You might think you’ve heard all about the £9.30 charge in your local currency.
But this is a tiny percentage of the cost to the taxpayer, according to a new study.
It says the cost rises with inflation and that the cost per pound has risen by just 0.4% a year since 2004.
So why is this?
BBC News’ David Bell explains.
What are the figures?
The cost of borrowing to finance the cost rise of inflation Since 2004, the average annual cost of interest has increased by 0.2% a time.
It’s been that way for the past 15 years, rising by just 1.6% a quarter.
But in recent years the cost has increased faster than inflation, rising at a rate of 4.2%.
That’s because the rate of inflation is much higher than that of the real economy.
The cost per cent of GDP has increased 1.9% a month over the past year.
So the cost each year is rising at almost twice the rate as the economy is growing.
What is the inflation rate?
The Treasury publishes data about the inflation rates for different years.
The annual rate is the annual rate over a period of 10 years.
A rising inflation rate is a sign of rising inflation, while a falling rate is not.
So if the rate rises at 1% a week, the cost for borrowing each year will rise by 0:1.
So, over the course of a decade, the inflation will have risen by 0 to 1%.
The figures for the cost increase in inflation are from the Office for National Statistics (ONS).
The cost rises in inflation Since April 2006, the annual inflation rate for the UK has been 2.8%.
So if inflation rises at 3% a day, the yearly cost will increase by 1.8% a decade.
That’s what we’ve been seeing over the last 10 years: inflation rises over time, and rises over a longer period, so you can see that the rise in the cost is much bigger than the rise over a shorter period.
But what about the Treasury’s figures?
They are based on data from April 2006 onwards.
So it’s not a perfect measure, and we need to adjust for inflation.
But there’s one more thing to consider: the CPI inflation rate was higher than the CPI before April 2006.
This is because the CPI is calculated by dividing the number of goods and services in the economy by the number in the shop price index.
So a rise in inflation in the CPI will tend to affect the price of goods sold by businesses.
The CPI was higher in the year before April, but it dropped in the years after, meaning that if we take into account the effect of inflation, the price rises in April would be smaller.
So by the end of April 2018, the CPI had risen by 1%, and the cost had risen at 3%.
What’s the cost in inflation?
The government says the total cost of the government’s spending is £6.9 trillion per year.
This means that the government spends £1,000 of every £3 it collects in taxes.
So that means the total value of the debt is £3,200.
But if we assume that each year, the government pays out £1 for every £2 it collects, the total debt is still £3.18 trillion.
The government spends the money it collects on interest payments on its debt, which is why inflation rises so much faster than GDP.
So as long as inflation stays at 3%, the total interest payments will rise faster than the debt rises.
What about the impact of interest payments?
The impact of inflation on interest paid on the government debt The government has already said that the interest payment rate on the debt will increase if the government has higher debt than it has money.
This could happen if inflation were to rise by a further 3%.
The Treasury has also said that interest payments, in the form of higher interest rates, will not be allowed to rise more than the rate in effect in April 2018.
So we don’t know exactly how the interest payments are paid.
But the Treasury has said that there will be a further increase in the rate when inflation rises by another 3%.
So the total amount of interest that’s paid will continue to rise in line with the rate.
That means that, if inflation stays above 3%, interest payments could increase by a maximum of £6,600 per year by 2020, or £14,400 a year by 2036.
That will be higher than in April 2017, when the government paid £1.20 for every 1,000 pounds it collected in interest payments.
The impact on the public finances The Government’s plan to cut interest payments has also been criticised by some economists.
Professor Peter Hirst of the University of Warwick, one of the most influential economists in the field, said that reducing interest payments by 3% would not make any difference to the public funds because the money that the UK is borrowing from overseas would still be coming back to the UK.
