Almost every business sooner or later runs short of working capital — the money that covers day-to-day costs while you wait for customers to pay. Then comes the question of how to finance that gap: a business loan, a credit line or an overdraft. In this article we compare the three, look at when each one fits, what they cost and how to track them without losing control.
What working capital is
Working capital is the difference between current assets (cash, receivables, inventory) and current liabilities (suppliers, taxes, payroll). Put simply — it is the money the business runs on day to day, before its receivables are collected.
A working capital shortfall does not mean the business is in bad shape. Often it is the opposite — growing and seasonal companies need financing precisely because they are expanding. The question is which instrument.
Types of working capital financing
Business loan (term loan)
You receive a fixed amount up front and repay it in installments over a set term. It suits a specific, predictable need — buying equipment, a large order of materials, an investment. The interest rate is usually lower, but you pay for the full amount from day one whether you use it or not.
Credit line (revolving credit)
The bank approves a limit you draw on when you need to and repay when you can. What you repay becomes available again — hence "revolving". You pay interest only on the amount drawn. Ideal for recurring but unpredictable working capital needs.
Overdraft
An overdraft is permission to go below zero on your current account up to a set limit. It is essentially a credit line wired directly into your account — payments go through automatically even when the balance is zero. Interest accrues only on the negative balance, and usually only for the days you are in the red.
Overdraft vs. credit line: the key differences
- Access to the money — the overdraft is built into the account and kicks in automatically; a credit line is usually drawn on request.
- Purpose — the overdraft covers short-term, daily fluctuations; the credit line covers larger and longer working capital needs.
- Limit — overdrafts typically come with smaller limits than credit lines.
- Cost — the overdraft often carries a higher rate, but you pay only for the days in the red; a credit line is usually cheaper for longer utilization.
- Psychology — the overdraft is convenient, but it easily turns into a permanent negative balance if left unwatched.
When to choose which
- Choose a business loan when you have a single, predictable investment with a clear return.
- Choose a credit line when the working capital need is recurring but uneven — for example with seasonality or long customer payment terms.
- Choose an overdraft when you want a buffer for short-term swings in the account and the peace of mind that payments clear even during a temporary shortfall.
Many businesses combine them — a term loan for investments and an overdraft or credit line as the working capital buffer.
What it costs
The cost of financing is more than the interest rate. Check:
- Interest rate — fixed or floating, and on which amount it accrues.
- Commitment fee — sometimes you also pay a percentage on the undrawn part of the line.
- Arrangement and service fees — one-off and annual.
- Collateral — whether it is required and what kind.
The total cost of an overdraft used a few days a month can be lower than that of a loan you pay for all year — even at a higher rate. So compare actual usage, not just the percentage.
How to track your loans
The biggest danger with revolving instruments is losing track of how much you owe and when. That makes loan tracking just as important as the financing itself.
In Finsense you can register every instrument — term loan, credit line or overdraft — with its limit, interest rate and repayment schedule. For revolving credit and overdrafts the system tracks draws and repayments, so you always see how much is drawn and how much remains available. Loan payments flow automatically into the cash-flow forecast, so you plan the installments before they hit.
How not to over-borrow
Accessible financing is exactly as convenient as it is dangerous. A few rules keep you in the safe zone:
- Finance only working capital needs with working capital credit — do not use it to cover losses.
- The overdraft is a buffer, not a permanent balance. If you are in the red every day of the month, you probably need a more structured solution.
- Watch the ratio between installments and actual inflows — debt service must not choke the operating flow.
- Do not take a new loan to pay an old one without a clear exit plan.
What the bank looks at before approval
Before granting working capital financing, a lender typically weighs the turnover on your accounts, your revenue history, the revenue-to-debt ratio and the collateral. Tidy financial records and a clear cash-flow forecast not only speed up approval but often improve the terms — because they show you run the business on numbers, not by eye.
Frequently asked questions
What is the difference between an overdraft and a credit line?
The overdraft is built into the current account and kicks in automatically when funds run short. A credit line is a separate limit you draw on request, usually with a larger size and a lower cost for longer use.
Which is cheaper — a loan or an overdraft?
It depends on usage. The overdraft often carries a higher rate, but you pay only for the days in the red. A term loan has a lower rate, but you pay for the full amount over the full term.
What is revolving credit?
Credit with a limit you draw and repay repeatedly. Repaid amounts become available again, and you pay interest only on what is drawn.
How do I keep control over several loans?
Register every instrument with its limit, rate and repayment schedule in a single system, track drawn versus available, and include the installments in your cash-flow forecast.
