The $200 Experiment: How One Extra Payment Per Month Changes Everything

The Setup

Scenario: $25,000 across three debts. Minimum monthly payments total $620. You have $200/month you could put toward extra payments. Should you bother?

Let's see exactly what that $200 does.

The Math, Debt by Debt

Debt A: $8,000 credit card at 22% APR — min payment $200/month

Debt B: $12,000 personal loan at 14% APR — min payment $280/month

Debt C: $5,000 medical debt at 9% APR — min payment $140/month

Without the extra $200:

With $200 extra directed to Debt A (highest APR first):

The extra $200/month saves $4,050 in interest and 20 months.

The Avalanche Sequence in Action

Here's what the timeline actually looks like:

Months 1–11: Extra $200 attacks Debt A. Debt A eliminated.

Months 12–28: Free up $400/month ($200 extra + Debt A's minimum). Combined attack on Debt B.

Months 29–38: Full $680/month ($400 + Debt B's minimum) toward Debt C. Done.

This is the "debt roll" — as each debt falls, its minimum payment rolls into the next target. The acceleration builds on itself.

Where Does $200 Come From?

We ran a survey of our users who successfully found extra payment money. The most common sources:

Finding $200/month doesn't usually require a dramatic lifestyle change. It requires noticing where it's currently going.

The Ceiling Effect

Once you've established the habit of extra payments, scaling up becomes psychologically easier. Users who start with $100 extra typically increase to $200–$300 within 6 months as they see the payoff date moving closer.

Use DebtMirror's payoff simulator to see your exact payoff date and interest savings at any extra payment amount. Watching the date move backwards is more motivating than any budgeting advice.

The $200 Rule

If you can only do one thing today: find $200/month in your budget and point it at your highest-APR debt. Not your biggest debt. Not your smallest debt. Your most expensive debt.

The math compounds in your favor from day one.
