What to Focus On

  • Instalment buying is used for costly goods.
  • A partial payment is made first.
  • The balance is paid later in instalments.

  • Cash Price means full outright payment.
  • Cash Down Payment means partial upfront payment.
  • Instalment means regular later payment.

  • Monthly instalment plans use simple interest.
  • Interest paid = Total amount paid − Cash price.
  • Total principal is the sum of monthly balances.

Common Mistakes to Avoid

Interest under the instalment plan is found by subtracting the cash down payment from the total of instalments.

Monthly instalment problems always use compound interest.

For monthly instalments, the full annual rate is used directly in the simple interest formula without dividing by 12.
