Consumer Research
Female purchasing power is permission to enter the market. Not a strategy.
Everyone quotes the number. Almost nobody changes a single decision because of it.
Female purchasing power is the total value of consumer spending women control or influence. The figure most often cited is $31.8 trillion globally. It is real, it is large, and on its own it is useless. Volume tells you the market is worth addressing. It tells you nothing about what would make her choose you over the brand next to you on the shelf. This page covers where that authority comes from, and what to do with it.

The drivers
Four structural forces behind the number.
01
Household procurement authority
In most households a woman is the buyer of record for categories she does not personally consume: her partner's groceries, her parent's medication, her child's insurance. Her spending power is larger than her personal preferences, which is why preference research alone underestimates the market.
02
Earned income and delayed partnership
Women are earning, marrying later, and controlling their own accounts for a longer stretch of adult life than any prior generation. That extends the window of independent purchasing behavior into categories that were historically joint decisions, notably automotive, investing, and real estate.
03
Longevity and inheritance
Women outlive their partners, so a large share of the wealth transfer lands with them at least once before it moves to the next generation. This is the Legacy Consumerism™ effect, and it means the brand relationship being negotiated today is the one that survives the transfer.
04
Cultural gatekeeping
Beyond direct spending, women set the standard of what a category is allowed to look like. Recommendations, group chats, and community reviews function as distribution. Her influence over other people's purchases is not counted in the trillion-dollar figure at all.
Conversion
How to turn spending power into revenue.
Start by naming which driver your category actually sits on. A grocery brand is competing on household procurement. A wealth manager is competing on longevity and inheritance. A skincare launch is competing on cultural gatekeeping. These require different research, different proof, and different media.
Then audit the friction. Purchasing power converts where the cost of getting it wrong is lowest, which is why return policies, service response, and clarity of pricing move more revenue in women's categories than the creative does.
Finally, measure exits, not just acquisitions. Women rarely complain their way out of a brand. They replace it quietly, and the reason shows up in the data a quarter too late. The full decision process is broken down in how women shop.
The comparison
Do women spend more than men? Depends what you count.
The two most common versions of this question — do women spend more than men and who spends more money, men or women — get opposite answers depending on whether you measure per person or per household. Both answers are below, with the source for each figure.
| Question | What the data shows | Figure | Source |
|---|---|---|---|
| Do women spend more than men? | Not in personal income terms. Women direct a far larger share of household spending. | ~85% of household purchase decisions | Bridget Brennan, Why She Buys (industry estimate) |
| Who spends more money, men or women? | Counted by decision rather than by wallet, women influence the majority of consumer spending. | $31.8T influenced globally | EY / Bridget Brennan (industry estimate) |
| Who decides household healthcare spending? | Predominantly women, including decisions made on behalf of other adults. | ~80% of healthcare decisions | U.S. Department of Labor (widely-cited) |
| Where is household spending actually measured? | At the household (consumer unit) level, not per person — which is why per-person earnings data misreads who buys. | Consumer Expenditure Survey methodology | U.S. Bureau of Labor Statistics |
| How much wealth is transferring, and to whom? | A large share passes through women first, because women outlive their partners on average. | $84T transferring through 2045 | Cerulli Associates |
Figures are reported as published by the named source. Several widely-circulated spending statistics originate as industry estimates rather than government data and are labelled as such.
