Understanding Required Returns

Required Rate: The annual return needed to reach your target from your starting point
Time Value of Money: Longer time horizons require lower rates to reach the same target
Risk-Return Tradeoff: Higher returns typically require accepting higher risk
Realistic Planning: Set achievable targets based on historical market returns

Required Rate (Discrete):

r = n * [(A/P)^(1/nt) - 1]

Required Rate (Continuous):

r = ln(A/P) / t

Where: A = Target, P = Principal, n = Frequency, t = Years
