Daily vs monthly credit card interest accrual, explained
Reviewed by CC Payoff Calc Editorial Team. Last verified May 13, 2026.
Credit card interest accrues daily on virtually every U.S. consumer card, then is posted to your account as one Finance Charge at the end of each billing cycle. The Federal Reserve reports the Q1 2026 average credit card APR at 22.76 percent. That APR is converted to a daily periodic rate (DPR) of 22.76 divided by 365, or 0.06236 percent per day. Each day the issuer multiplies the day’s balance by the DPR. The daily figures are summed across the cycle and shown as a single interest charge on your statement. Daily compounding makes the effective annual rate slightly higher than the stated APR. Paying mid cycle lowers the average daily balance and trims the finance charge. Here is the exact math, the Regulation Z reference, and worked examples.
Plan
Daily accrual is the U.S. standard
Federal Reserve G.19 Consumer Credit data, Q1 2026, lists the average APR on credit card accounts assessed interest at 22.76 percent. That number is an annual rate, but cards do not accrue interest once a year. They accrue every day.
The mechanism, identical at Chase, Discover, Capital One, American Express, Citi, Bank of America, Wells Fargo, and almost every other major issuer:
- The annual percentage rate (APR) on the card is divided by 365 to produce the daily periodic rate (DPR). A 22.76 percent APR card has a DPR of 0.06236 percent per day.
- Each day, the issuer multiplies the current outstanding balance by the DPR to compute that day’s interest accrual.
- At the end of the billing cycle, the issuer sums the daily accruals into one Finance Charge line item on the statement.
The legal authority for this presentation is Regulation Z, 12 CFR 1026.7, which requires issuers to disclose the periodic rate used to compute the finance charge. The same regulation (12 CFR 1026.6) governs the Schumer box disclosures you see on the back of the cardholder agreement.
Daily accrual + monthly posting
The confusion between “daily” and “monthly” comes from the distinction between accrual and posting. Accrual is the moment-by-moment growth of the interest owed. Posting is the moment the issuer records the charge on your account ledger.
On a 22.76 percent APR card with a $2,000 balance held flat for 30 days:
- Day 1 interest: $2,000 times 0.0006236 equals $1.247
- Day 2 interest: $2,001.25 times 0.0006236 equals $1.248 (because daily compounding adds yesterday’s interest to today’s balance)
- Day 30 interest: the daily figure on day 30, after 29 days of compounding
- Total: roughly $37.84 posted as one Finance Charge line at cycle close
The statement shows one $37.84 line item, but the underlying calculation walked daily across 30 days. The CFPB credit card interest explainer and the CFPB Truth in Lending Act overview describe the same structure.
Why issuers use 365 (sometimes 360)
The DPR denominator is normally 365, but a small number of issuers use 360 to mirror the older bank-day convention. A 360-day denominator produces a slightly higher DPR for the same APR (22.76 divided by 360 equals 0.06322 percent per day) and slightly more interest over a year. The cardholder agreement specifies which denominator applies. Synchrony Financial, Comenity, and a few retail co-branded products have historically used 360; Chase, Discover, Capital One, Citi, and Amex use 365.
The OCC’s Comptroller’s Handbook on Credit Card Lending describes both conventions as accepted industry practice. Either way, daily accrual is the rule, and the denominator is fully disclosed.
Calculator
Worked example: $4,000 balance, 22.76 percent APR, 30 day cycle
The pillar APR interest calculator accepts your balance, APR, and cycle length, then returns the finance charge using the average daily balance method.
Inputs:
- Average daily balance: $4,000
- APR: 22.76 percent
- Daily periodic rate: 0.06236 percent
- Days in cycle: 30
Math:
- DPR x average daily balance = 0.0006236 times $4,000 = $2.494 per day
- $2.494 per day times 30 days = $74.82 finance charge for the cycle
That single $74.82 line is what appears on the statement. Same APR, $2,000 balance, 30 day cycle produces $37.41. Doubling the balance doubles the interest, every time, because the average daily balance is linear in the underlying balance.
Comparison table: finance charge at 22.76 percent APR by cycle length
The average billing cycle length is 28 to 31 days; issuers may vary slightly month to month. A $5,000 average daily balance at 22.76 percent APR yields these finance charges:
| Cycle length (days) | Daily interest charge | Cycle finance charge |
|---|---|---|
| 28 | $3.118 | $87.30 |
| 29 | $3.118 | $90.42 |
| 30 | $3.118 | $93.54 |
| 31 | $3.118 | $96.66 |
The daily rate is constant; only the number of days changes the finance charge. Longer cycles cost more interest. Many issuers (Chase, Citi) let you change the cycle close date once per year, which moves your due date but does not change the per-day interest math.
