“Start with a joke.” My boss used to say when I am nervous about an upcoming presentation. Although, I am not nervous to post this article, I think a joke will always help.
So here it goes:

Now to more serious matters.
VLOOKUP (and other lookup formulas) are very powerful and quite practical. They can fetch you the information you are looking for from a heap of data.
Now that we have seen the power of VLOOKUP thru several posts this week, I want to test your understanding of these formulas by presenting 3 challenges.

Challenge # 1: Price After Discount
We come across this problem quite often. You have a list of discount codes and applicable quantity thresholds. For eg. you may sell an item at $50, but if I buy more than 1 item, you will give a 10% discount. The discount goes up as I purchase more quantity.
Now, given a list of item quantities, how do you calculate the amount payable using lookup formulas? That is our first challenge.
Challenge # 2: Price after accumulated quantity discount
This is essentially same as above formula, but the discounts apply on accumulated quantities bought so far. For eg. I will get first item for 0% discount, 2nd and 3rd items for 10% discount, 4th item for 15% discount … 26th item for 50% discount etc.
Now, given a list of customer names and quantities they bought (in the same order), how do you calculate the amount payable for each transaction?
Challenge # 3: Closest price based on the quantity purchased
This is an interesting challenge. The price after discount is determined based on the quantity bought. For eg. the discount thresholds are 1, 3, 5, 10, 25 etc. Now, given a quantity of items bought, we determine the price by finding the closest threshold to it. So, a quantity of 7 will get the price from threshold 5 as against 10.
Few guidelines on solving these challenges:
Although the above problem might appear simple, the solution is not so straightforward.
- Use a variety of formulas: Do not just rely VLOOKUP. Instead experiment with formulas like SUMIF, COUNTIF, INDEX, MATCH etc. to get results
- Use helper columns: Break down the problem in to several steps and use helper columns to get the results
- Use pen & paper: Write down the logic first, then simulate it in excel using formulas. It clears your mind fast.
- Many solutions exist: Each problem can be solved in several different ways. So once you find a solution, feel free to explore other options
- Share your solutions: Use comments box to share your solutions with us. I am always looking for new ways to solve problems. So teach me…
Solution to the Challenges:
Here is a workbook with one set of solutions for the problems. As I said, many other solutions do exist. So use this workbook as an indication of what is possible.

The 2nd Joke:
It is quite difficult to set an expectation and then meet it. More so with jokes. But do you know that Chandoo.org’s 404 pages show Excel error messages? For example go to http://chandoo.org/wp/missing_file/. Refresh the page to see a different message. 🙂
It is Diwali (the festival of lights) in India this weekend. So I am going to spend time with family, light some fireworks and relax. I wish you a happy Diwali if you celebrate one. Even otherwise, I wish a lot of light and warmth in to your life this year.

I would apply a filter and use function subtotal, with option 9. This way you can see multiple views based on the filter.
hey Chandoo, the solutions you proposed are very efficient, but if I wanted to be fancy I would do it this way .. the references are as your example workbook.
=SUM(INDIRECT("C"&(MATCH(F5,B5:B95)+4)):INDIRECT("C"&(MATCH(F6,B5:B95)+4)))
I like things simple:
=SUMIF(B5:B95,">="&F5,C5:C95)-SUMIF(B5:B95,">"&F6,C5:C95)
use something like: =SUM(OFFSET(B1,0,0,DATEDIF(A1,D1,"d")))
and have D1 be the date that I want to sum to.
In Excel 2003 (and earlier) I'd use an array formula to calculate either with nested if statements (as shown here) or with AND.
{=SUM(IF(B5:B95>F5,IF(B5:B95<F6,C5:C95,0),0))}
Note that I truly made this for BETWEEN the dates, not including the dates
I turned the data set into a table named Dailies.
I named the two limits StartDate and EndDate.
And used an array formula:
{=SUM((Dailies[Date]>=StartDate)*(Dailies[Date]<=EndDate)*Dailies[Sales])}
If I would still be using the old Excel I would do it as follows:
SUMIF($B$5:$B$95,"<="&H6,$C$5:$C$95)-SUMIF($B$5:$B$95,"<"&H5,$C$5:$C$95)
Works as simple as it is.
Regards
=sum(index(c:c,match(startdate,c:c,1)+1):index(c:c,match(enddate,c:c,1))
=sum(index(c:c,match(startdate,b:b,1)+1):index(c:c,match(enddate,b:b,1))
Great examples and thanks to Chandoo. You have simplified my work.
Hi! great tips I have found in your page, have you seen this

