Compound Interest - Commbank

Commonwealth Bank (CommBank) is Australia’s largest retail bank, providing a variety of financial services to millions of customers. The bank partnered with Ernst & Young and engaged Punchy Studio to create an educational video to address the communication challenge of explaining complex financial concepts like interest and compound interest to a younger audience. The brief was to simplify how interest works both as a reward for saving and a cost for borrowing, while highlighting the exponential power of compounding over time. We produced an engaging animated explainer video that uses relatable scenarios and clear visual growth metaphors to illustrate how money can earn interest on interest. Our approach focused on practical financial literacy, providing viewers with simple rules of thumb such as seeking high interest rates for savings and low rates for debt. The video is deployed across CommBank educational platforms and community outreach programs to empower the next generation with essential money management skills. By combining professional scripting, custom animation, and a friendly, accessible voiceover, we turned a technical subject into an easy to understand guide. Dynamic motion graphics reinforce the key message that the impact of interest grows over time, encouraging viewers to start their savings journey early and consult with trusted adults about financial decisions.
