It's safe to say that many people melted over the pictures of Prince George arriving at school for his first day. It's been revealed that the third-in-line to the throne will be known by his teachers and classmates as 'George Cambridge', despite his official title being His Royal Highness Prince George of Cambridge.
But because his parents, Prince William and the Duchess of Cambridge, have decided to send him to Thomas's Battersea private school, the fees for his education are going to be high.
Like, really high.
According to the Mirror, one year at the exclusive school costs £17,604 ($23,044) and increases when Prince George reaches year three. If everything goes according to plan, the Royal youngster is expected to stay at the school until year eight, and by then his school fees will have shot up to £172,116 ($225,204).
The four-year-old could then follow in his dad's and uncle's footsteps and go to Eton - and that's where things get even more pricey.
The cost per term is a staggering £12,910 ($16,891), which could accumulate to more than £360,000 ($470,967) by the time he's finished school. Even though he's a Royal, that doesn't mean that he, or his family, avoids paying school fees.
It's understood that the Prince Charles will be paying for the education, as he already foots the bill for Prince William and Prince Harry's expenses. The Duke of Cambridge obtains his vast wealth from his even vaster estate, the Duchy of Cornwall.
That land covers a whopping 135,000 acres, or 550 km2 over 24 counties. According to financial statements produced in 2013, the duchy was valued at £763 million ($998 million), with an annual profit of £19 million ($24.8 million).
But if you thought Prince George's expected total schooling bill was large, it's a drop in the ocean compared with how much it costs to fund Kate, Will and Harry's activities, which range from their Royal duties to the Duchess' dresses. That total currently stands at an eye-watering £2.5 million ($4.5 million).
And that's all before Princess Charlotte starts school - with a third baby on the way, those bills will just keep adding up.
