Farm Simple Interest Total Calculator (15 Years)

Calculate simple interest and the total amount to repay. This farm version uses a 15-year planning term as its starting point.

—

The Interest figure is the extra cost of borrowing on top of the principal, and the Total figure is the full amount to repay over 15 years, so the gap between the two figures shows how much borrowing adds to the original amount.

Formula

Simple interest equals principal times rate times time, divided by 100.

How it works

Interest is charged only on the original principal, not on interest already added.

Worked example

Principal $10,000, annual rate 5%, term 15 years. Using the page formula, simple interest is $10,000 times 5 times 15, divided by 100, which is $7,500. The total to repay is $10,000 plus $7,500, which is $17,500. That is the calculator's own result for these defaults.

That is $500 a year for 15 years. Simple interest never charges interest on interest, so the yearly charge stays at $500 even in year 15, and the total rises only because more years have passed, not because the rate has grown.

Who this term suits on a farm: a farm funding a longer-lived improvement, such as a barn extension, field drainage, or a cold store, where the building or system should still be working when the loan is repaid and the steady $500-a-year charge can be planned around harvest income.

FAQs

What is simple interest?
Simple interest is interest charged only on the original amount, not on accumulated interest.

Is this farm calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Why does interest reach $7,500 after 15 years?
Because $500 a year for 15 years is $7,500, and the total to repay is $17,500. The yearly charge never rose, but 15 years of the same charge add up to three quarters of the amount borrowed.

Does simple interest ever charge interest on interest over 15 years?
No. Simple interest is charged only on the original $10,000 for the whole 15 years, which is why the yearly charge stays at $500. A compound loan would charge more in later years, because interest would be added to the growing balance.

Should a 15-year farm loan be compared with a compound loan?
Yes, before signing. Over 15 years a compound loan at the same 5% would cost more than $7,500, because later years would charge interest on earlier interest too. This page shows the simple-interest figure only, so use it as one comparison, not as the whole cost of borrowing.
