Answer: a) $1,000 + $1,000 x .08 x 3 = $1,240
Explanation:
Monthly retirement Benefit at age 67 = $1000
Incremental rate on benefit beyond age 67 = 8%
Incremental rate on benefit beyond age 70 = 0
Period = 70 - 67 = 3years
Estimated monthly benefit at age 72;
Monthly benefit at age 67 + (monthly benefit at age 67) × incremental rate × increment period × 12
$1000 + ($1000 × 0.08 × 3 )
$1000 + $240.00
=$1240
Similarly,
This means monthly rate = 8% / 12 = 0.0066667
Total period = 12 × 3 = 36 months
Total = Principal + (principal × rate × time)
1000 + (1000 × 0.0066667 × 36)
1000 + 240.0012
1,240.0012 = 1240
