A farm overdraft offer has more moving parts than its headline rate. Here is how the base rate, margin, line fee, security and annual review combine into what you pay, and how RIC loans and Farm Management Deposits compare for seasonal cash flow.
Quick Answer
A farm overdraft is priced as a base rate plus a margin set by the lender, with a line fee charged on the whole limit, and the margin moves with the farm's security, cash flow budget and history. Read the offer line by line against the overdraft rates and fees guide, and see how Switchboard structures revolving limits on the business line of credit page.
Also called: farm overdraft, rural overdraft, agribusiness overdraft, agri overdraft. They name the same product, though agribusiness overdraft can also cover processors and agricultural contractors, not only producers.
What sets the interest rate on a farm overdraft?
The interest rate on a farm overdraft is set by two things: a base rate the lender publishes and moves, and a margin it adds for your farm's risk. The quoted rate is a base rate plus a margin, and the full cost then adds fees that sit outside the rate. When a farm offer comes across the desk, what lenders actually look at first to set that margin is the security behind the limit, the cash flow budget for the season, and how the account has behaved through past seasons.
That is why two neighbouring farms can be quoted different prices in the same week. The base rate is shared by every borrower on that product. The margin is personal to the file. A teardown of the offer starts by splitting it into those parts, then reading each fee line against the limit.
Offer lines that show the real price
- Base rate named, with how and when it moves
- Margin stated as its own figure
- Line fee stated against the limit
- Review date and any review fee
- Security listed asset by asset
Offer lines to question first
- One all-in rate with no base and margin split
- Line fee wording unclear on limit or balance
- Excess or overlimit charges not stated
- Margin changes allowed with no notice period
- Security wider than the limit needs

How do the base rate and the margin work on a rural overdraft?
On a rural overdraft, the base rate is the lender's reference rate for the product and the margin is the extra it charges on top for your file. The base rate is usually variable and moves at the lender's discretion, often after a change in the cash rate, so one move flows through to every farm priced off that base. How cash rate changes pass through to overdraft pricing in general is set out in the business overdraft rates and fees guide.
The margin is where the negotiation sits. It is set at approval and usually held until the next review, although most offers let the lender change it on notice. Some lenders quote a single headline rate instead. Ask for the split, because a single figure hides which part will move with the market and which part you can argue on the strength of your file.
Interest is charged only on the drawn balance, typically calculated daily and debited monthly, depending on the lender. On a farm that daily calculation matters: a balance that sits near the peak for three months costs far more than the same peak held for three weeks, even at an identical rate.
How do farm security and loan to value change the rate?
Farm security and the loan to value ratio change the rate because they change how much the lender stands to lose if the season goes badly. Farm land and water usually price better than an unsecured limit, though this varies by lender, and a limit backed by a registered mortgage over the farm at a comfortable loan to value ratio typically draws a lower margin than one supported only by a general security agreement over stock and plant.
Lenders weigh each type of farm security differently. Freehold land is the strongest. Water entitlements can be taken as security where they are separately held and tradeable, though lenders usually discount them for price swings. Livestock, crops and machinery are normally covered by the general security agreement and registered on the PPSR, and they move a lender's comfort less than land does. How lenders value rural land, and the loan to value limits that commonly apply to it, is covered in farmland as loan security.
A lightly secured farm overdraft is possible for smaller limits, but the margin reflects it, and a director's guarantee is usually still required where the farm trades through a company or trust. The usual shape for a working family farm is a secured limit over the land, with stock and plant sitting under the general security agreement.
What fees sit on top of the interest rate?
The fees on top of a farm overdraft's interest rate are usually an establishment fee, a line fee, excess or overlimit charges and a review fee, and together they can matter as much as the margin. The line fee is charged on the limit, not the balance, typically, so it applies to the whole facility whether you draw it or not. The table below is illustrative; the names and the mix of fees vary by lender.
| Price line | What it is | What moves it |
|---|---|---|
| Base rate | The lender's published reference rate for the product | Lender decisions, often following the cash rate |
| Margin | The lender's add-on for your file's risk | Security, loan to value, the season's budget, account history and the size of the relationship |
| Line fee | A charge for having the limit available | The size of the limit, not how much you draw, typically |
| Establishment fee | A one-off charge to set up the facility | Limit size and how complex the security is, varies by lender |
| Excess or overlimit charge | Extra interest or a fee when the balance runs past the limit | How far and for how long the balance runs over |
| Review fee | A charge at the annual or periodic review | Lender policy; some waive it, varies by lender |
Read the fees together with the rate. A low margin with a heavy line fee can cost more over a year than a higher margin with no line fee, especially on a limit that sits mostly undrawn outside the peak. What happens when the balance runs past the approved limit, and how excess interest is usually charged, is covered in what happens when you go over a business overdraft limit.
How is a farm overdraft priced differently from a standard business overdraft?
A farm overdraft is priced differently from a standard business overdraft because the lender is pricing a seasonal swing, not a steady balance. A standard overdraft is typically assessed on regular monthly turnover. A farm overdraft is assessed on the season's cash flow budget, with the balance expected to climb through planting or the growing period and fall when harvest, wool, livestock or milk income lands.
