Financial Awareness
Lesson 5 of 5
25 min
Keza is a mobile-money agent at a kiosk near the bus stop in Huye. Every morning she writes her opening cash in a notebook. Every time a customer deposits cash or withdraws it, she writes it down. Every evening she counts her cash and compares it with the book.
One Friday evening the box held Frw 5,000 less than the book said it should. Keza went through the day's entries one by one and found it: at the busy lunchtime a customer had withdrawn Frw 5,000 and, in the rush, she had not written it down. The money was not lost. Her record was incomplete. (An illustrative case.)
Think about it: Without the notebook, what might Keza have believed had happened to the money?
Whether you run a kiosk or manage your own pocket money, the same habits keep money under control.
| Habit | Why it matters |
|---|---|
| Keep written records of money in and money out | You can find mistakes and see where money goes |
| Make a budget and compare it with what actually happens (Lesson 1) | Overspending is caught early |
| Keep business and personal money apart | The business always has cash for stock and bills |
| Save first, and keep an emergency fund | A shock does not force you into debt |
| Borrow only for things that earn (Lesson 4) | Repayments come from new income |
| Check statements and mobile-money messages | Errors and fraud are spotted quickly |
| Protect your PIN and never share it | No one else can spend your money |
Definition
Financial records: written or digital notes of every amount of money received and paid out, with the date and the reason.
Example: Keza's notebook of deposits and withdrawals.
A cash record is checked with one formula:
Worked example
Checking Keza's cash for Friday (illustrative figures)
Opening cash: Frw 200,000. Cash received from customers' deposits: Frw 350,000. Cash paid out for withdrawals, as recorded: Frw 420,000.
Step 1: expected closing cash.
Step 2: compare. She counts Frw 125,000. Difference: .
Step 3: explain. A Frw 5,000 shortfall means Frw 5,000 went out without being recorded: the lunchtime withdrawal. Adding it gives recorded withdrawals of Frw 425,000, and , which matches the cash.
Banks give customers plastic cards for paying in shops and online and for taking cash from machines. Two cards can look identical and work in completely different ways.

Definition
Debit card: a card that takes money straight from your own bank account when you pay or withdraw cash. You can spend only what is in the account.
Example: Aline pays for groceries with her debit card, and Frw 12,000 leaves her account at once.
Definition
Credit card: a card that lets you spend the bank's money, up to a limit, and pay it back later. If you do not repay the full amount by the due date, the bank charges interest on what is left.
Example: a business owner buys a Frw 300,000 laptop with a credit card and repays the bank over the following months.
Definition
Credit limit: the most a credit-card holder may owe the bank at one time. PIN (personal identification number): the secret code that proves you are the card's owner. ATM (automated teller machine): a machine that gives out cash when you insert a card and enter your PIN.
Example: a credit limit of Frw 500,000; a four-digit PIN.
| Debit card | Credit card | |
|---|---|---|
| Whose money do you spend? | Your own, from your account | The bank's: a short-term loan |
| When is it paid? | Immediately | Later, when the monthly bill arrives |
| How much can you spend? | What is in your account | Up to the credit limit |
| Interest | None on purchases | Charged if the bill is not paid in full |
| Main benefits | No debt; safer than carrying cash; a record of every payment | Pay for large or urgent items before you have the cash; accepted abroad and online |
| Main risks | Fees; theft of the card and PIN; card details stolen online | Easy to overspend; high interest; debt that grows; the same theft risks |
A mobile-money wallet works much like a debit card: you can spend only the money in it, and each payment leaves a message as a record.
Worked example
What an unpaid credit-card bill costs (illustrative rate)
Suppose a credit card charges 3% a month on any balance not repaid, and Frw 80,000 is left unpaid.
Interest for one month:
Over 12 months (even if the interest itself were never charged interest):
At least Frw 28,800 a year for nothing but delay. In practice it is more, because unpaid interest is added to the balance.
Worked example
Small fees add up (illustrative fee)
Suppose each cash withdrawal costs a fee of Frw 300. Mugisha withdraws cash 8 times a month.
If he plans ahead and withdraws once a week (4 times a month): , a saving of Frw 14,400 a year.
Warning
Keep your PIN secret, always. No bank, SACCO or mobile-money company will ever ask for your PIN by phone or message. Cover the keypad at an ATM, never let anyone "help" you with the machine, and report a lost card at once so it can be blocked.
Tip
Treat a credit card like a debit card. Spend on it only what you already have in the bank, and repay the whole bill every month. Then the card is a convenience and never a debt.
Learn Bright, "Financial Literacy: Debit and Credit" (about 5 minutes). Watch for when each card is the better choice. The video is American, so the fees and rules differ in Rwanda; the principles are the same.
