There's no doubt that care-home fees are expensive, but many people massively underestimate how much they can be - on average, to the tune of £16,646 a year.
We asked people to estimate the cost of a private nursing home place in their region, and it seems that 58% would be in for a bit of a shock, having coming up with a figure that falls well short.
Plus, one in 10 underestimated the cost by £837 a week, or roughly £43,500 a year.
The table below shows average weekly fees of nursing homes in regions across England, and the year-on-year increase.
The worst-affected regions for a jump in care home fees between 2018-19 and 2017-18 are the north-east (11.3%), Yorkshire & Humberside (10.9%) and the north-west (10.4%).
However, the least affected areas - the east of England and the south-east - still saw sizeable jumps (7.7% and 7.9%, respectively).
Here's how much money private nursing in a care home costs across the UK, compared with how much people thought it would be - and what this difference amounts to over a year.
Londoners could be in for the biggest shock. They underestimated weekly costs by £649, which works out as £33,748 per year. That's £4,160 more than the average annual salary for full-time employees in the UK, according to the latest figures from the Office for National Statistics.
People in the East Midlands were the closest to reality, underestimating by a still-significant £152 per week.

Populus, on behalf of Which?, surveyed 2,074 UK adults between 16 and 17 May 2018. The data is weighted to be demographically representative of the population.
Figures were calculated by subtracting respondents' estimations of private nursing-care costs per week from the actual cost for their region, as per LaingBuisson data, and performing descriptive statistics on the difference, in England only.
