Formula: Calculate inflation over multiple years in Excel
Formula Generator | 8 months ago
In this guide, we will learn how to calculate inflation over multiple years in Excel using a simple formula. By understanding the variables involved and how to use the formula effectively, you will be able to determine the future value of an initial amount after a specific number of years with inflation taken into account.
To calculate inflation in Excel, we use the formula: =InitialValue * (1 + InflationRate)^NumberOfYears. This formula multiplies the initial value by the inflation rate raised to the power of the number of years. Let's dive into the details of each variable and how to apply the formula in practice.
InitialValue: This represents the starting value to which you want to add inflation. Replace this with the actual value you want to calculate.
InflationRate: This is the rate of inflation expressed as a decimal. For example, if the inflation rate is 3%, you would enter 0.03 in the formula.
NumberOfYears: This indicates the number of years over which you want to calculate the inflation. Replace this with the actual number of years you want to consider.
Please note that this formula assumes a constant inflation rate over the specified number of years. If the inflation rate varies, you would need to use a more complex formula or consider a different approach.
To add inflation to a value over a certain number of years in Excel, you can use the following formula:
=InitialValue * (1 + InflationRate)^NumberOfYears
This formula calculates the future value by multiplying the initial value by the inflation rate raised to the power of the number of years.
Here's a step-by-step explanation of the formula:
InitialValue: This is the starting value to which you want to add inflation. Replace this with the actual value you want to calculate.
InflationRate: This is the rate of inflation expressed as a decimal. For example, if the inflation rate is 3%, you would enter 0.03 in the formula.
NumberOfYears: This is the number of years over which you want to calculate the inflation. Replace this with the actual number of years you want to calculate.
^: This is the exponentiation operator in Excel. It raises the inflation rate to the power of the number of years.
Here's an example to illustrate how the formula works:
Let's say you have an initial value of $1000 and you want to calculate the value after 8 years with an inflation rate of 2% per year.
InitialValue = $1000InflationRate = 0.02NumberOfYears = 8
Using the formula, the calculation would be:
Evaluating this formula would give you the future value after 8 years with inflation applied.
Please note that this formula assumes a constant inflation rate over the specified number of years. If the inflation rate varies, you would need to use a more complex formula or consider using a different approach.

How do you calculate inflation over multiple years in Excel? ›
The basic formula is start_amount * (1 + inf_rate)^years where:
- start_amount is the the original dollar amount - eg $1,000,000.
- inf_rate is the annual inflation rate as a decimal - eg 0.03.
- years is the number of years since the start - eg 0, 5, 10, etc.
How to calculate the average annual inflation rate over a period of years
- Subtract the base year from the target year: $7 - $3 = $4.
- Divide the difference by the base year: $4/$3 = 1.33.
- Multiply this sum by 100 to reach a percentage: 1.33 x 100 = 133%
Start by subtracting the earlier date CPI from the later date CPI (1.32 - 0.23 = 1.09) Divide by B. Then divide this number by the earlier date CPI to get a decimal point answer (1.09 / 0.23 = 4.74) Multiply by 100.
How do I calculate interest rate for multiple years in Excel? ›
Chandoo
- on principal amount P.
- at the rate of interest R.
- for the number of years N.
- and compounded T times per year.
- we can use the formula = P*(1+R/T)^(N*T)
To calculate the average growth rate of your company, you first need to divide the present by the past value, then multiply that number by 1/N (where N is the number of years). Finally, subtract the result by 1, and you'll get the average growth rate.
How do you calculate percentage increase over multiple years in Excel? ›
The growth rate formula looks like this: Growth Rate = (ending value - beginning value / beginning value) x 100.
What is the formula for cumulative inflation? ›
Cumulative inflation is calculated by first choosing a good or basket of goods, and then dividing today's price by the price at the start of the period. Then subtract 1. If the resulting number is greater than 0, the price of that good has inflated.
How much inflation over last 3 years? ›
In 2023, the average rate of inflation was 4.1%. In 2022, the average rate of inflation was 8.0%. In 2021, the average rate of inflation was 4.7%. In 2020, the average rate of inflation was 1.2%.6.
How do you calculate CPI over years? ›
To find the CPI in any year, divide the cost of the market basket in year t by the cost of the same market basket in the base year. The CPI in 1984 = $75/$75 x 100 = 100 The CPI is just an index value and it is indexed to 100 in the base year, in this case 1984. So prices have risen by 28% over that 20 year period.
Subtract the CPI of the start date from the CPI of the end date. Divide that number by the CPI of the start date. Multiply this number by 100 and add a percent sign, and there's the inflation rate for that period.
How is inflation measured year over year? ›
The most well-known indicator of inflation is the Consumer Price Index (CPI), which measures the percentage change in the price of a basket of goods and services consumed by households.
Is inflation measured over 12 months? ›
Usually people measure inflation by comparing the cost of things today with how much they cost a year ago. The average increase in prices is known as the inflation rate. So if inflation is 3%, it means prices are 3% higher (on average) than they were a year ago.
How do you calculate interest rate over multiple years? ›
Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. The total initial principal or amount of the loan is then subtracted from the resulting value. Katie Kerpel {Copyright} Investopedia, 2019.
How to compound inflation in Excel? ›
To adjust for inflation in Excel, follow these steps:
- Determine the inflation rate.
- Subtract the inflation rate from 1.
- Multiply the original amount by the result of step 2.
- Repeat step 3 for each year being adjusted.
If you have an annual interest rate, and a starting balance you can calculate interest with: =balance * rate and the ending balance with: =balance+(balance*rate) So, for each period in the example, we use this formula copied down the table: =C5+(C5*rate) With the FV function The FV function can...
How do I calculate the present value of multiple years in Excel? ›
PV can be calculated in Excel with the formula =PV(rate, nper, pmt, [fv], [type]). If FV is omitted, PMT must be included, or vice versa, but both can also be included. NPV is different from PV, as it takes into account the initial investment amount.
How to calculate inflation rate between two years using GDP? ›
Inflation rate is just the percentage change in GDP deflator from one period to the next. Mathematically, we can write it as GDP deflator of year 2 subtracted by GDP deflator of year 1, divided by GDP deflator of year 1, and then multiplied by 100.
