Which personal finance & loans tool should I use?
Pay a debt off sooner
Compare the existing schedule with extra principal payments. Check whether your lender applies payments immediately, charges a prepayment fee, or uses a different interest method.
Compare growth scenarios
Use compound interest to explore rates, contributions and time. A fixed assumed return is a scenario, not a forecast or guaranteed investment result.
Compare borrowing or income
Keep loan fees and payment frequency consistent when comparing offers. Salary conversions do not automatically account for local deductions or tax.
