How This Calculation Works
The calculator uses the compound interest formula:
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 this 2.00% APY 18-month term account, we use:
- Annual interest rate (r) = 2.00% or 0.02
- Term length (t) = 18 months or 1.5 years
- Compounding frequency (n) = 12 (monthly) or 4 (quarterly)
Worked Example
Let's calculate the growth of $1,000 over 18 months with monthly compounding:
| Step | Calculation | Result |
|---|---|---|
| 1 | Principal (P) | $1,000.00 |
| 2 | Monthly rate (r/n) | 0.02/12 = 0.0016667 |
| 3 | Number of periods (nt) | 12 × 1.5 = 18 |
| 4 | Final amount (A) | $1,000 × (1 + 0.0016667)^18 ≈ $1,030.48 |
| 5 | Interest earned | $30.48 |
After 18 months, your $1,000 investment would grow to approximately $1,030.48 with monthly compounding.
