How to Use This Calculator

To use the Capital One Money Market Calculator:

  1. Enter your initial deposit amount in the "Initial Deposit" field.
  2. Select the current APY offered by Capital One's money market account.
  3. Enter the number of years you plan to keep the money in the account.
  4. Click the "Calculate" button to see your projected balance.

The calculator will display your projected balance after the specified number of years, taking into account the compounding interest earned on your initial deposit.

Formula Used

The calculation is based on the compound interest formula:

A = P × (1 + r/n)^(nt) where: A = the future value of the investment/loan, including interest P = principal investment amount (the initial deposit or loan amount) r = annual interest rate (APY) n = number of times that interest is compounded per year t = time the money is invested or borrowed for, in years

For this calculator, we assume interest is compounded quarterly (n = 4), which is typical for money market accounts.

Worked Example

Let's say you deposit $5,000 into a Capital One money market account with a 2.10% APY. You plan to keep the money in the account for 5 years.

Using the formula:

A = 5000 × (1 + 0.0210/4)^(4×5) A = 5000 × (1 + 0.00525)^20 A ≈ 5000 × 1.1166 A ≈ $5,583.00

After 5 years, your $5,000 deposit would grow to approximately $5,583, earning $583 in interest.

Frequently Asked Questions

What is a money market account?
A money market account is a type of savings account that offers higher interest rates than traditional savings accounts. These accounts are typically insured by the FDIC and are designed for short-term deposits.
What is APY?
APY stands for Annual Percentage Yield. It represents the actual yearly rate of return earned on an investment, taking into account the effect of compounding interest. APY is always higher than the stated annual interest rate (APR) because it accounts for compounding.
How often is interest compounded in money market accounts?
Interest in money market accounts is typically compounded quarterly, which means the interest is calculated and added to the account balance four times per year.
Can I withdraw money from a money market account anytime?
Most money market accounts allow you to withdraw funds at any time, but there may be restrictions on the number of withdrawals you can make in a month. It's important to review the terms and conditions of your specific account.
