Enter Your Weight Goals

The first step in using the Excel weight tracker is to enter your personal data and weight goal information.

  • Go to the WeightGoals worksheet in the Excel Weight Tracker file
  • In the top green cell, choose the measurement system you want to use -- pounds or kilos

Warning: Consult your doctor for recommended target weight and weekly weight change goals. This workbook does not contain any qualified medical advice -- it is a tracking tool only.

NOTE: You can get the Stone weight tracker, if you prefer that measurement system

Green Cells

Next, fill in the remaining green cells. Consult your doctor for recommended target weight and weekly weight change goals.

  • Start date: The date you will start tracking your weight
  • Start weight: Your initial weight on the start date
  • Target weight: The weight that you want to reach (set targets with help from your doctor)
  • Lbs/kg per week: The weight change you want to achieve each week

Grey Cells

Do NOT enter anything in the grey cells.

There are formulas in the grey cells, to calculate the total weight change, and the target date when you will reach your goal.

Start Tracking Your Weight

After your goals are entered, you can start tracking your weekly results.

There is sample data in the workbook, so follow the steps below, to clear that data out, and replace it with your own data.

Clear the Sample Data

  • Go to the WeeklyWt sheet, where weekly weights are entered.
    • Note: This sheet also calculates your weekly weight change.
  • Select the green cells, where the sample dates and weights were entered
  • On your keyboard, press the Delete key, to clear those cells

Warning: Do NOT clear the Tgt Wt or Wt Change columns - they contain formulas.

Delete Unused Rows

This step is optional - you can delete the unused rows in the Weekly Weight table, or leave them there, to fill later.

Warning: Do NOT delete the first data row in the Weekly Weight table, directly below the table headings. That row contains the formulas, which are automatically entered in the rows below..

To delete any unused rows, follow these steps:

  • At the left side of the worksheet, drag down over the row number buttons, to select the unused rows in the table
  • Right-click one of the selected row buttons
  • In the pop-up list, click on Delete, to remove the selected rows from the worksheet.

Weekly Weight Tracking

After you've finished the initial setup for the Weight Tracker, all you have to do is enter your latest results each week, on the weight tracker sheet.

To record your weight information on a weekly basis, follow these steps:

After you enter the date and weight, the Wt Change column calculates the weight change for that week, based on the previous week's weight and the latest weight.

Weight Tracker Dashboard

To see how things are going, check your progress in the workbook's Dashboard sheet and weight loss goal chart. Are things going in the right direction? Have you hit any plateaus?

The dashboard shows the following information:

  • Your current weight and your target weight
  • Total weight change - the total loss or total gain
  • How much weight remains until you reach your goal.
  • Weight chart has lines that show weekly recorded weight, and your target weight.

BMI Calculation

One version of the Excel Weight Loss Tracker also has a Body Mass Index calculator (BMI calculator). It calculates your current BMI, and target BMI, and shows the healthy weight range for your height.

The BMI chart is used as a lookup table for the ratings for the current BMI and Target BMI. The Minimum and Maximum ideal weight range is calculated from your height, and the Normal range in the BMI table.

Learn more about Adult BMI from the Center for Disease Control and Prevention website. The website cautions:

  • "BMI can be a screening tool, but it does not diagnose the body fatness or health of an individual. To determine if BMI is a health risk, a healthcare provider performs further assessments."

How the Weight Tracker Works

You don't need to read this "How It Works" section, unless you're interested in what's happening in the background of the weight tracker.

If you'd like to know more about the formulas in the workbook, see the explanations and screen shots below. Everything is done with formulas - there are NO macros in the workbook.

Here are the four main worksheets, and the details for each sheet are shown below.

  • AdminLists
  • WeightGoals
  • WeeklyWt
  • Dashboard

AdminLists

The weight tracker workbook has a sheet named AdminLists, where lookup tables and formulas do the background work for the weight tracker. There are 3 sections in the AdminLists sheet:

  • Measurement System
  • Goal Type
  • Chart Title

Measurement System

At the top of the AdminLists sheet, there is a lookup table for the measurement system.

  • Range D3:D4 is named MeasureList, and that list is used in the drop down on the WeightGoals sheet.
  • Cell D6 shows the measurement type that you selected

How to calculate percentage of weight loss in excel

  • Cell F6 has a MATCH formula that finds the selected measurement system in the MeasureList, and returns its location number
    • =IF(MeasureSel="","",MATCH(D6,MeasureList,0))
  • Cell E6 has an INDEX formula that returns the short code for the measurement type - Lbs or Kgs.
    • =IF($F6="","",INDEX(E3:E4,$F6))

Goal Type: Loss or Gain

In the next section of the AdminLists sheet, there is Goal Type (Loss or Gain) information.

  • Cell D8 is named GoalType
  • Range D11:D12 is named TrackType

The Loss/Gain lookup table has descriptions that are used in the workbook's formulas, and the multiplier used in weight change calculations.

