This money market interest calculator helps you determine your monthly savings from money market accounts. Money market accounts typically offer higher interest rates than savings accounts, making them a good choice for short-term savings goals.
How to Use This Calculator
Using this calculator is simple. Just follow these steps:
- Enter the principal amount (the initial amount of money you want to invest).
- Select the interest rate (APY) offered by your money market account.
- Choose the compounding frequency (typically monthly).
- Enter the time period in years.
- Click "Calculate" to see your monthly savings and the total amount earned.
The calculator will display your monthly interest earned and the total amount in your account after the specified time period.
Formula Used
The money market interest is calculated using the compound interest formula:
Compound Interest Formula
A = P(1 + r/n)^(nt)
Where:
- A = the future value of the investment/loan, including interest
- P = the principal investment amount
- r = the annual interest rate (decimal)
- n = the number of times that interest is compounded per unit t
- t = the time the money is invested or borrowed for, in years
For monthly savings, we calculate the monthly interest earned by dividing the total interest by the number of months in the time period.
Worked Example
Let's say you deposit $10,000 into a money market account with an annual percentage yield (APY) of 2.5%, compounded monthly, for 5 years.
- Principal (P) = $10,000
- Annual interest rate (r) = 2.5% or 0.025
- Compounding frequency (n) = 12 (monthly)
- Time (t) = 5 years
Using the formula:
Calculation
A = 10,000(1 + 0.025/12)^(12*5)
A ≈ $11,338.99
Total interest earned = $1,338.99
Monthly interest earned = $1,338.99 / (5 * 12) ≈ $22.32
After 5 years, you would have approximately $11,338.99 in your account, earning about $22.32 per month in interest.
