Using the Calculator

Our calculator estimates your potential earnings from a Vanguard Cash Plus account. Simply enter your account balance and the current interest rate, then click "Calculate" to see your estimated earnings.

The calculator assumes:

Interest is compounded quarterly
No withdrawals during the period
The interest rate remains constant

Formula Explained

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 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 Vanguard Cash Plus, we use n=4 (quarterly compounding) and t=1 (one year).

Worked Example

Suppose you have $5,000 in your Vanguard Cash Plus account with an annual interest rate of 2.5%.

Using the formula:

A = 5000 × (1 + 0.025/4)^(4×1) A = 5000 × (1.00625)^4 A ≈ 5000 × 1.0253 A ≈ $5,126.50

After one year, you would earn approximately $126.50 in interest.
