What it means
The measure comes from surveys that ask a rotating sample of households a small set of standard questions. Typical questions cover whether the family is better or worse off than a year ago, whether now is a good time to buy a major item, and what they expect over the coming year.
Answers are converted into an index rather than reported raw, so one month can be compared with another. The index is anchored to a base period given the value 100, which means the number only carries meaning relative to its own history, and a reading of 92 tells you sentiment is below the base period, not that the economy is 8% smaller.
The reason businesses care is timing. Sentiment usually turns before the hard data on retail sales and output, because households adjust discretionary plans quickly while wages and employment lag behind.
The link between mood and money is real but loose. People often report gloom while continuing to spend, particularly when employment is strong, so sentiment is best treated as one input alongside card spending, footfall and order books.
Most published indices separate current conditions from expectations, and the gap between the two is the informative part. When current conditions hold up but expectations collapse, households are usually bracing for something specific, and that is the pattern which most often precedes a pullback in discretionary spending.
In practice
Real-world examples.
Example
A national DIY chain sees the expectations component of a sentiment index fall for three consecutive months while current conditions hold steady. It delays a planned $12,000,000 store refit and switches its autumn promotion from fitted kitchens to lower priced paint and tools.
Example
A car finance lender tracks sentiment alongside its own application volumes and finds applications follow the index with a lag of about two months. It uses the relationship to staff its underwriting team ahead of demand rather than reacting after queues build.
Example
A hotel group in a coastal region reads a sharp fall in sentiment and braces for a weak season, but bookings hold up because households substitute domestic breaks for overseas travel. The group learns to read the index alongside travel specific data rather than on its own.
Formula
Calculation
Balance score = % answering "better" - % answering "worse", then add 100
Index = (current balance score / base period balance score) x 100
A survey reaches 1,000 households and asks whether their finances are better than a year ago. Of those, 480 say better, 320 say about the same and 200 say worse, so 48% answer better and 20% answer worse.
The balance is 48 - 20 = 28 points, and adding 100 gives a relative score of 128. If the base period score for that question was 140, the published index reading is (128 / 140) x 100 = 91.4.
Set against last month's reading of 96.2, sentiment has fallen 96.2 - 91.4 = 4.8 points, a decline of 4.8 / 96.2 = 5.0%. A furniture retailer with income elasticity near 3.0 would read that as a reason to trim the next stock order, though a single month rarely establishes a trend.Case study
Seen in the real world.
The following illustrative and fictional case involves Halberd Kitchens, an invented fitted kitchen retailer with fourteen showrooms. Its typical order was $18,000, usually paid over three years, and it carried $22,000,000 of stock and display units.
In one illustrative year the sentiment index fell from 101.5 to 88.0, a drop of 13.5 points or 13.5 / 101.5 = 13.3%. Halberd's own enquiry numbers fell 9% over the same window, and because roughly 70% of orders were credit financed, the conversion rate from enquiry to signed order slipped from 26% to 20%.
Orders therefore fell much further than enquiries: a 9% fall in enquiries combined with conversion dropping from 26% to 20% gives 0.91 x (20 / 26) = 0.70, a 30% fall in orders. The fictional management team cut showroom stock, introduced a $6,000 single wall range and held the sales force steady, reasoning that sentiment driven falls reverse faster than income driven ones.
Watch out
Common mistakes.
- Reading the index level as a percentage, when it is a relative number anchored to a base period set at 100.
- Reacting to a single month's move, when survey samples are small enough that one reading often reverses the next.
- Assuming weak sentiment always means weak spending, since households frequently report pessimism while continuing to spend out of savings or steady wages.
Questions
People also ask.
Is consumer sentiment the same as consumer confidence?
They are close cousins from different survey providers, with confidence measures usually weighting labour market questions more heavily than personal finance questions.
How far ahead does sentiment predict spending?
Typically a few months, and the relationship is strongest for large discretionary purchases and weakest for groceries and utilities.
Which part of the index is most useful for planning?
The expectations component, because it captures what households intend to do next rather than how they judge the position they are already in.
