How to Use This Calculator

- Click "Calculate" to see your estimated earnings.
The calculator will display your total earnings, the interest earned, and a chart showing your balance growth over time.
Formula Used
The calculation uses the 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 (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 time the money is invested or borrowed for, in years
For this calculator, we assume interest is compounded quarterly (n=4).
Worked Example
Let's say you deposit $5,000 in a Capital One money market account with a 2.10% APY. Here's how the calculation works over 5 years:
A = $5,000 × (1 + 0.021/4)4×5
A = $5,000 × (1.00525)20
A ≈ $5,000 × 1.1274
A ≈ $5,637
After 5 years, you would have approximately $5,637, earning $637 in interest.
