A high return on a domain flip is meaningful only when the calculation includes the costs and identifies the completed transaction. A large resale price or automated appraisal does not establish return before a buyer pays and delivery completes.
Use a consistent definition and keep the asset scope clear. Website development is a separate expense and may create a different asset from the registration alone.
Define the calculation
For the worked example below, net profit is sale proceeds after selling charges, minus acquisition, holding and directly attributable research costs. ROI is that net profit divided by the costs committed before the sale, expressed as a percentage.
This denominator is explicitly acquisition plus holding plus research. Selling charges are deducted from proceeds once; they are not counted again in that denominator.
Use the same convention when comparing results and retain any other relevant costs separately.
A completed-deal example
Assume purely for illustration a domain bought for £80, with £20 holding costs and £10 research expense. It later sells for £350 and the assumed selling charge is 15%.
| Item | Illustrative amount |
|---|---|
| Acquisition, holding and research | £110 |
| Gross sale | £350 |
| Selling charge | £52.50 |
| Net sale proceeds | £297.50 |
| Net profit before other expenses or tax | £187.50 |
| ROI on the defined £110 commitment | Approximately 170.5% |
The fee rate and transaction are hypothetical. Sedo publishes service charges; use the actual terms of your chosen route in a real calculation.
Calculate the break-even sale
With the same assumed percentage charge and no extra minimum or fixed fees, break-even gross price is £110 divided by 0.85, approximately £129.42 rounded up to the next penny.
Additional expenses, a different charge basis or another renewal changes that threshold. The calculation identifies a required price, not evidence that a buyer will pay it.
Assess the buyer case before purchasing
Research useful wording, extension, relevant transactions and rights. Old links and a high authority score do not prove resale demand or inherited traffic.
Our appraisal workflow and resale evaluation guide support the acquisition ceiling.
Keep development and unsold names visible
Do not assume improving a website is mandatory or that its expense will be recovered in a domain-only sale. Record assets and costs according to what actually transfers.
A successful deal also does not establish portfolio profitability. Renewals and acquisition costs for names that remain unsold belong in the wider result.
Record the real outcome
Record the elapsed holding time as well as the percentage return, so comparisons retain the period during which money remained committed.
Retain invoices, selling charges, holding dates and completed delivery. Compare the realised figure with the assumptions recorded before buying.
Our ROI guide explains the wider ledger. High ROI is a result to calculate accurately, with no assurance that another name will produce the same sale or timeframe.
