if you have it.
