Estimate a conference bag’s cost per impression (CPI) by dividing the relevant campaign cost by the impressions you reasonably expect the bags to generate. For a per-bag estimate, divide the all-in cost of one bag by its estimated lifetime impressions. ASI’s 2026 benchmark is 4,900 lifetime impressions for a promotional bag, but that population-level estimate is not a promise about any particular conference order.
Calculate CPI using matching costs and impressions
For the whole campaign, use:
CPI = total relevant campaign cost ÷ estimated total impressions

For one bag, use:
CPI per bag = all-in cost per bag ÷ estimated lifetime impressions per bag
Make sure the numerator and denominator describe the same scope. Divide total campaign spend by campaign impressions, or divide per-bag cost by that bag’s estimated impressions. Comparing the full order bill with the lifetime impressions of a single bag will produce a misleading result.

To express the result as cost per thousand impressions (CPM), multiply CPI by 1,000. Keep the labels distinct: CPI is the cost of one impression; CPM is the cost of 1,000.
For example, an illustrative $6 bag divided by 4,900 impressions equals about $0.00122 CPI, or $1.22 CPM. This is arithmetic using ASI’s 2026 impression benchmark and an illustrative bag cost—not a reported purchase price or supplier quote.

What ASI’s 2026 benchmark tells you
The Advertising Specialty Institute’s 2026 Global Advertising Impressions Study assigns promotional bags an average of 4,900 lifetime impressions. ASI says its category estimate is calculated from how long consumers keep an item, how often they use it, and how many people they encounter while using it. The figure offers a reference point for planning, not a measured result for your event or a guarantee that every distributed bag will be kept, reused, or seen.
ASI’s 2026 reporting also says 84% of surveyed consumers would keep a promotional bag for at least one year and 92% would use one at least monthly. These are survey-based category findings; individual bags and audiences can behave differently. ASI’s related 2026 article on branded tote bags describes CPI as about one-tenth of a cent using a $6 average tote price and nearly 5,000 lifetime impressions.

Those figures are useful as a benchmark, but a specific order’s result depends on whether attendees take the bag, carry it beyond the event, keep it, and use it where other people can see the branding. A durable, useful, attractive bag may have a better chance of staying in circulation; it still cannot guarantee a particular impression count.
Build a conference-specific impression estimate
Rather than assigning every ordered bag the ASI average, estimate the exposures your own event could plausibly produce. State your assumptions and use low, middle, and high scenarios when attendance behavior or future reuse is uncertain.

- WASHING NOTICE: cleaning of 100% cotton bags is not recommended. The washing shrinkage rate exceeds 10%. Should it be seriously dirty, it is recommended to wash it in cold water by hand. Hang dry is necessary before high- temperature ironing. Please notice that the fabric may not return to the original flatness. Flash drying and machine wash shall be prohibited.
- WARRANTY: when the bag is broken in a normal use within 1 year, we will reserve for replacement for FREE.
- Bags taken: Estimate how many ordered bags attendees are likely to receive and keep at the event. Do not assume every bag ordered is distributed or carried away.
- Carry-through and retention: Estimate the share of recipients who continue using the bag after the conference and for how long.
- Repeat use: Estimate how often recipients might use it during the period you are counting. Separate expected event-day use from later reuse.
- Visibility: Consider whether the logo will be visible while the bag is carried, rather than covered, folded inward, or hidden among other items.
- Audience encountered: Estimate how many people might see the branding during each use. Avoid treating a single person’s travel route or a large crowd as a guaranteed audience.
A simple scenario can be expressed as bags actually taken × expected visible uses per bag × people who see the logo per use. For lifetime estimates, include the expected duration of reuse in the visible-use assumption. These inputs are planning assumptions, not independently verified audience counts, so document them alongside the resulting CPI.
Include the costs that belong in the calculation
Use the actual quote for the bag and the complete order costs that support the impressions being counted. Relevant charges can include the bag invoice, printing or embroidery, setup or art charges, freight, and other order expenses.

For landed per-bag cost, divide the total order cost by the number of bags received. If some received bags will not be distributed, you can also calculate an effective cost per bag actually distributed by dividing the same total by the estimated number handed out. Use that denominator consistently with an impression estimate based only on distributed bags.
Estimate and compare an order step by step
- Get a quote for the actual order. Confirm the bag, quantity, print method, setup or art charges, shipping, and delivery timing.
- Calculate the matching cost basis. Work out total landed order cost, cost per bag received, and—if useful—effective cost per bag distributed.
- Set low, middle, and high exposure scenarios. For each, state assumptions for bags taken, retention, reuse, logo visibility, and people likely to see the bag in use.
- Divide cost by the impressions for the same scope. Label the result CPI; multiply it by 1,000 only when you want CPM.
- Compare practical fit as well as CPI. Consider durability, capacity, usefulness to the audience, branding visibility, substantiated sustainability claims, customization costs, order quantity, and delivery risk.
How to interpret sustainability and older figures
ASI’s 2026 study reports that surveyed consumers said they would have a more favorable view of an advertiser when a promotional bag was sustainable (86%) or socially responsible (87%) compared with a standard item. These are stated consumer attitudes, not evidence of increased sales, a higher impression count, or campaign ROI. Make sustainability claims only when they can be substantiated for the bag you are ordering.
An earlier ASI 2023 bag snapshot reported 1,940 lifetime impressions and one-tenth-cent CPI for a $2 non-woven tote. The 2026 study’s 4,900-impression estimate is the newer benchmark. The cited pages do not explain differences in methodology or sampling between editions, so the two estimates should not be combined into a trend or treated as directly comparable measurements.
