This calculator helps you estimate the growth of your money in a Navy Federal money market account. Simply enter your initial deposit, monthly contribution, and the account's APY to see how your balance will grow over time.
How to Use This Calculator
Using this money market account calculator is simple:
- Enter your initial deposit amount in the first field.
- Specify how much you plan to contribute each month.
- Enter the annual percentage yield (APY) offered by Navy Federal.
- Select the term length for your investment.
- Click "Calculate" to see your projected balance.
The calculator will show you how your money grows with compound interest, which is how money market accounts typically work.
Formula Used
The calculation uses the future value of an investment formula with compound interest:
Future Value Formula
FV = P × (1 + r/n)^(nt) + PMT × (((1 + r/n)^(nt) - 1) / (r/n)) × (1 + r/n)
Where:
- FV = Future Value
- P = Principal (initial deposit)
- PMT = Monthly contribution
- r = Annual interest rate (APY)
- n = Number of times interest is compounded per year (12 for monthly)
- t = Time in years
This formula accounts for both your initial deposit and regular monthly contributions, with interest compounded monthly.
Worked Example
Let's say you deposit $5,000 initially and contribute $200 each month to a Navy Federal money market account with a 2.10% APY over 5 years.
| Year | Starting Balance | Interest Earned | Ending Balance |
|---|---|---|---|
| 1 | $5,000.00 | $2,310.00 | $7,510.00 |
| 2 | $7,510.00 | $2,540.00 | $10,050.00 |
| 3 | $10,050.00 | $2,770.00 | $12,820.00 |
| 4 | $12,820.00 | $3,000.00 | $15,820.00 |
| 5 | $15,820.00 | $3,230.00 | $19,050.00 |
After 5 years, you would have approximately $19,050 in your account, assuming the APY remains constant.
