About Tools Calculators
Compound interest, inflation and unit conversions are among the most commonly needed calculations in everyday financial planning. The compound interest calculator demonstrates the power of long-term investing — $10,000 invested at 7% for 30 years grows to over $76,000 without any additional contributions. With $200/month added, it reaches $262,000.
The inflation calculator uses official Australian Bureau of Statistics (ABS) Consumer Price Index data from 2000 to 2025. Average Australian inflation over this period has been approximately 2.8% per year, though notable spikes include 7.8% in 2022. At 3% inflation, $100 today is worth only $74 in 10 years.
Australia officially uses the metric system (kilometres, kilograms, Celsius) but imperial units remain common in everyday speech. Our unit converter handles length, weight, temperature, area, volume, and speed conversions between both systems. The percentage calculator covers the three most common percentage operations used in business and everyday life.
