Formulas are equations that perform calculations on values in your sheet. All formulas begin with an equal sign (=). You can create a simple formula by using constant and calculation operator. For example, the formula =5+2*3, multiplies two numbers and then adds a number to the result.

When you want to refer to variables instead of constants, you can use cell values, for example, =A1+A2. If you are working with long columns of data, or data that is located in different parts of a sheet or on another sheet, you can use a range —for example, =SUM(A1:A100)/SUM(B1:B100), which represents the division of the sum of the first hundred numbers in column A by the sum of those numbers in column B. When your formula refers to other cells, any time that you change the data in any of the cells Excel recalculates the results automatically.

You can also create a formula by using a function, a predefined formula that simplifies entering calculations.

Equal signs start all formulas.

Excel

Constants, such as numbers or text values, can be entered directly into a formula.

Operators specify the kind of calculation that the formula performs. For example, the ^ (caret) operator raises a number to a power, and the * (asterisk) operator multiplies numbers.

Functions are premade formulas that can be used alone, or as part of a longer formula. Each function has a specific argument syntax.

Cell values let you to reference an Excel cell, instead of the specific value inside the cell so that the contents of the cell can change without the function that refers to the cell having to change.

Enter a formula that refers to values in other cells

  1. In a sheet that contains columns of numbers, click the cell where you want the formula results to appear.
  2. Type an equal sign =
  3. Click the first cell that you want to include in your calculation.
  4. Type an operator. An operator is the kind of calculation that the formula performs. For example, the * (asterisk) operator multiplies numbers. In this example, use the / (forward slash) operator to divide. At this point your formula should look like this:
  5. Click the next cell that you want to include in your calculation. Now your formula should look like this:
  6. Press RETURN.
    The result of the calculation appears in the cell.
    Tip: To quickly apply a formula to the next cells down in the column, double-click the fill handle on the first cell that contains the formula.

Enter a formula that contains a function

  1. In a sheet that contains a range of numbers, click the empty cell where you want the formula results to appear.
  2. Type an equal sign and a function, for example =MIN. MIN finds the smallest number in a range of cells.
  3. Type an opening parenthesis, select the range of cells that you want to include in the formula, and then type a closing parenthesis.
  4. Press RETURN.
    In our example, the MIN function returns 11, the smallest number in cells A1 through C4.

When you enter a formula in a cell, the formula also appears in the formula bar.

In general what you are talking about is 'optimizing' your spreadsheet. You need to find 'bottlenecks' causing the slow performance in your sheet.

Takeaway: You don’t have to live with sluggish workbooks. Try these tricks for a noticeable boost in performance. Most Excel files are small enough not to affect performance, but size isn’t the only thing that can slow things down. Fortunately, you don’t have to know all about multithreads and dual processors to eliminate bad performance. The following tips are easy to implement, so even the most casual users can improve performance when a workbook slows down. Better yet, apply this advice when designing sheets to help avoid sluggish performance altogether. ET MR Macros.docx

Big trouble in little spreadsheet http://chandoo.org/wp/2014/01/17/big-trouble-in-little-spreadsheet/
I pointed out that if you ever find yourself having to switch calculation to Manual, there’s probably something wrong with your spreadsheet.
This prompted one of the participants to come to me for advise regarding restructuring a spreadsheet with that very problem. This analyst had a file with only 6000 rows of data in it, but the file size was something like 35MB, and after each and every change she had to wait at least a minute for the file to recalculate before she could do something else.
It turns out there were two problems with her files that were easy to resolve. ET MR Macros.docx

Circular References: Calculation, Detection, Control and Removalhttps://fastexcel.wordpress.com/2015/09/14/excel-circular-references-calculation-detection-control-and-removal/
Excel circular references occur either when a formula refers to itself or when a chain of formulas links back to it’s starting point.
Most of the time circular references are created by mistake (unintended circular references) and should be corrected. They can also be used to solve iterative or goal-seeking problems in Finance and Engineering.

Handle Volatile Functions like they are dynamite http://chandoo.org/wp/2014/03/03/handle-volatile-functions-like-they-are-dynamite/
If you’re building large models, then you may want to use volatile functions – including OFFSET(), INDIRECT(), and TODAY() – with caution, because unless you know what you are doing, they *might* slow Excel down to the point that data entry is sluggish, if not downright tedious.
In fact, you *might* want to consider getting out of the habit of using these functions at all if there are alternatives, and you might want to replace volatile functions in your existing models with non-volatile alternatives…I have reduced recalculation time in large models from minutes to milliseconds by doing just that!
