Methodology & Sources
This converter helps you understand APR in concrete terms by translating annual interest rates into daily, weekly, monthly, and yearly costs.
APR to Daily Rate Conversion
Credit cards use daily periodic rate (DPR) calculated as APR ÷ 365. This daily rate compounds over time, making debt more expensive than it appears.
Source: CFPB - Understanding APRTypical APR Ranges (2024)
Excellent credit (750+): 13-17% APR
Good credit (700-749): 17-21% APR
Fair credit (650-699): 21-25% APR
Poor credit (below 650): 25-29.99% APR
Compound Interest Effect
Unlike simple interest, credit card interest compounds daily. Each day's interest is added to your balance, so you pay interest on interest. This makes long-term debt exponentially more expensive.
Source: CFPB - How Compounding WorksNational Average APR
As of 2024, the average credit card APR is 20.74%, meaning a $5,000 balance costs about $2.84/day or $1,037/year in interest if unpaid.

Why Daily Cost Matters More Than APR
When you see "18% APR," it's easy to ignore. It's just a number. But when you realize that means you're spending $2.47 every single day on a $5,000 balance, it becomes real. That's $75/month, $900/year—money that could go toward savings, investments, or paying off the debt itself.
💡 The Coffee Shop Analogy
Imagine paying for a latte every morning but never drinking it. That's what high APR feels like:
- • $2-3/day: A coffee you throw away every morning
- • $5-7/day: Lunch you never eat
- • $10+/day: A streaming service you pay for but can't watch
When you frame APR as a daily expense, it's much easier to prioritize paying it off.
How to Use This Converter
1. Compare Different APRs
Enter different APRs to see how much you'd save with a lower rate. For example, compare your current 22% card vs a 0% balance transfer offer.
2. Understand Your Actual Costs
Enter your exact balance and APR to see what you're really paying. Use the daily cost to motivate yourself to pay off debt faster.
3. Visualize Opportunity Cost
The calculator shows what you could buy with your daily interest cost. Use this to reframe debt as money you're losing every day.
4. Plan Your Payoff Strategy
Seeing the 10-year cost helps you understand why aggressive payoff matters. Even small extra payments dramatically reduce lifetime interest.
Real-World Examples
Example 1: Average Credit Card Debt
Balance: $7,951 (US average)
APR: 20.74% (US average)
- 📅 Daily cost: $4.52
- 📆 Monthly cost: $135.60
- 📅 Yearly cost: $1,649.40
That yearly cost could fund a vacation, emergency fund, or down payment savings instead.
Example 2: High Balance, High APR
Balance: $15,000
APR: 24.99%
- 📅 Daily cost: $10.27
- 📆 Monthly cost: $308.10
- 📅 Yearly cost: $3,748.50
At $10.27/day, you're essentially paying for a gym membership every day just to keep this debt.
Example 3: Moderate Balance, Good APR
Balance: $3,000
APR: 14.99%
- 📅 Daily cost: $1.23
- 📆 Monthly cost: $36.90
- 📅 Yearly cost: $448.95
Even with a relatively low APR, $449/year is still significant—nearly a month of groceries or several months of streaming services.
What to Do With This Information
Calculate Your Break-Even Point
If a balance transfer card charges a 3% fee, divide that fee by your daily interest cost to see how many days it takes to break even. For $5,000 at 18% APR, the $150 fee breaks even in 61 days.
Track Your Progress
Use the daily cost as a motivator. Every time you make a payment, calculate how much you've reduced your daily interest "subscription."
Set Mini-Goals
Aim to reduce your daily cost by $1. On a $5,000 balance at 18%, that means paying down $2,028 in principal. Celebrate when you hit it!
Refinance or Transfer
If your daily cost is over $3, strongly consider a 0% balance transfer or personal loan consolidation. The daily savings add up fast.
✅ Success Story Template
Use this mental model to stay motivated:
"Right now, I'm paying [daily cost] every single day just to keep this debt. That's [yearly cost] per year—enough to [what you could do with that money instead]. If I pay it off in [months], I'll save [total interest saved] and never pay that daily fee again."
