Example #1

Mr. Tim, a Delaware resident, wants to buy a motorboat, which is costing around $35,000. On inquiry with the dealer, Mr. Tim got to know that he would also be liable to pay taxes, insurance on the same. The cost of insurance will be 5% of the cost, and taxes applicable would be 7% of the cost price. Since he doesn’t have that many funds in hand, hence decides to borrow a loan from the bank. The bank is financing him 90% of the total cost of the boat, and the rest will be paid by him upfront to the dealer. He chooses installment for 36 months equal installment. The Interest rate that the bank is charging is 10%, and there are 2% upfront processing charges on the sanctioned amount.

Based on the above information, you are required to calculate the monthly installment amount of the boat loan and calculate the total interest outflow.


We need to calculate the cost price of the boat.

Boat Loan Calculator Example 1

Now, we need the loan amount, which will be 39,200 *90%, which is 35,280.00. There is 2% of the Processing fees of the sanctioned loan amount, which will be paid upfront, which is $705.60. Lastly, the down payment by Mr. Tim will be 39,200 – 35,280.00, which is $3,920.00, which is 10% of the cost price

The loan period repayment is 24 equally installments, and further, the interest rate is 10.00% fixed, which shall be compounded monthly, which is 10.00%/12, which is 0.83%.

Boat Loan Calculator Example 1-1

Now we shall use the below formula to calculate the EMI amount.

EMI = (L * r *(1+r)n*F )/ ((1+r)n*F-1)
Boat Loan Calculator Example 1-2
  • = ($35,280.00 * 0.83% * (1 + 0.83%)^36 ) / ( (1 + 0.83%)^36 – 1 )
  • = $1,138.39

Therefore, the installment amount for Mr. Tim for next 3 years on the loan amount $35,280 shall be $1,138.39 and when multiplied same with 36 the total amount repaid will be $40,981.91 less $35,280.00 which equals to $5,701.91 and total cash outflow due to a loan will be $5,701.91 + $705.60 which is $6,407.51.

Example 1-3 (total interest)

Example #2

Mrs. Pooja is seeking to purchase a new boat and is looking the same to be financed by a bank. The total cost of the vehicle is $40,8000, which includes all. The Bank will grant a loan to the tune of 80%, and the rest will be repaid upfront by her. However, she is unsure as to what tenure she would choose as her goal is to keep her monthly cash outflow lower than $1,300 and, she is not ready to pay any cumulative interest amount throughout the loan period more than $8,000. The interest rate that the bank shall charge her will be 11.00%. The Bank can grant her repayment period either for 36 months or 48 months.

Based on the given information, you are required to advise Mrs. Pooja as to what should she do?


We need to calculate the installment amount that will be paid monthly basis; for that first, we need to know the amount of the loan, which is $40,800 * 80%, which is $32,640.00. The interest rate given is 11.00% fixed, and its compounded monthly that will be 11%/12, which is 0.92%.

Example 2 (Given data)

Now, using the below formula to calculate the installment amount for 36 months.

EMI = (L * r * (1+r)n*F) / ((1+r)n*F – 1) 
Boat Loan Calculator Example 2-1
  • = ($32,640 * 0.92% * (1 + 0.92%)^36) / ( (1 + 0.92%)^36 – 1 )
  • = $1,068.59

Total interest outflow will be equal to ($1,068.59 * 36) – $32,640 which is $5,829.30.

Example 2-2 (total interest)

Again, using the same formula, we will calculate the installment amount for 4 years, which is 48 months.

EMI = (L * r * (1+r)n*F) / ((1+r)n*F– 1)
Boat Loan Calculator Example 2-3
  • = ($32,640 * 0.92% *(1 + 0.92%)^48) / ( (1 + 0.92%)^48 – 1)
  • = $843.60

Total interest outgo equals to ($843.60 * 48) – $32,640 which is $7,852.70

Example 2-4 (total interest)

Advice: Since her preference is to not pay cumulative interest more than $8,000 in entire loan duration and for that, both are meeting her requirements and her second requirement is that installment amount should be lower and not more than $1,500 which only second option is preferable, and she should opt for 48 months.


Boat loans need to design in such a way that total outflow is not that big since the cost of the same is already huge. Boat involves a lot of expenses after acquiring them like fuel expenses, storage expenses, etc. and hence one should try to keep the finance costThe Finance CostFinancing costs refer to interest payments and other expenses incurred by the company for the operations and working management.
