What that latte is really costing you, in GBP.
Type any price. CostMe shows what it could be worth in 30 years if you invested it instead, using the S&P 500, priced in pounds. One calm number, right before you decide.
Past performance does not predict future results. CostMe shows this for opportunity-cost math, not investment advice.

Through an ISA, your gains stay yours.
Money that grows inside a Stocks and Shares ISA is not taxed on the way out. So the second number you see here, what the purchase could have become, is closer to what you would actually keep. That is context, not tax advice.
CostMe is not a ISA and does not move your money. It is the quiet second number you see before a purchase. The math is yours to act on.
The math runs on VUSA.L, the index Britons already recognize.
A local benchmark, not a U.S. one
CostMe does the opportunity-cost math against VUSA.L at 13% a year, so the second number is framed in the currency and market you live in. Long-run average: about 13% per year, measured in GBP.
Lifted by years of U.S.-dollar strength against the pound. A stronger pound would pull this back down.
Built for the purchases you actually make
The meal-deal habit, the streaming stack, the next-day delivery you tapped without thinking. Small UK purchases, repeated, are where the real opportunity cost hides.
CostMe meets you in that one second before the tap, with no shame and no broken-streak guilt. Just the number, and your decision.
