How this comparison works
Every month, both plans pay the minimum on every debt. Your extra money is then split the way each plan says: part goes to paying down debt faster, the rest goes to savings. When a debt is paid off, its minimum payment rolls into the plan, so each payoff speeds up the next.
The avalanche method puts extra money on the highest interest rate first and usually costs the least. The snowball method clears the smallest balance first, which many people find easier to stick with. A starter emergency fund of $1,000 comes first if you tick that box, so a surprise bill doesn't go back on a card.
Net worth here means your savings minus what you still owe on these debts. The plan with the higher net worth after three years has done more for you in dollars, but the right plan is also the one you'll actually follow.
Questions
Should I pay off debt or save first?
For most people: build a small emergency fund first, then put extra money on any debt with a rate higher than your savings account pays. High-rate credit cards almost always win. Low-rate loans, like many car and student loans, are closer, and saving can make sense. This tool shows the difference in dollars for your own numbers.
