What the debt costs to service.
Serviceability is the centre of every rural credit assessment. This produces the figure, on the amount, rate and term you enter.

What this tool models
A scheduled facility, over a term this shape can hold.
Farm term debt is frequently larger and considerably longer than the ranges here, running for decades rather than years and secured by a mortgage over the land. The arithmetic is the same and the scale is not, so treat the output as the shape of a repayment rather than as a model of a full land facility. For machinery, livestock and shorter arrangements, the ranges here cover the ordinary case directly.
The three inputs
What each one does to the figure.
The amount moves the repayment in direct proportion, which is the least interesting of the three. The rate moves the interest component and therefore the total, and on a long facility a difference of a single percentage point compounds into a substantial figure across the life of it.
The term is the one worth experimenting with. A longer term lowers the repayment and raises the total interest, and on a rural facility the right term is set by the life of the asset rather than by the lowest comfortable payment. A development that produces for thirty years financed over five is the most common structural error in the sector.
What the tool does not model is the shape. Rural repayments are frequently weighted toward the months income arrives, which changes a farm’s year considerably without changing the annual total by much. That structure has to be asked for and it is worth asking for.

Reading the output
Serviceability is tested against a poor season, not this one.
A rural lender assessing a facility tests the repayment against conservative production and prices rather than against a recent good year. That is the assessment this figure is going into, and it is worth doing the same test before applying.
The useful exercise is to take the repayment this tool produces and set it against the farm’s worst recent season rather than its average. Where it is comfortable against the poor year, the facility is well sized. Where it is only comfortable against a good one, the amount or the term needs revisiting before a lender does it.
That is also the answer to a repayment that looks affordable and is declined. The lender is not disputing the arithmetic; it is applying a different season to it.
What the tool does
The arithmetic behind the figures, and what it leaves out.
In its scheduled mode the calculator applies the standard amortising formula, spreading an amount and its interest evenly across the term and converting the monthly result to a weekly one. In its revolving mode it calculates the interest cost of an average drawn balance instead, which is the honest output for a seasonal facility that never amortises.
It excludes every fee. Establishment and line fees, review charges, valuation and legal costs, and any security disbursements are all real and none of them is here, because they vary by lender in ways no formula can anticipate. On a rural facility the valuation and legal costs in the first year can be substantial.
It also excludes seasonal repayment structures, which are common in rural lending and which change the shape of a schedule without changing its total by much. And it excludes every tax effect, which on a farm is a larger omission than it would be elsewhere. It is a way of seeing how amount, rate and term interact before a conversation with a lender, and it is not a quote, an application or an offer of credit. Nothing entered here is transmitted anywhere.

FAQ
The farm loan calculation, questions
Does this model a full farm term loan?
It models the arithmetic rather than the scale. Land-secured term debt is frequently larger and longer than the ranges here, so treat the output as the shape of a repayment. For machinery, livestock and shorter facilities it covers the ordinary case directly.
Are fees included?
No. Establishment and line fees, review charges, valuation and legal costs and security disbursements are all excluded, and on a rural facility the first-year valuation and legal costs can be substantial.
Does it model seasonal repayments?
No. Rural repayments are frequently weighted toward the months income arrives, which changes a farm’s year considerably without changing the annual total by much. That structure has to be asked for from the lender.
What term should be used?
One matched to the life of the asset rather than to the lowest comfortable payment. A development producing for decades financed over a few years is the most common structural error in rural finance.
How should the output be tested?
Against the farm’s worst recent season rather than its average, because that is what a rural lender does. A repayment comfortable only against a good year is a repayment that will be questioned.
Why was an affordable-looking application declined?
Ordinarily because the lender applied a conservative season to the same arithmetic, or because the total debt position rather than this facility alone was the constraint.
Are the figures here quotes?
No. Everything on this page is indicative and illustrative. Actual rates, terms and structures come from a lender after assessment, and nothing here is an offer of credit.
Is anything entered here transmitted?
No. The calculator runs entirely in the browser, nothing is sent anywhere and no personal details are collected on this site at all.
