How to Use an Interest Calculator

An Interest Calculator is one that is used by individuals or firms within the financial sector to determine the amount of interest that will be accrued by a person or firm or business to whom they are extending credit in any form.

The Interest Calculator exists in a number of forms. It can be a document with a formula that is embedded within a spreadsheet document like what Microsoft Excel offers; an Interest Calculator can also exist as a web-page, as in the case where financial firms create web-pages that have the interest calculator embedded within them. This assists prospective clients to use these pages to find out what interest they may incur if they decide to use the financial services belonging to that provider.

The Interest Calculator can also be the actual device used to process this interest figure, and in this case, we are talking about a calculator as a mechanical device.

An Interest Calculator can also exist as a written formula, one that is simply worked out mathematically, on paper.

Interest Calculators typically cover two forms of interest: simple interest and compound interest.

In the case of a mechanical device, it can be programmed to work out the different types of interest, that is, simple and compound interest.

In the case of embedded formula based documents like Microsoft Excel spreadsheets or even web-pages with embedded formula, variations can be made for calculating both simple and compound interest as well.

The same variation can occur when it is calculated as a mathematical formula: you can have a mathematical formula for simple interest and a variation of the same for compound interest.

Simple interest involves calculations involving three basic variables: the principal, the time period and the rate of interest for that specific block of time.

Compound interest rates take into account several factors. These include the principle, the rate of interest over a specific period of time, and the time period involved; however, it also includes an important variation: the rate at which the interest amount paid changes over the varying principal over time.

Some compound interest calculations incorporate an allowance for fluctuations like inflation rates as well as bank rates, insurance premiums and things that affect the returns the financial institution gets from the transaction. Compound interest rates can also take into account penalties for early payments or even late payments, as determined by calculations stipulated by the financial institution.

Interest calculators will thus obviously vary in the situations they are used. Simple interest calculations best serve one off payments and are rarely used for the complicated and more long term financial arrangements. Simple interest rates cover calculations or transactions that are usually more informal in nature.

Compound interest rate calculations are more typical of formal business arrangements that are found in insurance firms, banks, credit card companies, mutual fund managers as well as saving scheme firms.

Five Smart Financial Moves to Make before Switching Jobs

When switching jobs, it is important to be pragmatic when evaluating the new opportunity before you. Outlined below are some aspects of the new situation that you can examine carefully to make sure the new switch works out well for you.

Your New Contract

It would be particularly wise to only give in notice at your old job after you have received and carefully examined the contract for the new position you are being offered. Make sure that at the very least you seek a legal opinion on the validity of the contract, and whether the terms as expressed within it are a reflection of your understanding of the document. This includes remuneration, the terms under which you may leave that position, non-disclosure clauses as well as any other terms that may affect your future career and thus, your future financial stability.

Net Income

Ensure that you have correctly understood the calculations by which you arrive at your net income in your new job. This is a discrepancy that a lot of new employees make, and one that some employers do not take the time to point out, which results in your receiving significantly less than you had initially understood you were going to get as your net income.


Closely examine the benefits offered by the new position and note how they impact on your lifestyle. Do you have to travel further than you did for your original job? Does the cost-benefit analysis work out? Do you get paid overtime? Do you have the same health benefits? Are aspects important to your performance, like an entertainment allowance for a high-end marketeer, included in your benefits package? Carefully analyze your benefits terms to ensure they do not put you in a losing position.

Employee Schemes

Examine what schemes are on offer at the new job and take advantage of them. These often vary, and can include stock options, saving schemes, and things of that nature which can be vital to ensuring your medium to long term financial stability.

Account Management

It may be wise for you to look into who manages the financial accounts for the firm you are joining, at a banking level. It puts you on friendlier footing if you are banking with the same bank that handles your employer’s accounts, especially if you are joining a stable firm. Credit is significantly easier to access, and transactions are of course much easier to follow up on. Along side this, you would do well to ensure that you continue with any saving activity that you may have been carrying out at your previous position, or at the very least, start this valuable habit. If disbursements from your monthly income were being distributed between an expense and savings account, ensure the same process is maintained when taking on the new job.