Why the effective annual rate exceeds the stated APR
Daily compounding makes the actual annual cost slightly higher than the nameplate APR. The math, from Federal Reserve Regulation Z Comment 14:
- Stated APR 22.76 percent
- Daily periodic rate (1 + 0.2276/365) = 1.0006236
- Effective annual rate = 1.0006236 raised to the 365th power, minus 1, equals roughly 25.55 percent
The effective annual rate is the number you actually pay on a revolved balance held flat for a year. The CARD Act of 2009 requires the stated APR to be displayed prominently in the Schumer box, but the effective annual rate (sometimes called APY in deposit accounts) is what your balance actually grows by under daily compounding. For a deeper walk-through, see the sibling page on daily compounding.
Strategies
Pay mid cycle to lower the average daily balance
The average daily balance is the sum of each day’s ending balance, divided by the number of days in the cycle. A mid cycle payment reduces the balance for the remaining days, which lowers the average and the finance charge.
Example, $4,000 balance on a 30 day cycle at 22.76 percent APR:
- Pay $0 mid cycle: average daily balance $4,000, finance charge $74.82
- Pay $1,000 on day 15: average daily balance $3,500 (15 days at $4,000 + 15 days at $3,000, divided by 30), finance charge $65.47
- Pay $1,000 on day 1: average daily balance $3,067 (1 day at $4,000 + 29 days at $3,000, divided by 30), finance charge $57.36
A $1,000 payment made on day 1 saves $17.46 in interest on that cycle versus paying on day 30. The savings compound over many months. The sibling page on mid cycle payments shows the full year math.
Pay the statement balance in full to avoid interest entirely
If you carry no balance forward, your card grants a grace period (typically 21 to 25 days from statement close to due date). During grace, new purchases do not accrue interest. The grace period only applies when the previous statement was paid in full.
Losing grace because of a single revolved balance is one of the most expensive mistakes in personal finance. The CFPB’s grace period explainer and the sibling page on grace periods walk through how to re-establish grace after a missed cycle.
Watch the penalty APR trigger
Missing a payment by 60 days or more typically triggers the penalty APR clause in your cardholder agreement. Post-CARD Act, the penalty APR can apply only to new transactions (not existing balances) and must be removed if you make six consecutive on-time payments, per 12 CFR 1026.55. Penalty APRs commonly run 29.99 percent, which translates to a daily periodic rate of 0.0822 percent, or roughly $4.11 per day on a $5,000 balance.

FAQ
Frequently asked questions
Does credit card interest accrue every day or once a month?
Almost every U.S. credit card accrues interest daily using a daily periodic rate (DPR), then charges the accumulated daily interest to your account once per billing cycle. The DPR is your APR divided by 365 (or 360 for some issuers). For a 22.76% APR card, the DPR is roughly 0.06236 percent per day. Daily accrual is required by Regulation Z when the issuer uses the average daily balance method.
What is the daily periodic rate on my credit card?
The daily periodic rate (DPR) is your APR divided by 365 days. For the Federal Reserve Q1 2026 average credit card APR of 22.76 percent, the DPR is 0.06236 percent (22.76 divided by 365). The issuer multiplies your average daily balance by this DPR, then by the number of days in the billing cycle, to calculate the finance charge. The DPR appears in your Schumer box and statement disclosures.
Is daily compounding worse than monthly compounding?
Yes, slightly, on revolving balances. Daily compounding adds each day’s interest to the principal that earns the next day’s interest. On a 22.76 percent APR card, the effective annual rate from daily compounding is roughly 25.55 percent (1.000624 raised to the 365th power, minus 1). Monthly compounding at the same APR would produce roughly 25.31 percent effective annual. The difference is small per month but real.
Why do statements say interest is charged monthly?
The statement charges (posts) interest once per billing cycle, but the underlying calculation accrues daily. Each day, the issuer multiplies the current balance by the daily periodic rate to compute that day’s interest charge. At the end of the cycle, the daily charges are summed and posted as one Finance Charge line on your statement. This is the standard Regulation Z (12 CFR 1026.7) presentation.
Can I pay mid cycle to reduce daily interest?
Yes. Paying mid cycle lowers your daily balance for the remaining days of the cycle, which lowers the average daily balance used in the finance charge formula. A $300 payment made on day 15 of a 30 day cycle reduces the average daily balance by $150, saving roughly $0.09 per day in interest on a 22.76 percent APR card. The savings scale with payment size and how early in the cycle you pay.
