What is the purpose of using timelines in compounding interest calculations?
What is the purpose of using timelines in compounding interest calculations?
- To calculate the accumulated value at the end of each period
- To visualize the periods and changes in compounding and interest rates over the term of the investment or loan (correct)
- To adjust the principal for deposits or withdrawals
- To determine the annual interest rate
When interest rates change or additional deposits/withdrawals are made, how should the timeline be handled?
When interest rates change or additional deposits/withdrawals are made, how should the timeline be handled?
- Stop the calculation and restart with the new interest rate
- Break the timeline into segments and calculate each period separately (correct)
- Average the interest rates and calculate the accumulated value for the entire term
- Ignore the changes and calculate the accumulated value for the entire term
What is the formula to calculate the accumulated value in compounding interest?
What is the formula to calculate the accumulated value in compounding interest?
- A = P(1 + i)^n
- A = P(1 + i-np)
- A = P(1 - i/p)^(np)
- A = P(1 + i/p)^(np) (correct)
