Accuracy Notes
Every Contract NPV Calculator on CalcIntel uses a documented formula. Results are estimates, real outcomes depend on assumptions and market conditions not captured in a simplified calculation.
Formula
Compound growth follows:
A = P(1 + r/n)^(nt) + PMT × ((1 + r/n)^(nt) − 1) / (r/n)
Where P is the starting balance, r the annual rate, n the compounding periods per year, t the years, and PMT any recurring contribution. The second term captures the future value of regular deposits.
Worked Example
$100k initial, $25k/yr × 5 yrs at 8%
- initial
- 100000
- cashflow
- 25000
- rate
- 8
- periods
- 5
- Result
- −$185 (slightly negative)
Sum of discounted cash flows = $99,815, minus $100,000 initial = −$185. Marginally rejected.
