A Certain Loan Program Offers An Interest Rate Compounded Continuously. Assuming No Payments Are Made, How Much Would Be Owed After 6 Years On A $3800 Loan? Round To The Nearest Cent.
Understanding the Concept of Continuous Compounding
Continuous compounding is a method of calculating interest on a loan or investment where the interest is compounded at a rate that is constantly applied over time. This means that the interest is applied not just at the end of a fixed period, but rather at every instant. In other words, the interest is compounded continuously, rather than at discrete intervals.
The Formula for Continuous Compounding
The formula for continuous compounding is given by:
A = P * e^(rt)
Where:
- A is the amount of money accumulated after n years, including interest
- P is the principal amount (the initial amount of money)
- e is the base of the natural logarithm (approximately equal to 2.71828)
- r is the annual interest rate (in decimal form)
- t is the time the money is invested for, in years
Applying the Formula to the Given Problem
In this problem, we are given a loan of $3800 with an interest rate compounded continuously. We need to find out how much would be owed after 6 years, assuming no payments are made.
Given Values
- P = $3800 (the initial loan amount)
- r = 0.06 (6% annual interest rate, in decimal form)
- t = 6 years (the time period for which the interest is compounded)
Calculating the Amount Owed
Using the formula for continuous compounding, we can calculate the amount owed after 6 years as follows:
A = 3800 * e^(0.06*6) A = 3800 * e^0.36 A ≈ 3800 * 1.4305 A ≈ 5442.90
Rounding to the Nearest Cent
Rounding the calculated amount to the nearest cent, we get:
A ≈ $5442.90
Conclusion
In this problem, we used the formula for continuous compounding to calculate the amount owed after 6 years on a $3800 loan with a 6% annual interest rate. The calculated amount is approximately $5442.90, rounded to the nearest cent.

Q: What are some common mistakes to avoid when using continuous compounding?
A: Some common mistakes to avoid when using continuous compounding include:
- Not accounting for compounding frequency: Continuous compounding assumes that interest is compounded at every instant, but in reality, interest is often compounded at discrete intervals.
- Not considering the impact of inflation: Continuous compounding assumes that the interest rate remains constant over time, but in reality, inflation can erode the purchasing power of money.
- Not using the correct formula: The formula for continuous compounding is A = P * e^(rt), but it's essential to use the correct values for P, r, and t.
Q: How can I calculate the future value of an investment using continuous compounding?
A: To calculate the future value of an investment using continuous compounding, you can use the formula A = P * e^(rt), where A is the future value, P is the principal amount, e is the base of the natural logarithm, r is the annual interest rate, and t is the time the money is invested for, in years.
Q: What are some real-world examples of continuous compounding?
A: Some real-world examples of continuous compounding include:
- Compound interest on savings accounts: Many savings accounts offer compound interest, which is a type of continuous compounding.
- Investment returns: Continuous compounding is used to calculate the returns on investments, such as stocks and bonds.
