The debt avalanche method prioritises paying off the highest-interest debt first, minimising total interest paid. The debt snowball method pays off the smallest balance first regardless of interest rate, providing psychological wins to maintain motivation. Mathematically, the avalanche saves more money. However, research shows many people are more successful with the snowball method because the early wins keep them engaged.

Financial advisers commonly suggest saving 20% of your take-home pay (the 50/30/20 rule: 50% needs, 30% wants, 20% savings). However, the 'right' rate depends on your goals, age, and existing savings. For retirement, many advisers suggest saving half your age as a percentage, so a 30-year-old should save 15% of income for retirement. Even saving £50/month consistently makes a meaningful difference over time.

Compound interest means you earn interest on your original deposit plus all previously earned interest. With £10,000 at 4% annual interest: Year 1 = £10,400; Year 2 = £10,816 (interest on £10,400, not £10,000); Year 10 = £14,802. The more frequently interest is compounded (monthly vs annually), the faster growth accelerates. Einstein reportedly called compound interest 'the eighth wonder of the world'.
