EXP Function in Excel
Returns e raised to the power of a given number.
Syntax
- =EXP(number)
Arguments
- number (required): The exponent to raise e to
Examples
- =EXP(1) - e to the 1st power - Result: 2.718...
- =EXP(2) - e squared - Result: 7.389...
EXP in reporting workflows
- Use absolute references when copying formulas across rows.
- For conditional totals see [SUMIF](/functions/sumif/) and [SUMIFS](/functions/sumifs/).
- Filtered lists may need [SUBTOTAL](/functions/subtotal/) instead of SUM on visible cells only.
Common errors
- Very large numbers may cause overflow
Use cases
- Exponential growth
- Continuous compounding
- Scientific calculations
Frequently asked questions
- What is the EXP function and what is 'e'? EXP returns e (Euler's number, approximately 2.71828) raised to a power. The constant e is fundamental in mathematics for modeling continuous growth, compound interest, and natural phenomena. EXP(1) = e, EXP(2) = e², etc.
- How do I calculate continuous compound interest with EXP? Use =Principal*EXP(rate*time). For $1000 at 5% continuously compounded for 10 years: =1000*EXP(0.05*10) = $1,648.72. This is slightly more than regular compound interest because growth is truly continuous.
- What is the relationship between EXP and LN? EXP and LN are inverse functions. LN(EXP(x)) = x and EXP(LN(x)) = x. If you have a growth rate from LN, use EXP to convert back to a multiplier. Example: LN(2) ≈ 0.693, and EXP(0.693) ≈ 2.
