What is the formula for continuous compounding?

Back

A = Pe^(rt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), r is the annual interest rate (decimal), and t is the time the money is invested for in years.

Front

What is the effect of increasing the interest rate on the amount accumulated with continuous compounding?

Back

Increasing the interest rate will result in a higher amount accumulated over time.

Front

What is the effect of increasing the time period on the amount accumulated with continuous compounding?

Back

Increasing the time period will also result in a higher amount accumulated due to the compounding effect.

Front

How do you calculate the amount after continuous compounding?

Back

Use the formula A = Pe^(rt). Substitute P for the principal, r for the interest rate, and t for the time in years.
