Quick Formula Comparison

Simple Interest

I = P × r × t
A = P(1 + rt)

Use for: Short-term loans, hire purchase

Compound Interest

A = P(1 + i)n

Use for: Investments, savings, loans

Hire Purchase

P = Cash Price - Deposit
Monthly = Total ÷ months

Inflation/Population

Future = Present × (1 + rate)n

Same as: Compound growth

Complete Formula Summary

Topic Formula Variables
Simple Interest I = P × r × t P = principal, r = rate (decimal), t = time (years)
Accumulated Amount (Simple) A = P(1 + rt) A = total amount including interest
Compound Interest A = P(1 + i)n i = rate per period, n = number of periods
Hire Purchase Principal P = Cash Price - Deposit Deposit = % of cash price
Inflation/Population Future = Present × (1 + rate)n Same as compound growth

Quick Check: What do you know?
