Motorcycle Loan Refinance Calculator with Bi-Weekly Payments

This calculator compares your current motorcycle loan to a potential refinance, supporting monthly and bi‑weekly payment schedules. It estimates periodic payments, total interest costs, approximate payoff times, interest savings, and months to recoup refinance fees.

Results are estimates for planning only. They rely on standard amortization math and assume fixed APR, regular on‑time payments, and that any listed fees are paid at refinance closing or added to the loan amount as entered.

Methodology

We compute periodic payments using the standard amortization formula: Payment = P * r / (1 - (1 + r)^-n), where r is the periodic interest rate and n is the number of periods.

Bi‑weekly schedules use 26 periods per year. Making bi‑weekly payments often results in the equivalent of 13 monthly payments per year, accelerating principal reduction; the tool reports monthly equivalents to help compare cash flows.

Break‑even months = refinance fees divided by the monthly cash savings (monthly equivalent) between current and refinance loans. If monthly savings are zero or negative, break‑even is not meaningful.

Key takeaways

Use the calculator to compare estimated cash flow, total cost, and break‑even timing when refinancing a motorcycle loan. It highlights the acceleration effect of bi‑weekly payments and shows both periodic and monthly‑equivalent payments for easy comparison.

Always confirm final terms, fees, and payoff amounts with a lender. Small rounding differences and assumptions (e.g., payment timing, day count conventions) affect exact totals.

Worked examples

If your current loan balance is $5,000 at 6.5% with 36 months remaining (monthly), and you refinance $5,000 at 4.5% for 3 years with $250 fees and choose bi‑weekly payments, the calculator will show periodic bi‑weekly payments, monthly equivalent payments for easy comparison, total interest over each path, and months to recoup the $250 fee.

Bi‑weekly example: A bi‑weekly schedule with 26 payments per year yields a monthly equivalent equal to periodic payment × 26 / 12; over a year this typically equals 13 standard monthly payments.

F.A.Q.

Does switching to bi‑weekly always save interest?

Not always. Bi‑weekly schedules can reduce interest because they increase the number of payments per year relative to a monthly plan (26 vs 12), effectively adding one extra monthly payment per year. Savings depend on APR, remaining balance, term, and whether the lender applies payments immediately to principal.

What is APR versus interest rate?

APR reflects the annual cost of borrowing, including certain fees depending on disclosure rules; the periodic interest rate used in amortization is APR divided by the number of periods per year. Always check how your lender defines and applies fees and APR.

How is break‑even calculated?

Break‑even months = refinance fees / monthly savings (monthly equivalent current payment minus monthly equivalent refinance payment). If monthly savings are less than or equal to zero, the refinance does not recoup fees in this simple calculation.

Are these numbers exact for my payoff?

No. These are estimates calculated using standard amortization formulas. Exact payoff amounts depend on your lender's amortization schedule, how extra/partial payments are applied, timing of payments, and any prepayment penalties. Use lender payoff quotes for final figures.

Should I include fees in the refinance amount or pay them upfront?

This calculator treats refinance fees as one‑time costs entered separately and adds them to the total cost. If you roll fees into the loan amount, increase the refinance loan amount accordingly; that will raise periodic payments and change total interest.
