How a revolving business facility works
A line of credit provides access up to an agreed limit under the facility’s conditions. You draw the amount needed, then make repayments. Repaid principal may become available to use again, subject to the agreement.
This can be useful when payment gaps repeat and the amount needed changes. A term loan is a different comparison: it generally advances an agreed sum with a scheduled repayment period. The choice depends on the job, the availability required and the cost of keeping access open.
One month: see the limit, debt and available amount
Consider an illustrative $20,000 facility starting with no debt on 1 November. The business draws $10,000 that day, repays $4,000 of principal on 11 November, then draws $2,000 on 21 November. Assume drawings are permitted and all repayments are principal-only.
| Date | Movement | Principal owed after movement | Unused amount under the assumed limit |
|---|---|---|---|
| 1 November | Draw $10,000 | $10,000 | $10,000 |
| 11 November | Repay $4,000 | $6,000 | $14,000 |
| 21 November | Draw another $2,000 | $8,000 | $12,000 |
| 1 December, end of model | No further movement | $8,000 | $12,000 |
Swipe or scroll the table sideways to see every column.
The business has drawn $12,000 in total and repaid $4,000, leaving $8,000 owed. The $20,000 limit is not the amount borrowed. The unused amount is planning headroom, subject to the actual facility’s access rules.
Interest, facility fees and debt left to repay
For the same example, assume a constant 12% nominal annual interest rate, actual days divided by 365, no unused-limit fee and a $20 monthly facility fee. The model runs from 1 November inclusive to 1 December exclusive. Each balance lasts ten days. Interest and fees are paid separately rather than added to principal. These inputs are hypothetical, not advertised terms.
| Cost calculation | Illustrative amount |
|---|---|
| Interest on $10,000 for 10 days | $32.88 |
| Interest on $6,000 for 10 days | $19.73 |
| Interest on $8,000 for 10 days | $26.30 |
| Total interest, calculated before rounding | $78.90 |
| One monthly facility fee | $20.00 |
| Total modelled interest and fees | $98.90 |
| Principal still owed at the end | $8,000.00 |
Swipe or scroll the table sideways to see every column.
Displayed line items are rounded; the total uses unrounded interest. The $98.90 cost is separate from the $4,000 principal repayment and does not clear the $8,000 remaining debt.
Ask how the actual facility sets minimum repayments and whether any balance reduction is required by a review or expiry date. Atlas’s planner models the principal repayments you enter; it does not calculate a lender’s contractual minimum payment.
Which costs apply when you draw less—or nothing?
Interest may follow the drawn balance while other costs follow the approved limit, unused portion, individual draw or time the facility remains open. List each charge by its basis and timing before comparing two proposals.
- Interest: the balance used, rate convention, day-count basis and when it is charged.
- Facility or unused-limit charges: whether costs continue when the balance is zero.
- Establishment, draw and review fees: when they arise and whether they are deducted or paid separately.
- Extra payments, early closure and default: conditions that can affect the cost of using or leaving the facility.
Line of credit, overdraft or term loan?
| Decision | Line of credit / revolving funding | Term loan |
|---|---|---|
| Changing needs through a repeating cycle | Compare repeated draws and the cost of having access available. | Consider whether borrowing the full amount upfront creates unnecessary debt. |
| One project with a known repayment period | Check whether ongoing availability adds useful flexibility. | Compare a schedule matched to the project’s cash contribution. |
| Discipline in repaying principal | Set dates and amounts for reducing the balance. | Review the scheduled principal repayment and any final obligation. |
| Certainty of access | Check review, renewal, expiry and draw conditions. | Check conditions on the initial advance and any staged funding. |
Swipe or scroll the table sideways to see every column.
A business overdraft commonly operates through a transaction account, while other credit facilities may use a separate account or draw process. Product names do not establish the account arrangement, security or fees. Ask whether the proposal requires specific asset security, wider business security or personal guarantees.
Bring the usage pattern to Atlas
Atlas helps you assess the size and pattern of the funding need before the headline limit becomes the focus. Use the planner to map a normal cycle and a late-customer case. Record the peak balance, interest and fees, and the debt remaining at the end.
Share the purpose, approximate limit required and timing in your enquiry. Have the expected draws, principal repayments and existing facilities ready for the discussion. If the balance stays high every month, compare whether a term loan or an operating change better matches the underlying need.
What to prepare
- The maximum expected drawn balance and dates it occurs
- A sequence of expected draws and principal repayments
- A late-receipt case and a plan to clear or reduce the balance
- Every quoted fee, its basis and when it is paid
- Review/expiry dates, draw conditions and security or guarantees
- Existing credit limits and repayment commitments
Common questions
Do I pay interest on the full business credit limit?
Interest may be calculated on drawn funds, but separate facility or unused-limit fees can apply. Use the actual pricing schedule and compare the cash cost when you draw less as well as when you use the full limit.
Can I repay a line of credit and use it again?
That is a common revolving feature, subject to the agreement. Check which repayments restore availability, when the facility is reviewed and what can restrict a new draw.
Will minimum repayments clear the debt?
Not necessarily within the period you have in mind. Ask how minimum repayments are calculated and how much principal remains. The Atlas planner lets you set principal payments and see the ending balance.
Can a business line of credit be unsecured?
Some products are marketed as unsecured, but you must check asset-security and guarantee terms separately. Product availability and assessment vary. Atlas does not treat the label as a promise that no personal obligation is involved.
What is the difference between a line of credit and an overdraft?
Both can have revolving features. An overdraft is commonly linked to a transaction account, while a separate line of credit may use its own draw and repayment process. Compare the actual account setup, security, fees and review conditions.
Is a credit line suitable for a long-term purchase?
Compare the cost and repayment plan with a term or asset-finance structure. Repeatedly using a revolving balance without reducing it can leave a long-term debt, even where it began as short-term funding.
What can I discuss with Atlas before applying anywhere?
The size and frequency of the gap, the repayment plan, the costs you want to compare and the facility conditions you need to understand. An Atlas enquiry gives that discussion a starting brief and does not submit a lender application.
