About this generator

Understanding interest is everyday maths. The sheets start with interest after one year, move on to compound interest where the growth factor is used several times, and explain the difference between percent and percentage points when an interest rate changes. Answers are rounded to two decimals in the local currency. The answer key is calculated by the website, so it always matches the tasks. No sign-up is needed and no personal data is collected.

  • Revision before a test

Plan a useful printable

Start with one clear learning goal and choose only the settings that support it. A short, focused sheet is often easier to explain, complete and review than a crowded page. The live preview makes it possible to check spacing, task count and difficulty before paper is used. Create another version when a class needs the same skill with different content.

Adapt it to the learner

Use fewer items, larger writing areas and familiar content for beginners. Increase the amount, range or complexity gradually for confident learners. Teachers can also combine the printable with oral instructions, pair work or a short follow-up discussion. Because every page is customizable, the same activity can support a warm-up, independent practice, homework or revision.

Print clearly and reuse

Choose A4 or US Letter to match the printer, then print at 100 percent whenever exact spacing matters. The PDF option uses the browser print dialog and creates a clean file for later use. Generated content is prepared in the browser, requires no pupil account and has no watermark. Review every sheet before sharing it, especially when you add your own words or text.

What is compound interest?
Interest is added to the balance, so next year you earn interest on the interest: value = start × (1 + p/100)ⁿ.
What is a percentage point?
The difference between two percentages: from 2 % to 3 % is 1 percentage point.
