7% = Expected inflation inflation rate 15 = Number of years 13795 = is the amount you required per month after 15 years instead of present 5,000, with an inflation rate of 7%. If the inflation rate is more, the amount also increased accordingly. The same formula you can use to identify the maturity value of your investment after a period of time.
Dave Patton, thank you for looking at this. The issue with the datedif formula is that it is using the same inflation rate for each month. I am trying to create a formula that looks up inflation rates per month from an existing table.
Thanks for this, I have incorporated the formula to calculate years left for a fixed withdrawal and take on board the point regarding inflation. As I am no longer contributing to savings I start with the initial amount and am working backwards to calculate indicative draw-down rates and time-span under various growth/inflation scenarios.
There are many measures of inflation. But in simple terms, inflation is the average rate at which costs increase. But if we know the rate at which a specific costs increases, we use that rate. Typical example: current CPI is around 2%, which we apply to most consumer costs; but for medical expenses, we use 7% inflation.
I'm looking for a formula that gives me an average unit price value that considers annual inflation. For example: Inflation is 2% Year 1, Unit Price is 100.00 Year 2, Unit Price is 102.00 { =100*1.02 } for an average unit price of 101 { =(100+(100*1.02))/2 }.
how to calculate inflation rate in excel lets say, i want to calculation future value in 20 years with interest of 6% and inflation rate of 2% would this formula be correct? or is there any better way? =500/(1+.06)^20*(1+.02)^20
The two are equivalent, when you use the same variable names: r is payment inflation rate, and n is number of years. Also use proper parentheses (also note the last exponent): pmt* (1+r) ^0 +...+ pmt*(1+r)^(n-1) (The formula in your original posting was more correct. I did not realize your mistake in parentheses, unconsciously reading 1+0.03 as ...
I am unsure what formulas I should be using to 1. find the correct CPI and 2. how to adjust the returns for the index with inflation. Below is the following of how I have attempted some steps. I could very well be completely off on my formulas but this is all I could find on the internet. Any help would be amazing.
I am interested to know whether there is a compound interest formula which takes inflation into account. I am familiar with the compound interest formula. The type of calculation I'm looking to do is Monthly investment of: $250 Annual interest rate: 4% Annual inflation rate: 3% Period of investment: 40 years Hoping someone can help. Thanks. Mac
So, I'd like to find out if we can do an inflation calculation in Excel. Here's what I'd like to do/know: A1 (Current Year) A2 (Future Year) A3 (Inflation percentage) A4 (Future value) A5 (Future value in today's dollars) My idea is that I'd like to make the money 30 years from now worth 3% less each year until a year I specify (2005 at the ...
