Worked UK example
From asking price to real projected profit
A car costs £5,100. Repairs are estimated at £340 and collection, MOT, fuel, checks and advertising add £222. At a realistic £6,800 sale price, the deal looks like this:
| Calculation | Formula | Result |
|---|---|---|
| Total cost | £5,100 + £340 + £222 | £5,662 |
| Projected net profit | £6,800 - £5,662 | £1,138 |
| Projected ROI | £1,138 ÷ £5,662 × 100 | 20.1% |
| Sale margin | £1,138 ÷ £6,800 × 100 | 16.7% |
| Break-even sale price | Total money committed | £5,662 |
This is a projection, not a valuation or guarantee. Recheck the sale comparison, inspect the vehicle and add a contingency before committing.
How to Use This Calculator
Enter the buy price
This is what you paid or plan to pay for the vehicle. If buying at auction, use the hammer price - you will add the buyer premium in other costs.
Add repairs and parts
Include every mechanical and cosmetic repair. Be honest - underestimating here is the most common reason flippers overstate their profit.
Add other costs
MOT test, valeting, fuel, advertising, platform fees, insurance allocation, road tax, HPI check. Every pound spent between purchase and sale counts.
Enter your expected sale price
Use comparable listings on Facebook Marketplace and AutoTrader to set a realistic figure - not your optimistic ceiling, but what similar cars are actually selling for.
What the Results Mean
Net Profit
Your sale price minus every cost. This is the real money in your pocket after the flip is complete.
ROI %
Return on investment. Divide projected net profit by total cost, then multiply by 100. Compare it with risk and expected time held.
Break-even Price
The minimum you can sell for without losing money. Know this before every negotiation.
Margin Above Break-even
How much headroom you have between your break-even and your expected sale price. This is your negotiating buffer.
Frequently Asked Questions
How do I calculate profit when flipping cars in the UK?
Subtract your total costs from your sale price. Total costs include the purchase price plus every additional expense - repairs, parts, MOT, fuel, advertising, and valeting. The result is your net profit. Divide net profit by total cost and multiply by 100 to get your ROI percentage.
What is a good profit margin for flipping cars in the UK?
There is no universal target because preparation risk, capital, time held and buyer demand vary by vehicle. Compare projected profit with total cost, likely holding time and a realistic repair contingency. A higher headline margin is not safer if the sale value or cost estimate is weak.
What is break-even price when flipping a car?
Break-even price is the minimum amount you need to sell a car for to recover every pound you have spent on it - purchase price plus all costs. Every penny above break-even is profit. Knowing this number before you negotiate a sale prevents you from accepting an offer you cannot afford to take.
What costs should I include when calculating car flip profit?
Include the purchase price, auction buyer premium if applicable, all repairs and parts, MOT test, fuel for collection and test drives, valeting, advertising and platform fees, insurance allocation, road tax, and any other expense directly related to the vehicle. Forgetting these smaller costs is the most common reason flippers overestimate their profit.
How accurate is a car flipping profit calculator?
A calculator is only as accurate as the numbers you put in. The most common mistake is underestimating costs - particularly the smaller ones like fuel, HPI checks, and platform fees. If you are tracking costs properly on every vehicle, the calculator gives you an accurate result in real time.
Can I use this calculator before buying a car to flip?
Yes - this is exactly what it is designed for. Enter the asking price as your buy price, estimate your prep costs, and enter a realistic target sell price based on comparable listings. The calculator tells you instantly whether the deal is worth pursuing and what margin you have to negotiate with.
