Cost per sandwich is the price of the tape needed to install one tape-in weft pair: two double-sided tabs. Divide the pack price by the number of tabs, then double it. It lets you compare packs of different sizes fairly. Vanity's Replacement Tape Tabs are $45 for 60 tabs, which is $0.75 a tab and $1.50 a sandwich.
Tape is sold in pack counts that do not line up from brand to brand, and some of it by the roll. The sticker price tells you almost nothing until you turn it into the cost of one bond.
This entry defines that unit and shows the arithmetic. What a whole move-up costs, salon or home, is on its own page.
What does cost per sandwich mean?
Cost per sandwich means the tape cost of one installed tape-in bond. In the sandwich method, two wefts close around a thin section of natural hair, and each weft carries one double-sided tab, so one sandwich uses two tabs. Cost per sandwich is therefore twice the cost per tab.
Stylists use it when pricing a move-up or a retail tape order. Wearers doing their own move-ups use it to work out whether a cheaper pack is actually cheaper. It covers tape only. Hair, remover, tools and labour are separate lines. For how the sandwich itself works, see the move-up entry.
How do you work it out?
Cost per sandwich equals pack price divided by tabs in the pack, multiplied by two. Or, if the pack states sandwiches, pack price divided by sandwiches. For tape sold on a roll, first work out how many tab lengths the roll cuts into at your tab size.
| Step | Vanity Replacement Tape Tabs |
|---|---|
| Pack price | $45 |
| Tabs in the pack | 60 |
| Cost per tab | $45 ÷ 60 = $0.75 |
| Cost per sandwich | $0.75 × 2 = $1.50 |
| Sandwiches per pack | 30, roughly one full head |
Prices from vanityhairsolutions.com on 2026-10-27. Tape only.
Multiply cost per sandwich by the number of sandwiches in your install to get the tape cost of one move-up. Thirty sandwiches at $1.50 is $45. A smaller install needs fewer.
Why is it better than comparing pack prices?
Pack prices hide count differences. A cheaper pack with fewer tabs can cost more per sandwich, and a large bulk pack can look expensive while being cheaper per bond. Cost per sandwich puts every pack on the same unit, so the comparison is about price, not packaging.
It still does not capture everything. A tab that slips at week three costs you a second sandwich, and one that leaves residue costs time and hair at removal. Cheap per sandwich is only cheap if the tab lasts the full 6 to 8 weeks. The trade-off between price and hold is compared in replacement tape tabs, ranked.
Common mistakes when using it
The usual mistakes are counting tabs as sandwiches, which halves the real cost, comparing single-sided and double-sided tape as if they were the same unit, and ignoring how long the tape holds. A price per sandwich only compares fairly between tabs of the same size and format.
- Reading "60 pieces" as 60 sandwiches. It is 30.
- Comparing a 4 cm tab with a mini tab on price alone.
- Leaving out shipping on small packs.
- Ignoring wear time. A tab that lasts four weeks costs more per month than one that lasts eight.
Where this fits in the full cost
Tape is the smallest line in a move-up. At $1.50 a sandwich, a full head of tape is $45. Remover adds roughly $0.83 per removal with Vanity's Clean Remover. The salon fee, if you use one, is usually the largest part.
Salon price ranges, home costs and a yearly comparison are in what a tape-in move-up costs.

Questions we get asked
How many sandwiches is a full head?
It depends on hair density and the look. Vanity's 60-tab pack is 30 sandwiches, which is roughly one full head in our salon.
Is cost per sandwich the same as cost per move-up?
No. Cost per move-up adds remover, labour and any new hair. Cost per sandwich is the tape alone.
Does a bigger pack always mean a lower cost per sandwich?
Often, not always. Do the division. Then check the tab size and hold before buying on price.
