Why Minimum Payments Keep You in Debt (With the Math)
Paying the minimum feels responsible — you're paying, after all. But minimum payments are engineered to keep a balance alive for years, quietly draining you in interest. Once you see the math, you can't unsee it.
How a minimum payment is calculated
On most credit cards, the minimum is a tiny percentage of the balance (often 1–3%) plus that month's interest, with a small floor like $25–$35. Because it's a percentage of the balance, the minimum shrinks as the balance shrinks — so your payments get smaller right when you'd want them bigger, stretching the payoff over many years.
Where your money actually goes
Say you owe $3,400 at 23.99% APR. One month's interest is roughly balance × APR ÷ 12 ≈ $68. If your minimum is around $85, only about $17 actually reduces the balance — the rest is just rent on the debt. Next month the balance barely moved, so it happens again. That's the trap: most of each minimum payment is interest, so the principal crawls.
The fix: a fixed extra, every month
Instead of a shrinking percentage, pay a fixed amount that stays the same as the balance falls. Even a modest fixed extra dramatically shortens the payoff, because more of every payment attacks principal. Then, when one debt is gone, roll its whole payment onto the next — the snowball effect.
See your own interest total
The scary number isn't the balance — it's the total interest you'll pay on your current plan. Dollar Debt Plan shows you that number, then shows how much it shrinks when you add extra and pick a smarter payoff order. Related reading: snowball vs. avalanche vs. cash-flow.

Is paying the minimum bad for my credit? No — paying the minimum on time keeps your account current. The problem is cost and time, not your score.
How much extra should I add? As much as your surplus allows, paid as a fixed amount. Even small fixed extras beat the shrinking minimum.
