Two different calculations. Savings: growth of a lump sum — one principal, compound frequency, and term in years; no regular payments. Loan: repayment of a borrowed amount — fixed payment per period and a full amortization schedule (interest vs principal each period). Same interest maths, different use: saving vs borrowing.
