What Is an Online Calculator?
An online calculator is a digital tool that allows users to perform mathematical calculations without the need for manual computations. In South Africa, online calculators are useful for a variety of tasks such as calculating tax refunds, mortgage repayments, currency conversions, and more.
How to Calculate Using an Online Calculator Manually
An online calculator typically uses a specific formula to calculate results. For example, to calculate compound interest, you would use the formula:
Compound Interest = P(1 + r/n)^(nt) – P
Where:
- P = principal amount
- r = annual interest rate (decimal form)
- n = number of times interest is compounded per year
- t = number of years the money is invested for
For example, if you want to calculate compound interest for an amount of R10,000 at an interest rate of 5% compounded monthly for 5 years, you can input these values into an online calculator to get the result.
