Shop Simple Interest Total Calculator (5 Years)

Calculate simple interest and the total amount to repay. This shop version uses a 5-year planning term as its starting point.

The Interest figure is the extra cost charged on the original principal alone, and the Total is the principal plus that Interest, so the Total is the full amount to repay by the end of the term.

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 percent, term 5 years. Using the page formula, simple interest is $10,000 times 5 divided by 100 times 5, which is $2,500.00. The total to repay is $10,000 plus $2,500.00, which is $12,500.00. That is the calculator output for these defaults. Because time is an input on this page, each year page gives a genuinely different answer: interest grows by exactly $500 for every extra year, since 5 percent of $10,000 is $500 a year and simple interest never compounds. Interest is still below the $10,000 borrowed at 5 years, but it reaches the full principal at 20 years, when the total doubles to $20,000.

Who this term suits for a shop owner: a shop taking a short loan for a till system, a refrigeration unit, or a small refit that must be paid off inside one lease term, where the $2,500 interest cost is easy to weigh against a few years of shop takings.

FAQs

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

Is this shop 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.

Is $2,500 of interest a lot on a $10,000 shop loan over 5 years?
It is $500 a year for 5 years, and the total to repay is $12,500. Whether that is a lot depends on the shop: compare the $500 a year with the extra takings the loan is meant to create, such as a faster till or a working fridge, and remember fees and taxes are not counted here.

Why is the interest exactly $500 a year here?
Simple interest is charged only on the original $10,000, never on interest already added. At 5 percent, one year of interest is $10,000 times 5 divided by 100, which is $500, and every year adds the same $500.

What if the shop repays early, after 3 years?
Using the same formula, 3 years of interest is $10,000 times 5 divided by 100 times 3, which is $1,500, so the total would be $11,500. That is a formula calculation for 3 years, not a page output, and a real lender may also charge an early repayment fee.
