The avalanche method saves more money mathematically, while snowball provides better motivation. Choose the strategy you'll stick with consistently.
How much should I save for retirement?
Financial experts recommend saving 10-15% of your income for retirement. Use our retirement calculator to determine if you're on track. The rule of thumb is to have 1x your salary saved by age 30, 3x by 40, 6x by 50, and 10x by retirement age.
