How to assign letter grades with IF or IFS in Excel

Formula (Excel and Google Sheets)

=IFS(B2>=90,"A",B2>=80,"B",B2>=70,"C",B2>=60,"D",TRUE,"F")

Use IFS with the conditions from the highest grade down: =IFS(score>=90,"A",score>=80,"B",score>=70,"C",score>=60,"D",TRUE,"F").

Result on the example
one result per row in C2, filled down to C8
Works in
Excel 2019 and later, including Microsoft 365
Google Sheets
Same formula

The formula is already in C2, filled down to C8. Change any input and the result updates, or edit the formula to experiment.

How it works

IFS checks the conditions in order and returns the result for the first one that is TRUE, so the order matters: checking >=60 first would give every passing score a D. The last pair, TRUE,"F", is the catch-all for everything below 60.

=IFS(B2>=90,"A",B2>=80,"B",B2>=70,"C",B2>=60,"D",TRUE,"F")

Result"A"

  1. B293

    The value in B2.

  2. B2>=90TRUE

    The >= operator tests at least.

  3. B2>=80TRUE

    The >= operator tests at least.

  4. B2>=70TRUE

    The >= operator tests at least.

  5. B2>=60TRUE

    The >= operator tests at least.

  6. IFS(B2>=90,"A",B2>=80,"B",B2>=70,"C",B2>=60,"D",TRUE,"F")"A"

    IFS: Returns the value for the first true test.

    • test1B2>=90TRUE
    • value1"A"
    • test2, value2B2>=80TRUE
    • test2"B"
    • value2B2>=70TRUE
    • test3"C"
    • value3B2>=60TRUE
    • test4"D"
    • value4TRUE
    • test5"F"

In Google Sheets

The same formula works in Google Sheets: =IFS(B2>=90,"A",B2>=80,"B",B2>=70,"C",B2>=60,"D",TRUE,"F"). We ran it in Google Sheets mode on the same data and it returns the same results.

Other ways to do it

Each one was run on the same example sheet.

FormulaResultWhen to use it
=IF(B2>=90,"A",IF(B2>=80,"B",IF(B2>=70,"C",IF(B2>=60,"D","F"))))A, C, B…Nested IFs give the same result and work in every version.
=XLOOKUP(B2,{0,60,70,80,90},{"F","D","C","B","A"},,-1)A, C, B…A lookup on the band starts is easier to change. In a real sheet, keep the bands in cells.

Common mistakes

  • Without the final TRUE,"F", IFS returns #N/A for scores that match no condition.
  • 89.5 gets a B here. If grades should round first, use ROUND(B2,0) in each test.

Try it yourself

Same data, empty answer cell. Your formula is graded instantly, then re-checked on changed data, so a typed-in number won't pass.

Assign letter grades with IF or IFS

In C2, give the letter grade for the score: A for 90 and above, B for 80, C for 70, D for 60, otherwise F. Fill down to C8.

Questions

Is IFS available everywhere?

IFS is in Excel 2019 and later, Microsoft 365 and Google Sheets. Use nested IFs for Excel 2016 and older.

Can I use SWITCH for grades?

SWITCH matches exact values, so it suits categories like "1→Low". For ranges of scores, use IFS or a lookup.
