Chocolate truffle cost: tempering loss and boxes

The cost of a truffle or bonbon comes from four things: the chocolate you really use (what ends up on the piece plus what you lose when tempering), the filling, the paper cup and your time. All of that is spread over the pieces that come out right, not over the ones you made. Then you add the box, which with chocolates often costs more than several pieces put together. The most common mistake is costing from the chocolate in the recipe and forgetting what stays in the bowl, on the spatula and in the pieces that do not make the box.

How much chocolate each piece really uses

The chocolate you buy ends up in three places:

1. On the pieces. For truffles, weigh ten centres before dipping and again after; for moulded bonbons, weigh ten finished pieces and ten portions of filling. The difference divided by ten is the chocolate per piece.
2. Recovered. What you scrape clean from the bowl and the marble and keep for the next batch. It is not lost: it goes back in.
3. Lost. What clings to the spatula, the fork and the moulds, what gets mixed with filling or water, what gets thrown out.

To find out how much you lose, weigh the chocolate before melting and weigh what you recover at the end:

chocolate used = chocolate melted − chocolate recovered

loss = chocolate used − chocolate on the pieces

That number is yours. It depends on your technique, your tools, batch size and how warm your kitchen is. Measure it over several batches. Dipping usually needs a deep bowl of melted chocolate, so you melt far more than ends up on the truffles; what matters is how much of it comes back.

Rework costs too

Recovered chocolate is not free. Retempering takes time, and if filling, moisture or crumbs got into the bowl, that chocolate is no good for coating any more and becomes waste. If you retemper a lot every batch, the cost shows up in hours, not in couverture.

Filling, cups and rejects

Filling is costed like any recipe: ganache, praline, caramel, fruit. Weigh what goes into each piece and count what stays in the piping bag.

Each truffle sits in a paper cup. A few cents per piece becomes more than a third of a dollar in a box of twelve.

Pieces that crack, bloom or come out lopsided do not go in the box. Count them in every batch and divide the cost by the ones that are sold.

The box

The box goes on afterwards, per box rather than per piece: box, insert, ribbon, sticker. With chocolates the presentation sells, which is why the box often costs more than two or three truffles. The guide on how to cost packaging and labels shows how to get the unit cost of each part.

Worked example: a box of 12 dark chocolate truffles

You make hand-rolled ganache truffles, dipped in tempered dark couverture and rolled in cocoa. You roll 80 in a batch. Couverture costs you $15.00 per kg.

Ganache. 0.6 kg of chocolate ($9.00), 0.4 litres of cream ($2.40) and 30 g of butter ($0.30): $11.70.

Coating. Weighing ten centres before and after dipping tells you each truffle carries 5 g of chocolate: 80 × 5 g = 0.4 kg on the truffles. You melted 0.8 kg to have enough depth to dip and recovered 0.33 kg clean at the end.

• Chocolate used: 0.8 − 0.33 = 0.47 kg
• Loss: 0.47 − 0.4 = 0.07 kg
• Cost of coating chocolate used: 0.47 × 15.00 = $7.05

Cocoa for rolling. 50 g: $1.00.

Pieces sold. Four of the 80 came out misshapen: 76 go into boxes.

Paper cup: $0.03 per truffle.

Your time. Making the ganache, rolling, dipping and boxing takes 3 hours. You value your hour at $18: $54 ÷ 76 = $0.71 per truffle.

Cost per truffle: 0.26 + 0.03 + 0.71 = $1.00.

Cost per box of 12:

• Truffles: 12 × 1.00 = $12.00
• Box with insert: $1.60
• Ribbon and sticker: $0.25
• Total: $13.85

At a 60% margin: 13.85 ÷ 0.40 = $34.63 per box. If boxes like yours sell for $30 where you are, your margin would be (30 − 13.85) ÷ 30 = 54%. Now you know what that gap costs and you can decide.

What the example shows. In hand-rolled truffles, your time is the biggest line: $0.71 of every $1.00. Ingredients matter, but so do minutes: 30 minutes saved per batch is $9.00, or $0.12 per truffle (9.00 ÷ 76). Had you costed only the recipe chocolate (0.4 kg of coating, no loss) over 80 pieces, ingredients would have looked like $0.23 a truffle instead of $0.26.

How to bring the cost down without cutting quality

• Bigger batches. What stays in the bowl and on the fork does not grow much with batch size; spread over more pieces, it weighs less.
• Buy by the kilo, not the bag. Couverture comes in several bag sizes. The unit price tool tells you which is really cheaper per kilo.
• Look after recovered chocolate. Keep it clean and dry so it goes back in.
• Time each step. Rolling and dipping are where the minutes go. Set up the bench so centres, chocolate, cocoa and cups are in one line, then time the batch again.

Chocolate and nuts go up in price often. The guide on chocolate, nuts and premium ingredients shows how to protect your margin when that happens, and the one on how to price desserts and sweets has the full method for your whole range.

Do it with the calculator

In the food cost calculator, enter the chocolate used, the filling, the cups, the box and the pieces that come out right; it returns the cost per piece and per box and the price for your margin.
