instead of paying it out. If you are repaying a loan that charges

earn compound interest on your investment, it grows without any
further deposits. You may increase the deposits to raise the efficacy
of the compound interest.

• In fact, they are usually much, much larger, as they contain more periods ttt various interest rates rrr and different compounding frequencies mmm…
• These example calculations assume a fixed percentage yearly interest rate.
• Using shorter compounding periods in our compound interest calculator will easily show you how big that effect is.
• If you wonder how to calculate compound interest, these formulas provide the answer.
• All you need to do is just use a different multiple of P in the second step of the above example.
