Struct FutureValue

pub struct FutureValue {
    pub cash_flow: f64,
    pub interest_rate: f64,
    pub time_periods: f64,
}

Expand description

Calculates the future value of a cash flow received today

§Example

use com_croftsoft_core::math::finance_lib::FutureValue;
assert_eq!(
  FutureValue {
    cash_flow:     1.0,  // Investing $1 today
    interest_rate: 0.12, // At 12% per year
    time_periods:  6.0,  // For six years with interest compounded annually
  }.calculate(),
  1.973_822_685_184_001); // Will double your money (see the "Rule of 72")

Fields§

§cash_flow: f64

Cash flow invested or received today

§interest_rate: f64

Interest, discount, or inflation rate (use 0.01 for 1%)

§time_periods: f64

Number of periods from today when the value is evaluated
