Why Pay Down?

The Hidden Cost of Minimum Payments

Credit cards compound interest daily. Minimum payments barely cover the interest charge itself, leaving your principal almost untouched. Most people never know what a $500 purchase really cost them after 18 months of carrying a balance — because no one ever shows them.

Every Dollar Accounted For

Pay Down's True Cost Engine uses FIFO allocation and day-by-day balance tracking to show exactly how much interest each individual purchase has accumulated. The actual math — FIFO allocation and daily balance tracking — applied to your real statement history, as precise as the data you import.

Pay Smarter, Not Harder

See which purchases to prioritize, track your payoff progress month by month, and celebrate every milestone with us. Knowing where your money is going is the first step to sending it somewhere better.

Features

Nine tools designed to do one thing — make the real cost of your credit card debt impossible to ignore, and then help you do something about it.

🧮

See what your purchases actually cost

That $500 dinner you charged in February didn't cost $500. After eight months of compounding interest, it cost roughly $568 — and your statement never broke it out. Pay Down breaks down every transaction on every card, applies daily-balance math across your billing cycles, and shows you what each purchase has really cost. Your real statements. Your real APRs. The actual cycle-by-cycle math, as precise as the data you import.

⚠️

The minimum payment trap, calculated

Paying $100/month on a $5,000 balance at 22% APR takes 14 years and costs $7,800 in interest. Most people never see that number. Pay Down does the math, then shows you what an extra $50 or $100 a month would actually save you — in years and in dollars.

🔄

Balance transfer calculator — fees and all

Every balance transfer offer hides three things: the transfer fee, what happens after the promo ends, and whether "0% APR" is true 0% or deferred interest that retroactively bills you if you don't pay it off in time. Pay Down models all three so you know before you sign.

HELOC & loan payoff calculator

A 9% loan looks great next to a 24% credit card — until you run the real numbers. Pay Down compares total interest, monthly payments, and time to payoff side by side, so you can decide whether consolidating is the smart move or just moving debt around.

📈

A plan that ends with you debt-free

Pay Down shows Avalanche and Snowball side by side — debt-free date, total interest, and first card paid off — using your average monthly purchases so the numbers match how you actually spend. When the difference is meaningful (at least $25 or one month), it's flagged. If new purchases are outpacing payments, you'll see a balance-growing warning. Prefer to cut spending instead? Reduce spending is right there too. Pick a plan, lock in a commitment, get weekly check-ins, and celebrate when a card hits zero.

Auto-sync, or stay in control

Connect your card via Plaid for automatic transaction tracking — or stick with free CSV imports from Chase, Amex, Capital One, Discover, and Citi. Either way, your data stays encrypted, biometric-locked, never sold, never shared.

📊

See the patterns your statement hides

Your true cost multiplier across every purchase. Category and merchant breakdowns ranked by interest paid. Your effective APR vs the rate printed on your card. Insights shows you the patterns a single statement can't — so you know where the interest is really going. Available with Premium.

💞

Finally, you're both looking at the same numbers

Managing debt with a partner shouldn't feel like guessing what the other person knows. Share any card and you both get full visibility — same transactions, same true cost, your own goals. No more "I thought you paid that" or one person carrying the whole mental load. Available with Premium.

The monthly check-in you keep meaning to do

You know you should sit down and review your spending. You also know you probably won't. Once a month, our AI does it for you and sends a short email with what actually matters — where interest crept up, what changed, whether you're on track. A gentle tap on the shoulder, included with Premium.
