Tally

Free to use; interest on Tally line of credit

Best for automating credit card debt repayment

Tally takes a different approach: it issues you a lower-interest line of credit and uses it to pay your cards optimally. You just make one payment to Tally. It's clever, though you are technically taking on new debt to pay off old debt.

Pros

  • Automates optimal credit card payments
  • Lower interest rate through Tally line of credit
  • Late fee protection

Cons

  • Requires good credit to qualify
  • Only handles credit card debt — not loans
  • You are taking on new debt to pay old debt

Cons

  • No payoff strategy calculator
  • $14.99/month while you are trying to save money

Frequently asked questions

Fact-checked answers pulled from the corresponding category research.

What is the difference between avalanche and snowball debt payoff?

Avalanche targets the highest-interest debt first, saving you the most money overall. Snowball targets the smallest balance first, giving you quick wins that keep you motivated. Avalanche is better on paper. Snowball has higher completion rates in practice. Pick whichever one you'll actually stick with.

Should I pay off debt or invest?

Rule of thumb: pay off high-interest debt (above 7%) before investing beyond your employer match. For low-interest debt like mortgages or federal student loans under 5%, investing usually wins long-term. But always contribute enough to get your full 401(k) match first—that's a guaranteed 100% return.
