FV of Annuity DUe = ( 1 + r ) * FV of Annuity
FV of Annuity = (1+r) * CF [ (1+r)^n - 1 ] / r

Particulars | Amount |
FV of Annuity Due | $ 5,000,000.00 |
Int Rate | 7.000% |
Periods | 41 |
Cash Flow = [ FV of Annuity Due * r] / [ ( 1+ r) * [ [ ( 1 + r
)^n ] - 1 ] ]
= [ $5000000 * 0.07 ] / [ ( 1 + 0.07 ) * [ [ ( 1 + 0.07 ) ^ 41 ] -
1 ] ]
= [ $5000000 * 0.07 ] / [ ( 1.07 ) * [ [ (1.07 ) ^ 41 ] - 1 ]
]
= [ $350000 ] / [ ( 1.07 ) * [ [ 16.0227 ] - 1 ] ]
= [ $350000 ] / [ ( 1.07 ) * [ 15.0227 ] ]
= [ $350000 ] / [ 16.0743 ]
= $21773.95
Annual deposit required is $ 21773.95
