Why $50 extra a month changes everything

Treedy TeamMoney tips

Small extra payments don't feel like much. On a credit card, they can cut years and thousands of dollars.

The same card, three ways

Here's a $5,000 card balance at 24% APR with a fixed $150 monthly payment, and what happens when you add a little on top.

PlanPer monthPaid off inInterest
Payment only$15056 months$3,322
+ $50 extra$20036 months$2,001
+ round-ups (about $15/week)$21532 months$1,794

Fixed payments, 24% APR compounded monthly. Your card's actual terms will differ.

Why it works so well

Every extra dollar skips the interest line and goes straight to your balance. A smaller balance means less interest next month, so more of your regular payment reaches the balance too. The effect compounds in your favor.

Where to find the extra

  • A subscription you forgot about (the average is more than you'd guess).
  • Rounding every purchase up to the next dollar.
  • Half of any raise, refund or side income, sent straight to the card.
Rule of thumb

On a high-interest card, every extra $1 you pay today is worth more than $1 later, because it stops interest from growing on it.
