Past performance does not guarantee future returns. Actual investment results depend on market conditions, fees, and the specific investments chosen. Starting early and investing consistently tends to produce the best long-term outcomes due to the compounding effect.
Below is the step-by-step calculation used to determine the result.
Answer
$182,946.04
FV = $1,000 × [((1 + 8%/12)^120 − 1) / (8%/12)] = $182,946.04
Monthly contribution
$1,000 for 10 years (120 payments)
Total contributed
$1,000 × 120 months = $120,000.00
Future value
$182,946.04 ($62,946.04 in interest earned)
Step-by-Step Solution
Monthly contribution: $1,000 for 10 years (120 payments)
Total contributed: $1,000 × 120 months = $120,000.00
Apply monthly compounding at 8%/12 = 0.006667 per month
Future value: $182,946.04 ($62,946.04 in interest earned)
