Comparison

VUAG vs CSP1

Vanguard S&P 500 UCITS ETF Acc (VUAG) and iShares Core S&P 500 UCITS ETF (CSP1): what each one is, what it costs, how it has done before and after inflation, how far it fell, and how much of what they hold is the same. Nothing here says which one to choose.

Growth of £10,000 over 12 months

to · after fund charges, before inflation

From 14/11/2025 to 13/11/2026, £10,000 became £11,197 in VUAG, £11,200 in CSP1, after fund charges and before inflation.
  • VUAG£11,197+12.0%
  • CSP1£11,200+12.0%

The start is the first date every fund has a price. Weekly closes of the price as traded: income a fund pays out is not counted, so a distributing fund’s line understates its total return (see “Measured as” below). Where we hold no close of our own, the week’s close is from the weekly price history for the listing.
