Financial Calculators for Loans, Interest, Savings & Investments

Loan estimates depend on the amount borrowed, interest rate, term, and sometimes fees. Savings and investment projections depend on contribution timing and assumptions about growth. Use these tools to compare the numbers under different inputs rather than treat a projection as a guaranteed outcome.

How loan and savings calculations work

A mortgage payment can look manageable until you add property taxes, insurance, and fees that the principal-and-interest formula does not include. When comparing repayment terms, keep those extra costs separate and check how a longer term changes the total interest paid. The lowest monthly figure is not necessarily the least expensive way to borrow.

Savings projections need the same care. With compound interest, the starting balance, contribution dates, rate, and compounding frequency all affect the outcome. An assumed annual return is not a promise of future growth; compare several scenarios before using a projection in a budget.