[...] I'm not sure I understand your question fully, but have a look at this: Sum of Values Between 2 Dates [Excel Formulas] | Chandoo.org - Learn Microsoft Excel Online [...]
Thank you! Thank you! Thank you!
=SUMIF(A2:A11;">="&B13;B2:B11)-SUMIF(A2:A11;"<"&A11;B2:B11)
awesome... thank yoo Chandoo!
which is most efficient and fast, if all are efficient ?
Thank you for this formula, I've just spent ages trying to find something to work on my data, I knew it would be possible! Don't care if others think there are easier/other ways to do it, you explained it so I understood it and could apply it to what I was doing so I'm happy!
The above said example is awesome for calculating values between dates,
can you pls let know how to calculate sale values if we have 10 sales boys for
ex: 1,rama
2,krishna
3,ashwin
4,naga
5,suresh
how much rama sale value between 1/jan/2015 to 10/jun/15
how much krishna sale value between 10/jan/2015 to 15/july/2015
i think you understood can you pls let me know the formula for how to calculate the sale between diffrent sale man sale value from master data file
Thanks,

Hi
I have a list of people's names in column A, I have a list of dates in column B which records the dates they have been off sick, in column C I have either 1 if it is a full sick day or 0.5 if it is a half day.
What I would like to do is to add up the number of dates a specific person has been off within two dates.
For example, I want to look at my list of names and to find Joe Bloggs (column A), then add up all his sick days (column C). The start date will be in cell E1 and the end date will be in F1.
If this possible using SUMIFS?
List of names are in range A2:A100
List of dates in B2:B100
List of sick days (either 0.5 or 1 in C2:C100
The start date is in cell E2
The end date is in cell F2
Your help would be greatly appreciated.
Yes, with the help of SUMIFS you can have the solution.
Note: you need have an extra col. D2 where you will input Name of the person.
=SUMIFS(C2:C100,A2:A100,D2,C2:C100,">="&E2,C2:C100,"<"&F2)
Col. A Col. B Col. C Col.D Col. E Col. F
Name Date Sales
ABC 28-Jun-11 1 MNO 28-Jun-11 25-Sep-11
XYZ 29-Jun-11 0.5
MNO 30-Jun-11 1
PQR 1-Jul-11 1
Typo ERROR / Correction in formula:

Can you please post the question in the Chandoo.org Forums

Please attach a file so that a specific answer can be delivered.
Thanks for this - it solved the problem that I was having. However can someone please explain to me why the "" needs to be around >= and <= as well as why we need to add & in order for the formula to work? Thanks in advance!
This formula works perfectly as well. Any ideas?: =SUM(INDEX(C5:C95,MATCH(H5,B5:B95,1)):INDEX(C5:C95,MATCH(H6,B5:B95,1)))
ikkeman had posted the same thing.
I am trying to sum total a range of cells between date ranges ie column n has $ amounts column d has the transaction dates ie 1/3/2015 or 25/3/2015 or 25/4/2015 column b has the text saying drp or distribution - reinv
In another cell I am trying to sum or total (in column n) with the value of a range of different dates (column d) that contain different text (column b) ie cell n48 is 50, n65 is 85, n165 is 36
with the dates ie cell d48 is 1/3/2015, d65 is 25/3/2015 and d165 is 25/4/2015
with different text that says drp or distribution - reinv ie cell b48 is drp, b65 is distribution - reinv, b165 is drp
If I wanted to sum the amounts between 1/3/2015 to 31/3/2015 with drp then the total would be 50. Also if I wanted to sum the amounts between 1/4/2015 to 30/4/2015 with drp the sum total would be 36 If I wanted to sum the amounts between 1/3/2015 to 31/3/2015 with drp and distribution - reinv the sum would be 115
What would the formula be for these different questions
hope you can help, it has been driving me nuts and cant work it out
