The Vanguard FTSE Global All Cap Acc and the Vanguard FTSE Global All Cap Inc are the same fund. Same £10.0bn in assets, same 0.23% annual fee (OCF), same 9,000-odd companies underneath. But their unit prices look nothing alike — and that confuses a lot of investors into drawing conclusions the numbers don’t actually support.
What the unit price is — and isn’t
Every fund has a net asset value: take everything the fund owns, subtract any costs, divide by the number of units in existence, and you get the price per unit. That calculation is mechanical. It tells you what a single unit is worth at close of business today. It does not tell you whether the fund is cheap, expensive, well-run, or good value. It doesn’t even tell you much about performance unless you track it across two points in time — and even then, only for one of these two classes.
Here’s the catch with the income-paying share class (the Inc share class). Every time a dividend lands — from Microsoft, from Shell, from a Japanese manufacturer — the fund pays that cash out to you. The unit price then falls by the amount of the distribution. Over years, this means the Inc class price drifts structurally lower than it would have been if dividends had been retained.
The accumulation class (the Acc share class) does the opposite. Every dividend stays inside the fund, is reinvested, and the unit price rises to reflect that. So the Acc class unit price, all else equal, will always look higher than the Inc class unit price — and the gap widens over time.
Neither class is performing better. They own identical assets. The unit price divergence is a feature of the accounting, not a signal about returns.
Why this misleads — and what to look at instead
The instinct to treat a lower unit price as a bargain is understandable. It’s how equities work — a £5 share feels different from a £500 share. But funds aren’t priced that way. A unit in a £10 fund and a unit in a £100 fund give you proportionally identical exposure to the same assets. The number itself carries no signal.
This matters most when investors compare the two Vanguard classes side by side and conclude the Inc class is cheaper or has underperformed. It hasn’t. It has distributed cash you’d otherwise see in the price. If you’re holding inside a stocks-and-shares ISA and automatically reinvesting dividends, the total-return outcome of both classes is very similar. The difference becomes meaningful in a taxable account, where the timing and nature of distributions can affect your tax position — but that’s a personal-circumstance question, not a fund-quality question.
The metrics that actually matter for evaluating a global tracker like this one are three: the annual fee (0.23% here, which is among the lowest in this category), tracking difference — how closely the fund follows the FTSE Global All Cap index net of all costs — and the breadth of coverage, which at over 9,000 companies is as wide as any retail investor is likely to need.
What to watch
First, keep an eye on the OCF over time. Vanguard has a history of passing scale savings on to investors as the fund grows — at £10.0bn, this is now one of the largest single index funds in the UK market, and any fee reduction would compound meaningfully over a decade. Second, if you hold the income-paying class, track total return rather than unit price — your platform should show this, and it’s the only honest comparison to the accumulation class. Third, and most practically: if you’re ever tempted to switch from Inc to Acc because the price looks lower on one, don’t. The decision should rest on whether you want cash distributions or compounding, not on which number looks bigger on a screen. That’s the one that matters most.
