Difficulty: HardHire Purchase, Deferred Payment, and Credit Sale Schemes

A business owner acquires a piece of industrial equipment under a hire purchase agreement. The cash price of the equipment is 2,500,000₦2,500,000. The contract requires an initial deposit of 25%25\% of the cash price, with the remaining balance subject to simple interest of 12%12\% per annum calculated over a term of 22 years. If the principal balance and total interest are repaid in equal monthly installments over the 22-year period, what is the amount of each monthly installment in Naira?

Answer: 96875

Answer

The amount of each monthly installment is ₦96,875.
To determine the monthly installment in a hire purchase transaction, deducting the 25%25\% deposit (625,000₦625,000) from the cash price (2,500,000₦2,500,000) yields an unpaid balance of 1,875,000₦1,875,000. Applying 12%12\% per annum interest for 22 years yields total interest of 450,000₦450,000. Combining the balance and total interest gives 2,325,000₦2,325,000. Dividing this total by 2424 months yields 96,875₦96,875 per month.

Step-by-Step Solution

1
Calculate the initial cash deposit required
0.25×2,500,000=625,0000.25 \times ₦2,500,000 = ₦625,000
The buyer must pay 25% of the total cash price upfront.
2
Find the remaining unpaid principal balance
2,500,000625,000=1,875,000₦2,500,000 - ₦625,000 = ₦1,875,000
Interest is charged only on the balance remaining after paying the deposit.
3
Calculate the total simple interest accrued over 2 years
1,875,000×0.12×2=450,000₦1,875,000 \times 0.12 \times 2 = ₦450,000
Simple interest formula is I=P×R×TI = P \times R \times T where P=1,875,000P = ₦1,875,000, R=12%R = 12\%, and T=2T = 2 years.
4
Calculate the total sum to be spread across monthly installments
1,875,000+450,000=2,325,000₦1,875,000 + ₦450,000 = ₦2,325,000
The total installment debt consists of the outstanding principal balance plus the accrued interest.
5
Determine the value of each monthly installment
2,325,00024=96,875\frac{₦2,325,000}{24} = ₦96,875
A 2-year period comprises 24 equal monthly payments.
