Formula Explained

The future value of a CD is calculated using the compound interest formula:

Future Value = Principal × (1 + (Rate ÷ Compounding Periods per Year) ^ (Compounding Periods per Year × Time in Years))

For this calculation:

Principal = $10,000
Rate = 1.65% (0.0165 as a decimal)
Compounding Periods per Year = 12 (monthly compounding)
Time in Years = 15 months ÷ 12 = 1.25 years

The formula accounts for monthly compounding, which means interest is added to the principal each month, leading to slightly higher returns than simple interest.

Worked Example

Let's calculate the future value of $10,000 invested at 1.65% annual interest for 15 months with monthly compounding:

Future Value = $10,000 × (1 + (0.0165 ÷ 12)) ^ (12 × 1.25) Future Value = $10,000 × (1 + 0.001375) ^ 15 Future Value = $10,000 × 1.0203 Future Value = $10,203.00

After 15 months, your $10,000 investment will grow to approximately $10,203, earning $203 in interest.
