It's been two years since Meghan Markle and Prince Harry have tied the knot, and nine years of Kate Middleton and Prince William being married.

Since weddings, even for the middle-class citizens, cost some hefty penny, many people wonder how much the entire royal wedding shindig would set back the monarchy and the British taxpayers.

Royal weddings are known to be extravagant, and any commoner can say that each one of the weddings is always pricey.

The ceremony will always feature only the most elite wedding gowns, the flowers, the food, and is expected to be one of the most expensive celebrity weddings of all time.

The lavish affair features TV crews broadcasting the event around the world.

Outside the British church, crowds are enormous, that the security costs alone will add up to millions.

According to reports, the royal family pays for the wedding itself, and frequently, the bride will cover only the cost of the dress.

However, the security costs are paid by the British government.

In a survey conducted by YouGov, 57% of adult respondents in the UK believe that the royal family should be paying for the security on the big day, in addition to the wedding.

1% of the respondents think that the government should pay for the entire royal wedding event.
