Role-play taking out a small pretend loan using play money, create a repayment plan, calculate simple interest, and track payments on paper.


Step-by-step guide to role-play taking a small pretend loan using play money, create a repayment plan, calculate simple interest, and track payments on paper
Step 1
Pick a pretend thing you want to buy with your loan like a bike a game or a craft kit.
Step 2
Choose how much pretend money you will borrow and write that number on your paper as the loan principal.
Step 3
Choose an interest rate per year (pick a percentage like 5% or 10%) and write that percentage on your paper.
Step 4
Choose how many years you will take to repay the loan and write that number on your paper.
Step 5
Convert the interest rate into a decimal and calculate the total simple interest using I = P × r × t then write the interest amount on your paper.
Step 6
Add the interest amount to the principal to find the total amount to repay and write the total repayment amount on your paper.
Step 7
Decide how many payments you will make (for example how many months) and write that number on your paper.
Step 8
Divide the total repayment by the number of payments to calculate each payment amount and write the payment amount on your paper.
Step 9
Draw a payment tracker table on your paper with columns for payment number due date payment amount amount paid and remaining balance.
Step 10
Take the play money equal to the principal to represent the loan and record "Loan received" and the starting balance in your payment tracker.
Step 11
Make a payment using play money then record that payment and subtract it from the remaining balance on your tracker.
Step 12
Share your finished loan plan payment tracker and what you learned on DIY.org.

What can we use if we don't have play money or a calculator?
If you don't have play money, use real coins or cut paper into pretend bills and still 'take the play money equal to the principal', and use a smartphone or basic calculator to do the I = P × r × t calculation.
What should we do if we get the interest or payment amount wrong?
If the numbers don't add up, re-check the 'Convert the interest rate into a decimal' step (divide the percent by 100), recompute I = P × r × t, add the interest to the principal to find the total repayment, and then re-divide by the number of payments.
How can we change the activity for different ages?
For younger kids, pick a small whole-number principal, a round interest rate, a one-year term, and count payments with play money on a big drawn payment tracker, while older kids can use monthly payments, exact decimals, due-date columns, and try compound interest or a spreadsheet for more challenge.
How can we make the loan activity more interesting or educational?
Have the child write a mock loan contract, try making extra payments to watch the 'remaining balance' drop on the payment tracker, add rules like late fees, and decorate the tracker before sharing the finished loan plan on DIY.org.

Facts about loans and simple interest for kids
📆 A repayment schedule shows each payment date and how much goes to interest versus how much pays down the loan balance.
🧾 Making extra payments on a loan can shrink the principal faster and reduce the total interest you pay.
💰 Simple interest is calculated with I = P × R × T (interest = principal × rate × time).
📝 Tracking payments on paper is a great way to practice budgeting and see progress as the loan gets paid off.
🕒 With simple interest you only pay interest on the original loan amount—not on interest that has already accrued.
