How to calculate the antilog (inverse log) in Excel
Formula (Excel and Google Sheets)
=10^A2Raise 10 to the log value with =10^A2, or use =EXP(A2) for a natural log.

The formula is already in B2, filled down to B6. Change any input and the result updates, or edit the formula to experiment.
How it works
The antilog reverses LOG10: if LOG10(100) is 2, then 10² is 100. Fractional and negative logs work the same way: 10^0.5 is about 3.162 and 10^-1.3 is about 0.0501. The log of 1 is 0, so the antilog of 0 is 1.
=10^A2Result100
A22The value in A2.
10^A2100The ^ operator raises to a power.
In Google Sheets
The same formula works in Google Sheets: =10^A2. We ran it in Google Sheets mode on the same data and it returns the same results.
Other ways to do it
Each one was run on the same example sheet.
| Formula | Result | When to use it |
|---|---|---|
| =POWER(10,A2) | 100, 3.16227766, 0.05011872336… | The function form of the same calculation. |
Common mistakes
- Use the same base you took the log with. Values from LN need EXP, not 10^.
- Large logs overflow: 10^309 returns #NUM! because it is beyond the largest number Excel can store.
Try it yourself
Same data, empty answer cell. Your formula is graded instantly, then re-checked on changed data, so a typed-in number won't pass.
Calculate the antilog (inverse log)
B2, calculate the base-10 antilog of the value in A2, then fill down to B6.Questions
How do I get the antilog of a natural log?
Use =EXP(A2).
How do I get the antilog in base 2?
Use =2^A2.
