Introducing the Forecasting Calculator

Picture this: You’re pulling your hair out because you can’t decide if you should expand your business, launch that new marketing campaign, or maybe buy that stock you’ve had your eye on.

Forecasting these scenarios manually can feel like reading tea leaves—uncertain and hazy. That’s where the Forecasting Calculator comes to the rescue, acting as a consultant to understand where you’re headed—instantly.

I created the forecasting calculator out of a personal need. For years, I struggled to find a tool online that would allow me to forecast the future, based on your current numbers, like growth rate, page views per month, sales per month, etc.

And forecasting is important, that much is for sure. Forecasting helps you set both motivating and attainable goals—and gives you insight into how well your operation is performing compared to the competition.

Without insight into the accurate prediction of the future, it’s hard to know what to prioritize in the present. And that’s where the Forecasting Calculator comes in. It’s a tool I decided to code because I needed a dead simple way to project and see my numbers in the future based on today’s performance.

In this article, I’ll first start with a definition of forecasting, why it’s important, and what you can use forecasting for. But it doesn’t stop there, we’ll also talk about how to use the Forecasting Calculator step-by-step and walk you through specific examples of using the calculator.

So, are you ready? Let’s dive in!

How Does the Forecasting Calculator Work?

The Forecasting Calculator uses an algorithm that takes your current numbers and extrapolates them using the growth rate you provide.

You input your current number that you want to forecast (ie, sales), your current growth rate, and how long you want the forecast to run. And…boom! You get a shiny, easy-to-understand chart predicting what those numbers will look like down the road. Because it uses your current numbers, it’s uncannily accurate.

For example, if you want to forecast sales, you enter your current sales, say $10,000, and a growth rate of 5%. The calculator then runs its magic to give you a future outlook. Of course, you can decide how long you want the forecast to go.

A Step-By-Step Guide to Using the Forecasting Calculator

Using the Forecasting Calculator is extremely easy. However, if you’re stuck at all, just use the following to get your accurate forecast:

  1. Enter Current Metrics: This could be anything from sales to monthly expenses. This represents the current number. For example, if you’re using this as a Sales Projection Calculator, enter your current sales in the Current Metrics field.
  2. Select the Growth Rate: Input the rate at which you expect to grow or you are currently growing. Make sure it’s a percentage!
  3. Choose the Timeframe: How long into the future do you want to peek? Choose your duration.
  4. Hit Calculate: This is where the magic happens. A beautiful chart emerges showing your forecasted metrics.
You Can Try Different Intervals and Durations

So, you may have noticed that the Forecasting Calculator allows you to choose growth rate intervals: daily, weekly, monthly, or annually.

Of course, these options add another layer of customizability.

For example, if you choose ‘daily,’ the calculator adapts its algorithm to project daily growth, keeping your forecast true to its timeline.

Whatever interval that you choose, that’s how many points on the graph will show up.

How to Use This Tool as a Sales Projection Calculator

You can absolutely use the Forecasting Calculator as a Sales Projection Calculator (also known as Sales Forecasting).

How do you do it? First, plug in your current sales numbers, your current (or expected growth rate), select the metric of “Sales” — and then click Generate Forecast.

Then, you’ll see how you’re going to do in the future. It’s really that simple.
