Interest Formulas

Simple Interest

Linear Growth

Simple Interest = P × r × t

Calculated on the original principal only. Where P is principal, r is interest rate (as decimal), and t is time in years.

Variables

P
Principal amount
r
Annual interest rate (decimal)
t
Time in years

Compound Interest

Exponential Growth

A = P(1 + r/n)^(nt)

Compound interest is calculated on the initial principal and also on the accumulated interest from previous periods.

Variables

A
Total amount after interest
P
Principal amount
r
Annual interest rate (decimal)
n
Times compounded per year
t
Time in years

Practical Applications

Simple Interest Example

A student deposits R2,500 into a savings account that earns 4.5% simple interest per year. Calculate interest after 3 years.

1

P = R2,500, r = 4.5% = 0.045, t = 3 years

2

Interest = R2,500 × 0.045 × 3 = R337.50

Total balance: R2,500 + R337.50 = R2,837.50

Compound Interest Example

Invest R5,000 at 6% interest compounded annually for 4 years.

1

P = R5,000, r = 0.06, n = 1, t = 4 years

2

A = R5,000(1.06)^4 = R5,000 × 1.26248

Total amount: R6,312.40

Budgeting Example

Student earns R4,500 monthly. Expenses: rent R1,800, transport R600, cell R250, groceries R900, entertainment R400.

1

Total expenses: R3,950

2

Surplus: R4,500 - R3,950 = R550

Recommend saving R300 per month

Why Understanding Banking Matters

Saving Habits

Understanding interest helps maximize returns on savings. Compound interest allows savings to grow exponentially over time.

Start saving early to benefit from compound interest!

Borrowing Responsibly

Knowledge of loan terms helps compare options and understand true borrowing costs. Higher interest rates or longer terms significantly increase total repayment.

Always compare interest rates before taking a loan!

Budgeting Skills

The 50/30/20 rule: 50% for needs, 30% for wants, 20% for savings and debt repayment.

Track your spending to stay within budget!

Financial Planning

Setting specific, measurable financial goals increases the likelihood of achieving them. Banking knowledge forms the foundation for long-term financial planning.

Set SMART financial goals!
