Step-by-step solution

  1. Find the sales tax. Here it's charged on the full price of the motorcycle

    $14,000.00×7%=$980.00

  2. Find how much you borrow: the price, minus your down payment and trade-in, plus the tax

    $14,000.00−$1,500.00−$1,000.00+$980.00=$12,480.00

  3. Divide the yearly rate by 12 to get the monthly rate, because interest is charged every month

    i=0.08912=0.00741667

  4. Find the monthly payment. A standard formula gives the one amount that pays off the loan, with interest, in 48 months

    $12,480.00×0.007416671−(1+0.00741667)−48=$309.97

  5. Find the total interest: all your payments added up, minus what you borrowed

    $309.97×48−$12,480.00=$2,398.71

  6. Find the total cost of the motorcycle: the price, the tax and the interest

    $14,000.00+$980.00+$2,398.71=$17,378.71

  7. Add your gear to the cash you pay at the start

    $1,500.00+$1,200.00=$2,700.00

  8. Add one month of insurance to the loan payment

    $309.97+$600.0012=$359.97

  9. Add a year of loan payments and insurance. You pay both even in months the bike stays parked

    $309.97×12+$600.00=$4,319.68

  10. Divide by the months you ride to see what each riding month really costs

    $4,319.688=$539.96

  11. Add the cash at the start to find what you spend in the first year

    $2,700.00+$4,319.68=$7,019.68

What this calculator does

Find out what a motorcycle will cost you each month, and how much cash you need to get riding. Enter the price, your down payment, any trade-in, the sales tax, the interest rate and the loan length. You'll see your monthly payment, how much you're borrowing, the total interest and the total cost. A table shows the loan year by year.

A bike has costs that a car loan page won't show you. You need a helmet and riding gear before you leave the lot, so this calculator adds that to your cash at the start. Many riders also park the bike for part of the year, but the payment and insurance don't stop. Enter the months you ride, and you'll see what each riding month really costs.

Where it's used

Why this math matters outside the classroom:

  • Monthly bike payment. A rider financing $12,480 at 8.9% for 48 months finds a payment of about $309.97 a month.
  • Comparing loan lengths. The same $12,480 over 36 months costs about $396.28 a month but saves about $613 of interest.
  • First-bike budget. A new rider adds a $1,500 down payment to $1,200 of gear and sees that $2,700 is needed at the start.
  • Seasonal riding. A rider divides $4,319.68 of yearly payments and insurance by 8 riding months to get about $539.96 each.
  • Classroom finance. Students use the geometric series formula to find the equal payment that clears a loan over 48 months.

How to use it

  1. Enter the motorcycle's price, your down payment and any trade-in value.
  2. Enter your sales tax rate. Choose what it's charged on, and whether it goes into the loan or gets paid up front.
  3. Enter the APR and the loan length in months or years. You can go up to 84 months.
  4. Enter your yearly insurance, your gear budget and the months you ride each year. Then read your payment, your cash at the start and your cost per riding month.

What the inputs mean

Trade-in value
What you'd get for your current bike, after paying off any loan on it. Leave it at 0 if you aren't trading one in.
Sales tax rate
Your combined state and local rate. Rules differ from place to place, so check where you'll register the bike.
Sales tax is charged on
Some places tax the price minus your trade-in. Others tax the full price. Pick the one that matches where you live.
Interest rate (APR)
The loan's yearly interest rate (APR stands for annual percentage rate). Use the rate you've actually been quoted.
Loan term
Up to 7 years (84 months).
Insurance per year
Get a real quote before you buy. It can change a lot with the bike, your age, your record and where you live.
Riding gear
Your helmet, jacket, gloves, boots and anything else you need. The calculator treats this as cash at the start, not part of the loan.
Months you ride each year
Use 12 if you ride all year. Use fewer if the bike sits through the winter.

