What is inflation?
Inflation is basically this:  Over time, prices go up! I will now address the 3 points you have listed. Suppose over a period of 10 years, prices have doubled.  Now suppose 10 years ago I earned $100 and bought a nice pair of shoes.  Now today because prices have doubled I would have to earn $200 in order to afford the same pair of shoes.  Thus if I want to compare my earnings this year to 10 years ago, I will need to adjust for the price of goods going up.  That is, I could say that my $100 earnings 10 years ago is the same as having earned $200 today, or alternatively I could say that my earnings of $200 today is equivalent to having earned $100 10 years ago. This is a difficult question because a car is a depreciating asset, which means the real value of the car will go down in value over time. Let us suppose that inflation doesn't exist and the car you bought for $100 today will depreciate to $90 after 1 year (a 10% depreciation). But because inflation does exist, and all prices will be 0.5% higher in 1 years time, we can calculate the true selling price of the car 1 in year as follows: 0.5% of $90 = 0.005*90 = $0.45 Therefore the car will be $90 + $0.45 = $90.45 in 1 years time. If inflation is low, then the repayments do not get much easier to pay back over time because wages have not risen by as much.  Similarly the value of your underlying asset will not increase in value by as much. However as compensation, the interest rates on loans are usually lower when inflation is lower. Therefore generally it is better to get a loan in times of high inflation rather than low inflation, however it really depends on how the much the interest rates are relative to the inflation rate.
