Welcome to the world of the DINK - that's dual income, no kids. In recent months the term has been plastered across social media as child-free couples extol the virtues of their lifestyles.
But does it really pay to not have children?
Experts are warning that the decision isn't that simple - and couples who opt out of parenthood could lose out in the long run as they miss key benefits like Child Tax Credit and, crucially, later life care.
Personal finance expert Dr Roger Gewolb told Dailymail.com: 'Of course there's an immediate financial benefit to not having kids. But down the line it's important to think about later life care and who's going to look after you when you're older.
'It'd be interesting to see what these DINKs think of their decision in 10 to 12 years.'

The term 'DINK' dates back to 1987 and was first coined by the Los Angeles Times when researchers noted that stalling incomes were deterring would-be parents from starting families.
But it has been repopularized on social media amidst red-hot inflation and high childcare costs. The hashtag ''#DINK' now has 205 million views on TikTok.
Among the influencers purporting the values of a child-free lifestyle is Hilary Bowles.
Bowles shared one video of herself and her partner on holiday in Bora Bora, with the caption: 'In our married, travel the world, pre-kids, dual income era.'
In another, she posted a clip of herself opening a Chanel shopping bag in front of the Eiffel Tower in Paris - followed by a montage of her enjoying luxury vacations on boats, beaches and safari parks with her husband.
She sarcastically captioned the video: 'You're 30, you should be having kids.'
Last year, the financial management site Mint Intuit found that the cost of raising a child to the age of 17 had ballooned to $292,017 - hooked on figures from the Department of Agriculture.
The estimate was based on a middle-income family of four and is before any college costs are accounted for.
The study found 29 percent of that money came from needing a bigger property. For a married couple with two children and an income of $104,127 before tax, this would mean $84,685 over 17 years.
The second highest expense was food which accounted for 18 percent - or $52,263 - out of the family budget.

Meanwhile, childcare and education set parents back around $46, 723 on average and transportation cost $43,802, according to the data.
Healthcare, clothing and miscellaneous expenses were also accounted for.
The exact costs of having a child in the next few years are hard to pin down due to wider economic uncertainty and volatile inflation - which peaked at 9.1 percent in June 2022 but now hovers at a more stable 4.9 percent.
It is little wonder then that birth rates have plummeted. In 2020 - when the world was in the throes of the Coronavirus pandemic - just 3.4 million babies were born in the US, down four percent on the year before.
It marked the lowest number of children born since 1979. Since then birth rates have picked up slightly, by 0.9 percent in 2021 and by the same amount again in 2022.
A study by Pew Research Center in 2021 found that 44 percent of non-parents aged between 18 and 49 said they were not at all likely or not too likely to ever have children - up by 7 percent since 2018.
Couples cited financial concerns among their reasons for staving off the decision.
But chartered financial consultant Bill Ryze points out that couples often fail to consider the Government support that comes with having children.
'Currently, the Child Tax Credit is a maximum of $2,000 a year for a child below 17 years,' Ryze said.
'So, while raising a kid is expensive, at least you are eligible for a refund. Without kids, your tax refunds will be lesser than they would have been with kids.'
IRS figures show the average American family receives $3,600 a year for each child under the age of six and $3,000 for those aged 6-17.
Ryze added that those without children may not be as focused in looking after their finances.

As couples stand to save nearly $500,000 by refusing to have two children, Ryze warned it was 'prudent' they find a suitable investment for this money to save them during retirement.
'Most parents are driven by the desire to provide a desirable life for their kids and worry about how much inheritance they live to their children.
'So, being child-free sometimes may give you less pressure in terms of savings and investment since inheritance is not a priority.'
On the flipside, he notes that childless households are better placed to weather economic uncertainty as it is easier for them to downsize their homes or move away from expensive areas - without worrying about school locations.
But the biggest crunch point comes in the form of elderly social care fees.
Parents can often rely on their children to look after them in later life and help out if they need extra care for conditions such as dementia.
Those without children risk having to move into a nursing home for support as they age.
The average cost of a US nursing home is now $2,432 a month, according to data from SeniorHomes. Just five years in residential care for one person would therefore cost $145,920.
It means those who choose to forgo children will have to plan carefully to make sure they have enough money to shoulder these fees.
Dr Gewolb said: 'Ultimately having children is an emotional decision not a financial one.
'And it's important to know that couples can always change their mind - they can enjoy the DINK lifestyle while they're young and then they can always consider children at a later date.'