Formula and method

sales tax = tax rate × (price, or price − trade-in)
amount financed = price − down payment − trade-in (+ tax if rolled in)
i = APR ÷ 12;  payment = P × i ÷ (1 − (1 + i)^(−n))
total cost = price + sales tax + (payment × n − P)
cash at the start = down payment + gear (+ tax if paid up front)
cost per riding month = (payment × 12 + insurance) ÷ riding months
first-year spending = cash at the start + payment × 12 + insurance

In the formulas, P is the amount financed (what you borrow), i is the monthly interest rate and n is the number of monthly payments. The payment formula is the same one used for car loans and mortgages. It finds the one monthly amount that pays off the loan, with interest, in exactly n months. At 0% APR, the payment is P ÷ n.

Cost per riding month takes a full year of loan payments and insurance, then divides by the months you ride. You pay both all year, so the months the bike is parked get folded into the months you use it. Gear is left out here, because you buy it once. On a loan shorter than a year, only the payments you actually make are counted.

First-year spending is the most cash the bike is likely to take from you in any one year. It includes everything you pay at the start.

Worked example

A $14,000 motorcycle with $1,500 down and a $1,000 trade-in. Sales tax is 7% on the full price, rolled into the loan, at 8.9% APR for 48 months. Insurance is $600 a year, gear is $1,200 and you ride 8 months a year.

  1. Sales tax: $14,000 × 7% = $980.
  2. Amount financed: $14,000 − $1,500 − $1,000 + $980 = $12,480.
  3. Monthly rate: 0.089 ÷ 12 ≈ 0.00741667.
  4. Payment: $12,480 × 0.00741667 ÷ (1 − 1.00741667^(−48)) ≈ $309.97.
  5. Total interest: $309.97 × 48 − $12,480 ≈ $2,398.71.
  6. Cash at the start: $1,500 + $1,200 = $2,700.
  7. A year of payments and insurance: $309.97 × 12 + $600 ≈ $4,319.68.
  8. Cost per riding month: $4,319.68 ÷ 8 ≈ $539.96.

Result: The loan payment is about $309.97 a month, or $359.97 with insurance. You need $2,700 at the start, and each riding month costs about $539.96. Price, tax and interest together come to about $17,378.71.

Understanding the result

Look at the monthly payment with insurance first. That's the amount leaving your account every month, in riding season or not.

The cost per riding month shows the real price of a short season. In the example, riding 8 months makes each one cost about $539.96. Riding all 12 would bring it down to about $359.97.

A longer loan lowers the payment but raises the total interest. At 60 months instead of 48, the example's payment falls to about $258.46. But the interest grows by about $628.83. At 36 months, the payment rises to about $396.28 and the interest falls to about $1,786.08.

Assumptions and limitations

  • The APR stays the same for the whole loan, and you make equal payments at the end of each month.
  • Gear is paid once, in cash, at the start. Insurance stays the same each year.
  • In a short final year, the table counts only that part of the year's insurance.
  • Sales tax uses the one rate you enter. Payments aren't rounded to the cent, so a lender's final payment may differ by a few cents.
  • This doesn't include fuel, tires, servicing, registration or dealer fees. Add dealer fees to the price if you want them in the loan.
  • Some insurers offer a lower rate for months in storage. If yours does, enter the yearly amount you'd really pay.
  • Rates and terms depend on you, the lender and the bike. The results are estimates, not a loan offer.

Frequently asked questions

How long should a motorcycle loan be?

That depends on your budget, but shorter is cheaper overall. Try a few lengths and compare the payment with the total interest. Keep in mind how long you expect to keep the bike, because you'll need to clear the balance if you sell.

Can I roll my gear into the loan?

This calculator treats gear as cash at the start. If a dealer lets you add it to the loan, add the cost to the price instead and enter 0 for gear. You'll then pay interest on it, and sales tax in this calculator too.

Why count the months I don't ride?

Because the payment is due in those months anyway. The cost per riding month doesn't change what you owe. It only shows what you're paying for each month you actually get to ride.

Does my trade-in lower the sales tax?

In some places it does, because tax is charged on the price minus the trade-in. In others, tax is charged on the full price. Choose the option that matches where you'll register the bike, and check with your local tax office.

What if I owe money on my trade-in?

Enter only what you'd keep after that loan is paid off. For example, a $3,000 trade-in with $2,000 still owed counts as $1,000 here. If you owe more than it's worth, enter 0 and add the shortfall to the price.
