Age 15Explain it to a 15-year-oldConnect it to the formula
The result is a mathematical hurdle rate, not evidence that the return is achievable at an acceptable risk. The rule is Required annual return = (target ÷ current value)^(1 ÷ years) − 1. Its input values are Current investment value, Target investment value, Years available, and the main result is Required compound annual return. Try changing one number and watch what happens to Required compound annual return.
CollegeExplain it at college levelState the model precisely
This calculator evaluates a personal-finance model from stated cash amounts, rates and time assumptions. The implemented relation is Required annual return = (target ÷ current value)^(1 ÷ years) − 1, evaluated from Current investment value, Target investment value, Years available to produce Required compound annual return. The result is a mathematical hurdle rate, not evidence that the return is achievable at an acceptable risk. The result cannot predict markets or include unentered taxes, fees, legal rules, benefits, insurance terms or personal circumstances. Verify material decisions against current documents.
