How the Purchase Ratio is calculated
Your qualifying purchases divided by the reference price of your Quota Bag. A Purchase Ratio of 1.00:1 means you have spent the same amount as your bag. 2.00:1 means twice that amount.
Purchase Ratio Calculator
Pre-spend is what collectors call the purchases you make at Hermès before being offered a quota bag such as a Birkin or Kelly. The Purchase Ratio is how MyQuotaBag measures it: your purchases except bags and Small Leather Goods, divided by the price of your Quota Bag.

What counts toward your Purchase Ratio?
Hermès does not publish an official formula. This is simply how MyQuotaBag calculates it: every category counts except Bags and Small Leather Goods.
Counts
- Ready-to-Wear
- Shoes
- Silk
- Home
- Fine Jewelry & Watches
- Fashion Jewelry
- Belts
- Petit h
- Other
Does not count
- Bags
- Small Leather Goods
- Pieces marked Gifted
- Purchases you choose to exclude
Enter prices before tax. A purchase in another currency is converted to yours; a receipt scanned in another currency starts excluded and you can include it. Collectors disagree on purchases made in another boutique, in another country or online: choose your own rule and apply it the same way every time. What collectors report about pre-spend is summed up in the Collector Guide.
About the Purchase Ratio
Why bags and Small Leather Goods are excluded
The Purchase Ratio describes what you buy around the bags, not the bags themselves. Most collectors keep bags and Small Leather Goods out of it and MyQuotaBag does the same.
Common ranges in client conversations
Observations from public discussions, not official rules.
These reports come from collectors who were offered a bag. They say nothing about collectors who are still waiting, so a ratio cannot be read as a probability.
View the underlying MyQuotaBag benchmark, with how many reports it comes from.
What the Purchase Ratio does not measure
Collectors often mention SA relationship, time in boutique and consistency. No number captures them. The Insider Guide covers the broader context.
Why people track it anyway
A personal benchmark you can update over time. Without a number, spending feels abstract. With one, your own history becomes easier to read.
Track every purchase clearly.
The calculator gives you a snapshot. MyQuotaBag keeps the full journey organized on your iPhone: purchases, your Quota Bag and dream items, boutique visits, Sales Associate notes and your Purchase Ratio as your history grows. When you use Scan, the receipt image you select may be sent to an external AI service solely to read the purchase details and you review everything before saving. Manual entry adds a purchase with no image.
- Scan receipts, no spreadsheets
- See your Purchase Ratio over time
- Save dream items, visits and SA notes
- Private by design
Observations only. Your Purchase Ratio is a personal tracking reference and does not predict an offer.
