Correct calculations

NPV = -1,000,000/(1 + 10.38%)¹- 3,000,000/(1 + 10.38%)²- (750,000/10.38%) / (1 + 10.38%)³

= - $905,961.22 - $2,462,297.22 - $7,225,433.53/(1 + 10.38%)³

= - $905,961.22 - $2,462,297.22 - $5,372,701.85

NPV = $8,740,960.30

I compared my Excel function to the above results... I'm getting NPV= -$8,738,535.38 and not the NPV =$8,740,960.30 as noted on the equation above. Can you share the Excel function inputs that need be enter to calculate NPV for the above equation? I would like to compare it to my entries for a better understanding? Thank you!
