Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Loan Term Cost Comparison to answer this question: compare monthly payments and interest for shorter and longer terms on the same loan?

Age 15Explain it to a 15-year-oldConnect it to the formula
A longer term lowers the scheduled payment but normally raises lifetime interest when the rate and principal are unchanged. The rule is Interest for each term = monthly payment × months − principal. Its input values are Loan principal, Annual interest rate (%), Short term in months, Long term in months, and the main result is Extra interest from longer term. Try changing one number and watch what happens to Extra interest from longer term.
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 Interest for each term = monthly payment × months − principal, evaluated from Loan principal, Annual interest rate (%), Short term in months, Long term in months to produce Extra interest from longer term. A longer term lowers the scheduled payment but normally raises lifetime interest when the rate and principal are unchanged. The result cannot predict markets or include unentered taxes, fees, legal rules, benefits, insurance terms or personal circumstances. Verify material decisions against current documents.
