Amortiza Loan Planner

概要

Plan paying off early: add a recurring extra payment or one-time lump sums and see the interest saved and how many months sooner the loan is paid off. Switch to biweekly or weekly payments, including accelerated biweekly. See the whole monthly housing payment (PITI): principal and interest, property tax, homeowners insurance, HOA dues and PMI. PMI is charged only while the loan is above 80% of the home value and drops off once the balance reaches 78%, with the dates shown. Compare 2 to 4 loans side by side, such as a 15-year vs a 30-year mortgage, different rates, or paying points to lower the rate. Each option shows the payment, total interest, upfront costs, total cost and the break-even month for points or fees. The interactive view has rate, term and extra-payment sliders, a balance and interest chart, a yearly table and a CSV download. Results are deterministic calculations from the numbers you give, the last payment is adjusted so the balance ends at exactly zero, and 0% loans are handled. No personal information is needed. Limitations: fixed-rate loans only (no adjustable-rate resets, interest-only or balloon loans); it does not look up current rates, taxes or insurance quotes; results are informational and are not financial advice.
