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
$10,000 invested at 7.0% for 20 years with no further contributions.
- Principal
- $10,000
- Annual rate
- 7.0%
- Years
- 20
- Result
- $38,697
The investment earns about $28,697 in compound interest.