Three things follow for the price. First, the limit is set at the season's peak, so line fees are paid on a figure the farm may only need for part of the year. Second, the lender expects the balance to come back down after harvest, and an account that does not clear as budgeted is read as a warning sign at review. Third, the annual review resets the price: it usually follows the year-end accounts and next season's budget, and that is when margin, line fee and security are reopened.
Rural teams at major banks and specialist agribusiness lenders typically treat that swing as normal. A general business lender reading a farm's statements may not, which can show up as a higher margin or a smaller limit. The wider set of farm finance types, and how lenders read farm income, is covered in the agribusiness finance guide, and the other finance options for owner-operators sit on the Business Owners Hub.
Why does the limit you ask for change what you pay?
The limit you ask for changes what you pay because the line fee, and often the establishment and review fees, are charged on the limit, while interest is charged only on what you draw. The peak limit you ask for is the limit you pay for, all year, including the months the account sits close to nil.
That creates a trade-off. Ask too low and the farm risks running past the limit at the worst point of the season, with excess charges and a harder conversation at review. Ask too high and you pay line fees on headroom you never use. Working out the right peak from the season's budget is a limit question rather than a price question, and it is covered in the seasonal farm finance guide.
On cost alone, the useful check is simple: compare the line fee on the full limit with the interest on the average drawn balance across the year. If the line fee is a large share of the total, the limit may be bigger than the farm needs, or part of the need may sit better in a different product. If a lender has already cut the limit at review, what to do when the bank reduces your overdraft limit sets out the options.
Farm overdraft, RIC concessional loan or Farm Management Deposits: which costs less for seasonal cash flow?
A farm overdraft, a RIC concessional loan and Farm Management Deposits do different jobs, so the one that costs less depends on which part of the cash flow gap you are filling. Concessional loans sit beside the overdraft, not instead of it. The Regional Investment Corporation offers concessional loans to eligible farm businesses on its own criteria, and those loans are term debt rather than a revolving limit you draw and repay through the season.
| Option | What it does | How the cost works | Where it fits |
|---|---|---|---|
| Farm overdraft | A revolving limit drawn through the season and repaid from farm income | Interest on the drawn balance plus a line fee on the limit, typically | The in-season swing: inputs, wages, contractors and timing gaps |
| RIC concessional loan | A term loan for eligible farm businesses, assessed on RIC's criteria | Concessional interest set by RIC, on a set repayment schedule | Longer-term needs such as investment or recovery; not a working limit |
| Farm Management Deposit | Pre-tax income set aside in a good year and drawn in a lean one | Works through tax rather than interest; some lenders let the deposit offset interest on farm debt, varies by lender | Smoothing income across years so the overdraft goes less deep in a poor season |
In cost terms, the overdraft is the most flexible and usually the dearest per dollar drawn. The concessional loan is cheaper but slower to arrange and narrower in what it funds. A Farm Management Deposit changes the tax position rather than the interest bill, unless the lender offers an offset arrangement. Used together, a deposit built in a good year can reduce how deep the overdraft goes in a lean one, which cuts interest and may support a smaller limit at review.
Check eligibility for each before you compare them. RIC sets its own eligibility and application process, and Farm Management Deposit rules depend on your income and how the farm is structured, which is a conversation for your accountant before it is a lending one.
A farm overdraft's price is more than its headline rate. It is a base rate plus a margin, a line fee on the limit, and set-up, excess and review fees, all shaped by the security behind the facility and reset at each annual review. Read the offer line by line, size the limit to the real peak, and let concessional loans and Farm Management Deposits do the jobs they do better.
Key takeaway: ask each lender to split the rate into base and margin, state the line fee against the limit and show the review terms before you compare offers.Frequently Asked Questions
Farm overdraft interest rates are set as the lender's base rate plus a margin for the individual farm's risk. The base rate moves with the lender's decisions, often after a cash rate change, while the margin reflects security, the season's cash flow budget and the account's history. How overdraft pricing is built more generally is covered in the business overdraft guide.
A rural overdraft is a business overdraft set up for a farm or agribusiness, with a limit sized to the season's peak rather than a steady monthly balance. It is drawn through the costly part of the season, repaid as income lands and reviewed each year. Rural land is usually the main security, as explained in farmland as loan security.
The interest rate of an overdraft on a farm is the lender's base rate plus a margin, charged only on the drawn balance and typically calculated daily, depending on the lender. Fees such as the line fee are charged separately against the credit limit and are not part of the quoted rate. Because the rate is variable, check how the lender sets its base rate and when it can change the margin.
An overdraft that suits a farm with big costs between harvests and lumpy income is one sized to the season's peak, with repayment expected after harvest rather than in equal monthly amounts. Price it on the full limit as well as the expected drawn balance, because line fees usually apply to the whole facility. How a seasonal limit is structured and sized is covered in the seasonal farm finance guide.
A line fee on a farm overdraft is usually charged on the whole limit, including the unused part, though this varies by lender. Interest applies only to the drawn balance, but the line fee is the cost of having the limit available. How interest and repayments run on the drawn balance is set out in how business overdraft repayments work.
