Free Fitness Calculators You Can Embed to Your Website

Being able to have tangible data to better plan out a weight loss or muscle gain routine is one of the main keys to success.

Too many people try to rely on just general guidelines for the average person and then wonder why their weight loss efforts fail.

But if you give readers the diet and exercise advice they need, based on personalized data, the results can be much better.

But why would you implement these tools directly?

Here’s why.

1. It’s convenient for your readers.

No matter how detailed you go into body fat loss, healthy dieting, or strength training, readers will need to work out a few things like their BMI, BMR, total daily energy expenditure, and their ideal macro profile.

But rather than send a reader to download an app or use a web-based tool on another site, it’s much more convenient if they can just plug in some data in a calculator on your site.

2. It keeps your readers engaged and avoids sending them someplace else.

When you’ve captured readers on your site to give them advice on their workout routine and how to manage or lose bodyweight, then the last thing you should do is send them somewhere else to get some necessary data.

If you send them to an app or another website, you’ve lost their attention, and they might not return.

But if you have a calculator embedded on your page, you won’t run that risk.

3. It builds credibility and authority.

Providing information about basal metabolic rate, daily energy expenditure, and body fat percent in a convincing way requires you to show expertise in the area.

You can achieve a lot of that through the way you explain complicated things in a clear way.

But if you then send readers to another website for a calculator, you could lose some of that credibility.

By embedding these calculators, you can position yourself as much more of an authority with full end-to-end advice.

Our BMI calculator is easy to embed and user-friendly. Here’s what you need to know about it.

Why Is A BMI Calculator Important?

Once you start covering any topics related to how and where you store body fat, people will be interested in understanding where their starting point is [1].

That can be for an audience of performance athletes or people who are just trying to lose some weight.

While the weighing scales can be helpful to an extent, they really don’t tell you the full picture of someone’s BMI.

If you can get people to focus on their BMI rather than just their weight, you can put them on a much better path.

What I mean is that once someone understands their BMI, they have a much better way to measure how and whether they are achieving their goals.

How Does A BMI Calculator Work?

Our BMI calculator works by taking input values about a person’s height and weight to calculate their approximate body fat.

Yes, this isn’t going to give you the exact BMI like a DXA scan would reveal, but for most people, it will be close enough to determine a starting point and plan milestones for a diet and exercise routine.

What Input Value Do Users Need?

The body fat calculator is one of our simplest calculators as it only requires height and weight.

We kept it simple because you don’t want to lose people with complicated calculators that require the user to get additional information about their diet and lifestyle.

Users can have good results about their body fat percent within seconds so that you can keep them hooked on the topic you’re trying to get across.

If your website provides any kind of advice on weight management, then you simply cannot avoid covering calories.

But you would be doing quite a poor job if you advised your readers to base their calorie intake on what the average man or woman might need.

Every athlete has different requirements, and the only way to provide good advice is by using the total daily energy expenditure of a person as a starting point [2].

Why Is A TDEE Calculator Important?

Understanding someone’s energy needs is vital when it comes to providing advice about how much or little food they should eat.

And because everyone has a different basal metabolic rate (BMR), this isn’t something that should be left to guesses or averages.

Providing good dietary advice is only possible with an accurate TDEE.

And when you have a calculator embedded on your page with a simple design, then you’ll gain a lot more trust with your readers that you know what you’re talking about.

How Does A TDEE Calculator Work?

Total daily energy expenditure is based on a calculation with specific input values like height, weight, age, and sex.

These values then provide the BMR, and when you add activity levels on top of that BMR, you know how many calories a person burns per day.

It’s a much more accurate value than basing someone’s BMR calories on just their height.

And from there, it’s possible to make better suggestions for a calorie deficit or calorie surplus.

What Input Values Do Users Need?

For the basal metabolic rate portion of the calculation, readers will need to input their age, sex, weight, and height. And by selecting their daily activity, they will have everything needed for calculating their calorie needs beyond their BMR.

It’s one of the easiest to use calculators that provides an immediate result about recommended calories.

The third diet and fitness calculator that is important for many health and fitness websites is all about calculating an ideal macro split.

While the TDEE calculator is great for giving you details about how many calories someone should be consuming, results could still vary because of a wrong macro balance.

Here’s why it’s such an important calculator.

Why Is A Macros Calculator Important?

Too many people fail with diets and workouts because they just focus on BMR and calories. But when you combine calories with a goal-based macro-split, then it becomes a lot easier to control body weight.

Imagine being able to give your readers advice about how to structure their diet based on protein, fats, and carb consumption without just giving them some general ballpark ranges.

By telling them what their exact macros should look like, you’ll set yourself apart from your competitors and gain a lot more credibility.

How Does A Macro Calculator Work?

A macro calculator uses just a few input values to assess how someone’s metabolism reacts to carbs, protein, and fats [3].

And depending on what a reader has as their body composition goal (from bulking to cutting and drastic weight loss), it’s then possible to calculate what percentage of their daily food intake should come from each of those macros.

What Input Values Do Users Need?

We have designed our macro calculator to be as easy to use as possible. As a result, your readers will only need to enter their age, sex, height, weight, exercise and fitness goals, and activity levels.

Within seconds, they will have detailed results on the screen to use for refining their diet to gain muscle mass or lose some love handles.
