1) Max Yield denoted as i_{max}

2) Min Yield denoted as i_{min}

3) Constant Ratio denoted as i_{cr}

4) Direct Ratio denoted as i_{dr}

This calculator has 4 inputs.

1) Max Yield denoted as i

2) Min Yield denoted as i

3) Constant Ratio denoted as i

4) Direct Ratio denoted as i

This calculator has 4 inputs.

v = 1/(1 + APR)

i_{mxy} = (2 * m * k)/(L * (n + 1) - k * (n - 1))

i_{mny} = (2 * m * k)/(L * (n + 1) + k * (n - 1))

i_{cr} = 2 * m * k/L * (n + 1)

i_{cr} = 2 * m * k/(L * (n + 1) - 1/3 * k * (n - 1))
