Age 15Explain it to a 15-year-oldConnect it to the formula
Deposit interest, legal protections, refund deductions and investment risk differ by jurisdiction and tenancy. The rule is Opportunity cost = deposit × [(1 + return)^years − 1]. Its input values are Rental deposit, Expected alternative annual return (%), Years deposit is held, Annual inflation rate (%), and the main result is Estimated investment growth forgone. Try changing one number and watch what happens to Estimated investment growth forgone.
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 Opportunity cost = deposit × [(1 + return)^years − 1], evaluated from Rental deposit, Expected alternative annual return (%), Years deposit is held, Annual inflation rate (%) to produce Estimated investment growth forgone. Deposit interest, legal protections, refund deductions and investment risk differ by jurisdiction and tenancy. The result cannot predict markets or include unentered taxes, fees, legal rules, benefits, insurance terms or personal circumstances. Verify material decisions against current documents.
