How this is calculated
A = P × (1 + r/n)^(n×t), where n is the number of compounding periods per year

Assumptions used in this calculation

  • Compounding frequency: Choose the frequency that matches your investment, more frequent compounding produces a higher maturity value for the same stated annual rate.
