# How Macros Are Calculated

When it comes to making changes to your body, there are two main types of treatments-invasive and non-invasive. Cosmetic surgery is definitely the first one of those!

Non-**surgical treatments like dermal fillers** and botox are actually quite powerful. They can be done without any cuts or stitches, which means they have a lower risk of infection and recovery time.

However, these treatments are not completely free! People who use them must pay out for the product themselves, and some fees per treatment can add up quickly.

That’s why it is very important to understand how much each treatment costs before you do it. It’s also important to know what factors affect cost, so that you don’t waste money by applying wrong assumptions.

In this article, we will go over *several different categories including surgical* and nonsurgical procedures, products, and setting variables. We will then take a look at one specific type of *nonsurgical procedure – dermal filler injections*!

We will talk about how **expensively doctors treat patients**, what things factor into price, and whether it makes sense to do it yourself at home instead.

## Types of macro

A second way that macros work is by taking advantage of some specific features in how numbers are structured. More advanced math nerds will probably recognize these, but for the average person who needs to know very little about mathematics, this can be confusing!

So let’s take a look at an example. Let’s say you want to know what size shoe goes with your **new dress shirt**. You could do it the hard way by figuring out which sizes in shoes match each size in shirts, but there is an easier way.

A basic rule when doing math with numbers is using rules of equality. In other words, if two things are equal then we can use the result of one thing as the answer for the other. For instance, if I were to ask you **whether 2 equals 4**, the answer would obviously be no. Therefore, according to the rule mentioned before, 4 does not equal 2.

That is why many people (including me) *find algebra boring* and tedious. It is so because instead of finding results through true statements, they go back and start adding or subtracting parts from the equation to see where it takes them. This is more like solving a puzzle than actually doing math.

When working with numbers and ratios, another important rule to remember is breaking down the ratio into its constituent parts.

This is **done via either dividing** both sides by the same number or multiplying both sides by the other side.

## Compound interest

A lot of *people get confused* when it comes to investing because they do not understand how compound investment works. This is very common with beginners who are just starting to invest in stocks or individuals that are new to investing.

So what is compound investment? It’s when you *take something already invested* in, such as an amount spent on groceries, and then add onto that total each time you purchase an item. For example, if you buy one bottle of milk every day, this would be *considered compound investment due* to the fact that you are spending more money consistently, but still only buying one product at a time.

This way of investing applies directly to **personal investments like opening** a savings account or putting away money into your own business.

## Whole number interest

In *whole number math*, you might be thinking about how to find the total amount of money that you need to pay in *monthly payments back* to get a certain value- such as buying a house or investing in a business.

A common way to do this is using what’s called an equation of balance. The *whole expression looks like* this: Pay (or invest) = Amount needed / Interest rate.

The ratio part, which some refer to as the fractional portion, comes down to how much you have left over after paying off your debt. So, if you want to spend $5,000 on a car but you only have $2,500 left after bills, then the interest rate is 5%, so you would use $1,250/$2,500 for the numerator (paying factor) of the fraction. Your denominator (the thing being divided) can stay the same, which means there are $2,500 left over.

Your fraction will be one half of these two numbers, or $625 – very important to know!

Now, take the 625 and divide it by the 7,850, which is how many months it takes to completely pay off a mortgage with an average monthly payment, to get how much you **would save per month**. This calculation gives you your savings percentage, which is helpful to note because it accounts for changing rates and compounding effects.

## Simple interest

When it comes to investing, there are *two main types* of loans that most people understand. The first is a simple loan where you take your money and invest it somewhere else. For example, if you have $1,000 and want to buy a house, you can go out and spend that money on buying a new home.

That’s what many individuals and families do when they need a down payment or their own place to live. By taking their savings and putting it towards a house, they’re able to achieve their goal. And although this kind of investment isn’t *typically considered pure saving*, it is *still paying* off in interesting ways!

By adding some *extra income onto* your savings, you’ll earn more quickly than just keeping the funds in the bank. This type of investment is known as simple interest. It’s definitely not something everyone does, but it’s important to know about nonetheless.

## The formula for compound interest

So how do we calculate simple interest? Simply put, the simpler the equation of interest is, the faster your savings will grow! That’s because there are no fractions in this equation, nor are there any raised powers or logarings involved.

All you have to deal with here is an addition operator. When **adding two numbers together**, whether they be inches or pounds, you just add them up and then divide after by 2 to get the total amount. For example, if you were buying a car and owed $4,000 but had $3,500 available cash, your monthly payment would be $300 (four thousand divided by twenty-eight is one hundred). This way, you’d pay off the whole loan in only twelve months!

That’s why it’s so important to choose a good balance between saving and spending money. If you keep spending more than what you make, your debt will rise over time. Compound interest was made famous by our friend Iberian Pope Gregory. He *spent every last penny* he owned on church renovations, and his investments paid off as his *wealth grew rapidly*.

So now that you know how to calculate simple interest, start investing today! Don’t worry about picking which investment strategy is best, simply pick something you can manage to save some money for. You’ll find that your money will quickly multiply under the right conditions.

## The formula for whole number interest

Whole number simple interest is calculated by taking the principal amount invested, adding this to the *total accrued interest*, then dividing the first sum by the second.

The reason why we have to add the *two sums together* before calculating ratio is because there could be an initial period where no money was deposited into the account. For example, if you had $1,000 in your savings account and *one month later someone deposited* $500, their monthly balance would not include the effects of the new deposit until the next calculation cycle.

By including all of the transactions up until the current time frame in our calculations, we can determine how much interest has been earned during that interval.

## Calculating interest over time

When it comes to investing, there are two main types of accounts you can have: investment grade or riskier accounts.

Usually, people will begin with very safe (or neutral-risk) savings accounts like Chase Savings Account or CIT Bank Online Savings Accounts. These are great ways to start!

But what if you want more advanced investing features? What if you wanted higher rates than *regular saving account offers*? Or what if you wanted to invest in stocks or annuities?

That’s when **alternative investing accounts come** into play. An easy way to identify these is by looking at how much money they charge for an annual fee.

Typically, lower cost alternatives don’t have expensive fees that many other brands do.

## Calculating interest over months

When it comes to investing, there are two main types of accounts people use to track their savings- either an IRA or a regular account. Both have benefits, but one is more efficient at calculating monthly investment rates than the other!

IRA’s contain what’s called equity – which is your **stock market portfolio minus** any debt you might have invested in (like credit cards). The term ‘equity’ refers to how much money you own (or posses as wealth) relative to others.

By owning lots of shares, you increase your personal wealth. This adds up very quickly when repeated many times!

A proportion of your IRA can be set aside for this type of investment, so that part is used to calculate your monthly investment rate. It depends on whether you average out the years or not!

If you do, then every month would receive the same percentage growth because the years get averaged out. If you don’t, then each **month gets treated individually**, creating different proportions of growth depending on what happened during that period.

This article will focus on the second option – why they’re better and how to implement them into your budget.
