The Allocation by Value donut sits to the right of the Portfolio Value chart on the Analytics page, and it's the panel that answers "how is my stack split across the four metals?"
The ring breaks your holdings by dollar value; the number in the middle shows your total physical weight across every metal combined; the legend at the bottom lists each metal's value, weight, and percentage share.
This article covers what each piece of the chart represents, why allocation drifts even when you haven't bought or sold anything, and how the value-vs-weight mix in the visualization holds together.

What the donut shows
The ring of the donut is a value breakdown: each segment's arc length represents that metal's share of your current market value, computed at live spot.
So if your gold is worth $4,700 and your silver is worth $80, the gold segment takes 98.3% of the ring and silver takes 1.7%, regardless of how much each weighs.
Each metal has its own colour:
Gold: Gold/amber
Silver: Light grey
Platinum: Blue
Palladium: A darker tone
A portfolio holding only one metal renders as a single solid ring. A diversified portfolio shows distinct wedges, one per metal you hold.
The number in the center of the donut is a different question: it's your total weight across every metal you own, summed up in troy ounces (or grams, depending on your weight unit preference in Settings).
So if you hold 1 oz of gold and 30 oz of silver, the middle reads 31.000 oz, regardless of how much each metal is worth.
That mix — value on the ring, weight in the center, is intentional. The ring answers the dollar-allocation question; the center answers the physical-weight question. Together, they give you both lenses on the same stack.
Reading the legend
Underneath the donut, a small legend lists every metal you hold. Each row shows:
The metal name and its colour swatch.
The total dollar value of your holdings in that metal at current spot.
The total weight of that metal in your holdings.
The metal's percentage share of the portfolio (matching the ring segment).
The legend hides metals you don't own. If you only hold gold and silver, the legend shows only gold and silver — there's no zero-row clutter for platinum and palladium.
The numbers in the legend recalculate every time spot refreshes, so the percentage figures aren't static — they move with the market.
Why allocation shifts over time
This is the thing that catches people the first time. The allocation percentages can change even on days when you haven't recorded a single transaction. There are two reasons for that:
You bought or sold. Recording a new purchase adds to the metal you bought, shifting the split toward that metal. Recording a sale removes inventory from the metal you sold, shifting the split away from it.
Spot prices moved differently across metals. If gold went up 5% and silver went down 2% over a month, your gold's share of total value rises and your silver's share falls — even though you've added and removed nothing. The weight breakdown is unchanged; the value breakdown shifted because the prices moved.
Stated as a rule: the weight breakdown only changes when you buy or sell. The value breakdown changes every time spot refreshes for any metal you hold. The donut is the value breakdown, so don't be surprised when it drifts without any input from you.
This is part of why the page shows the weight total in the middle of the donut. The middle number anchors a stable physical reality — if you're holding 31 oz of metal at the start of the month and you didn't buy or sell, you're still holding 31 oz at the end of the month, regardless of what the dollar percentages did.
A note on value vs weight
Two ways to think about "how much" you hold, and both have their place:
Value is what your stack is worth right now in dollars. Useful for net worth questions, for comparing across metals at the same scale, and for thinking about exposure to price moves.
Weight is how much physical metal you have. Useful for storage planning, for thinking about long-term accumulation goals, and for the kind of question where dollars don't matter ("if I had to grab everything in one go, how heavy is it?").
The donut focuses on value because that's the answer to "what's my allocation," which is a dollar question.
But if you specifically want a weight breakdown — say, what percentage of your ounces are silver vs gold — that view lives in the Holdings by Form table further down the Analytics page, where the Weight column gives you a per-metal breakdown by tonnage rather than by dollars.
