The average daily balance method charges interest on what was actually outstanding each day. The calculator on this page handles the installment side: amount, annual rate and months in, payment and interest out.
Average daily balance calculator: how it works for St. Charles, MO landscapers
- List each day of the billing cycle with the balance owed at the end of that day
- Add the daily balances together
- Divide the sum by the number of days in the cycle
- Multiply the average by the annual rate and by the days in the cycle
- Divide by 365 or 360, whichever year the agreement uses
In words: write down the balance for each day of the cycle, add the daily balances, and divide by the number of days. Multiply that average by the annual rate and by the days in the cycle, then divide by the days in the year the agreement uses (365 or 360).
A landscaping crew that draws for a mulch delivery mid-month and pays down after a property manager’s check clears pays interest only for the days the money was out. The calculator on this page does not track draws; it estimates a fixed installment on an amount you enter, the monthly payment, total interest and total repaid, in your browser only.
Average daily balance method calculator for real estate offices in St. Charles County, MO
Illustration only, invented figures: an office’s line over a 31-day cycle at an annual rate of 11.5%.
| Days | Balance | Balance × days |
|---|---|---|
| Days 1–10 (10 days) | $8,000 | $80,000 |
| Days 11–24 (14 days) | $20,000 | $280,000 |
| Days 25–31 (7 days) | $15,000 | $105,000 |
| Total | $465,000 |
Dividing $465,000 by 31 days gives an average daily balance of $15,000. In this example the office drew $12,000 on day 11 for a marketing push and paid $5,000 back on day 25 when a commission arrived.
Average daily balance calculator 31 days: how it works for St. Charles, MO landscapers
In this example, with a 365-day year, the 31-day interest on that $15,000 average is $15,000 × 11.5% × 31 ÷ 365, about $146.51. In this example, if the agreement uses a 360-day year, the same balance costs about $148.54, because each day carries a slightly larger slice of the annual rate.
A 31-day month carries one more day of interest than a 30-day month on the same balance. For a crew comparing statements from month to month, the number of days in the cycle explains part of the difference before any change in draws.
Line of credit interest calculator daily in St. Charles, MO: what home builders compare
Daily interest is the balance times the annual rate divided by the year’s days. In this example, at $20,000 outstanding and 11.5%, one day costs about $6.30. A builder holding a draw for lot costs can multiply that figure by the days until a closing repays it.
Daily figures also help a builder decide whether to repay a draw early. In this example, paying down $10,000 ten days sooner saves ten days of interest on that amount, which is easy to work out by hand and easy to weigh against holding the cash for the next invoice. A statement that shows the daily balance, or at least the dates of each draw and payment, makes this check possible; ask the partner whether its statements do.
When a balance stops revolving and converts to installments, the calculator on this page applies. Illustration only, invented figures: $15,000 converted at 11.5% over 12 months is $1,329.23 a month, $15,950.76 repaid and $950.76 in interest.
