Study Notes
Simple Interest
- Simple interest calculates interest only on the principal amount.
- Formula: Interest = Principal × Rate × Time
- Example: If you borrow $1000 at 5% annual interest for 2 years, the simple interest is $100.
Compound Interest
- Compound interest calculates interest on both the principal amount and the accumulated interest from previous periods.
- It results in faster growth compared to simple interest.
- Formula: A = P(1 + r/n)^(nt) where:
- A = the future value of the investment/loan, including interest
- P = the principal investment amount (the initial deposit or loan amount)
- r = the annual interest rate (decimal)
- n = the number of times that interest is compounded per year
- t = the number of years the money is invested or borrowed for
Semi-Annual Interest
- Interest compounded twice a year.
- 'n' in the compound interest formula would be 2.
Monthly Interest
- Interest compounded twelve times a year.
- 'n' in the compound interest formula would be 12.
Compounded Quarterly Interest
- Interest compounded four times a year.
- 'n' in the compound interest formula would be 4.
Compounded Continuously
- Interest compounded an infinite number of times per year.
- Formula: A = Pe^(rt)
- where:
- e is the mathematical constant approximately equal to 2.71828
- Other variables remain the same as in the compound interest formula.
- Results in the fastest growth among these compounding methods.
Key Differences Summary
- Comparing the different types of interest calculations, compounding more frequently leads to a larger final amount.
- Continuous compounding represents the theoretical maximum potential growth.
