3. Future price of an asset To estimate the cost of an item after 1 year we increase the price by the percentage inflation rate To estimate the cost of an item after 1 year we increase the price by the percentage inflation rate Example: A house is currently worth $350,000. If the inflation rate is 5% p.a. estimate the cost of the house after one year

4. Future price of an asset When calculating the future cost of an item several years ahead, the method of calculating is the same as compounding interest When calculating the future cost of an item several years ahead, the method of calculating is the same as compounding interest A = P (1 + R ) n x t 100 x n Where P=original price, r = inflation rate (%), n = no of payments a year, t = time of in years

5. Worked example 1. The cost of a house is $350,000. If the average inflation rate is 5% p.a., estimate the cost of the house after 5 years. 2. Tina purchases a rare stamp for $150. It is anticipated that the value of the stamp will rise by 8% quarterly. Calculate the value of the stamp after 10 years, correct to the nearest $10