How to calculate percentage of weight loss in excel

  • Cell D8 (GoalType) has a formula that checks your current weight and target weight, and calculates if your goal is weight loss or weight gain.
    • =IF(COUNT(WeightGoals!C4:C5)<2, "", IF(WeightGoals!C4> WeightGoals!C5, D11, D12))
  • Cell D14 has a MATCH formula that finds the Goal Type in the TrackType list, and returns its location number
    • =IFERROR(MATCH($D$8,TrackType,0),0)
  • Cells E14 and F14 have INDEX formulas that return the description text. Their IFERROR functions return an empty string for errors.
    • =IFERROR(INDEX(E11:E12, MATCH($D$8,TrackType,0)),"")
    • =IFERROR(INDEX(F11:F12, MATCH($D$8,TrackType,0)),"")
  • Cell G14 has an INDEX formula that returns the multiplier. Its IFERROR function returns a zero for errors.
    • =IFERROR(INDEX(G11:G12, MATCH($D$8,TrackType,0)),0)

Chart Title

The last item on the AdminLists sheet is the formula in cell D16, which calculates the title for the Dashboard and Dashboard Chart.

How to calculate percentage of weight loss in excel

The formula in D16 combines text with the Goal Type and the measurement type.

  • ="Weight " & GoalType & " Tracking - " & E6

WeightGoals

There are 4 formula cells on the sheet named WeightGoals.

Two of the formulas create labels in column B

  • Cell B6 combines text with the measurement type
    • =AdminLists!$E$6 & " per week*"
  • Cell B8 combines the measurement type and goal type:
    • =AdminLists!$E$6 & " to " & AdminLists!E14

How to calculate percentage of weight loss in excel

The other two formulas are in the grey cells, in column C

  • Cell C8 shows the total weight change goal, after the start weight and target weight have been entered
    • =IF(COUNT(C4:C5)<2,0,C4-C5)*TypeMult
  • Cell C9 shows the target date that the weight goal will be reached, after the lbs/kg per week has been entered in C6
    • =IF(C6=0,"",C3+C8/C6*7)

WeeklyWt

The WeeklyWt sheet has formulas in columns D and E. Because this is a named Excel Table, the formulas should automatically fill down when new rows are added to the table.

In the Tgt Wt column, the formula shows the Target Weight from the WeightGoals sheet

=WeightGoals!$C$5

In the Wt Change column, the formula subtracts the weight in the previous row from the weight in the formula row.

=IF(ISTEXT(C1),0,IF(C2="","",C2-C1))

Dashboard

The Dashboard sheet has several formulas, which are explained in the next section:

  • 4 formulas summarize progress (blue - C5, C7, G6, G7):
    • Current Weight
    • Target Weight
    • Weight Change
    • Remaining
  • 2 formulas to show the heading information (yellow - E2, E4):
    • Sheet title
    • Current date
  • 4 formulas to show the selected measurement type - Lbs or Kgs (orange - D6, D7, H6, H7)
  • 1 formula for Hyperlink text (purple - F9)

NOTE: The colour coding is for this screen shot only, and not in the weight tracker workbook.

Current Weight

The Current Weight formula uses the LOOKUP function to get the last number from the Weight column, on the WeeklyWt sheet.

  • =LOOKUP(9.99999999999999E+307, WeightData[Wt])

Target Weight

This formula shows the Target Weight from the WeightGoals sheet

  • =WeightGoals!$C$5

Weight Change

This formula shows the sum of the Weight Change from the WeightGoals sheet

  • =SUM(WeightData[Wt Change])

Remaining

This formula subtracts the Target Weight from the Current Weight, then multiplies by the TypeMult value (1 or -1)

  • =(C6-G6)*TypeMult

Chart and Sheet Title

The chart title is calculated on the AdminLists sheet, and shown at the top of the Dashboard, and as the chart title on the Dashboard.

  • =AdminLists!D16

Current Date

In cell E4, the TODAY function calculates the current date: =TODAY()

Units of Measurement

At the right of each weight, the unit of measurement is shown. The formulas refer to the Measure Selected calculations on the AdminLists sheet

  • =AdminLists!$E$6

Weight Tracker - Stone

If you prefer to track your weight in stone and pounds, there is also a version for that measurement system.

In that Microsoft Excel template, the Weight Goals sheet looks slightly different, and the dashboard shows your weekly progress chart in stone and pounds.

How to calculate percentage of weight loss in excel

On the AdminLists sheet, there is a weight section, where Stone weight (decimal) is formatted to show Stone and Pounds. The formatted weights are shown on the Dashboard.

How do I calculate percentage of weight lost?

If you prefer to calculate your weight loss percentage yourself — or just want to understand how the calculation works — divide the amount of weight lost in pounds or kilograms by your starting weight in the same units, then multiply that by 100.

How do I use Excel to calculate percentage?

The percentage formula in Excel is = Numerator/Denominator (used without multiplication by 100). To convert the output to a percentage, either press “Ctrl+Shift+%” or click “%” on the Home tab's “number” group.

How do you calculate percent by weight?

To determine the weight per cent of a solution, divide the mass of solute by mass of the solution (solute and solvent together) and multiply by 100 to obtain per cent.
