Formulas

Is it possible to recreate this formula in Airtable? Where: i = IRR L = Loan amount F = Points and all other lender fees P = Monthly payment n = Month when the balance is paid in full Bn = Balance in month n This equation can be solved for i only through a series of successive approximations, which must be done by computer. Many calculators will also do it provided that all the values of P are the same. I’m trying to solve for i All items except for i would be supplied via columns inside Airtable

I’m a professional writer, and I have a table where I put all the projects I turn in. On the table, I list how long a project took me (duration) and and how many words it was (#) (along with other factors). What’s the easiest way to create a formula that will give me the time it takes per 100 words? I keep messing up each time I try.

I’ve tinkered with a few ways of doing this, but wanted to get some ideas about the most efficient way. I have this full address string: Street address: 1600 Pennsylvania Ave NW # 15 City: Washington State: DC ZIP Code: 20500-0003 I want to extract the State (in this case, DC). I’ve tried LEFT, RIGHT, MID, etc but nothing seems to zero in on it. Appreciate the help :slightly_smiling_face:

Is there a way to utilize a concatenate formula + Link to Another Record to have a lookup work automatically? I currently have to copy/paste the concatenate result from the formula into the Link to Another Record to get the result via lookup.

Can formulas be used in the free trial version ? Tried to use the multiplication * function but not successful. (error) message coming up.

I have used spreadsheets for a while now but certainly not an expert. I would appreciate any help with formula for a ledger. I enter my info by date. Some entries have debits and credits.I would like the table to calculate new balance for each entry.

Hi everyone! I have done several searches and cannot find exactly what I am trying to do. I am relatively new to all of this and my ADHD brain struggles with all of the technical stuff at first, so I apologize if this is very obvious. I want to simply have a “total hours” field that takes the start and end date/time fields and puts it in hours rounded to the nearest quarter. 2/27/2020 8:00AM to 2/27/2020 9:45 would automatically compute to 1.75. This is for a timesheet :slightly_smiling_face: Thanks!

Hi There! I have a series of tasks with deadlines. The field next to “Deadline” is a countdown titled "Days Left’ with the amount of days left until the task is due. However, I don’t yet have/need deadlines for some of the tasks, so the Deadline field is sometimes empty which results in NaN. The formula I used for “Days Left” is DATETIME_DIFF(Deadline, TODAY(), ‘days’) I’ve tried a few different IF formulas to remove NaN but I keep getting errors. Can anyone help me out here?

Hi there, I am trying to figure out a formula to extract max year for a specific company based on the fields below. Max year should pick a max year for that particular company in the field. I tried using MAX function but it didn’t appear to work, is there a way around this?

This is the data in my cell <ANUZ2B2KI2XTG;ANUZ2B2KI2XTG;23.93+0=23.93;Me;26.12;Ig:r#5:><A20AY8YZ1X41HY;A20AY8YZ1X41HY;23.96+0=23.96;Me;26.12;Ig:r#5:><A2FATTUNY7ADJL;A2FATTUNY7ADJL;23.99+0=23.99;Me;26.12;Ig:r#5:> I am trying to extract the first number which is “23.93” from the cell

Form some reason if I try to multiply or divide I get error however addition and subtraction works fine. What am i doing wrong?

Hi all, couldn’t find this question in existing community chats so thought I’d ask y’all. I am trying to allocate different numeric values for different selections as follows. Strength of Connection: “Very Strong” = 3 Strength of Connection: “Strong” = 2 Strength of Connection: “Weak" = 1 No entry in the Strength of Connection field = 0 Below is the formula I have, and I thought I’ve done this successfully before but its telling me there is an error. IF({Strength of Connection}="Very Strong”,”3”,IF({Strength of Connection}="Strong”,”2”,IF({Strength of Connection}=“Weak”,”1”,”0”))) Thanks for your help!

Hi there, I’m trying to create a “ToDo” base with sub-tasks. I have one table with different “project” in every row, and second table with a few tasks linked to each project. Now, I want to create a rollup record to pull out the percent of the task that is already done. (like if I have 2 tasks for one project, and one is checked, so it’s 50% done…) How can I do it? Thanks!

Hi all. Does Airtable track the date when someone enters data or changes data? We are using it to schedule our content calendar, and I’m trying to create a dashboard showing how long it takes to move a project through several stages, which appear as a drop-down menu. does airtable track the dates somewhere invisible or do users have to manually enter the date they’ve moved to the next step? if so, how do I access this data and set up a formula to show the average number of days between steps over a monthly period? (and then display this in a dashboard) Thanks so much for your help! Joanna

Hi everyone! I’m surprising myself by not being able to figure this out. I swear at one point or another I had been able to pre-fill an airtable form with a field that includes an emoji. For example, I want to pre-fill a single-select {Status} field in a form with a status of “ :calendar: Consult Scheduled” I’ve tried it with the actual emoji character as well as with UTF-8 (hex) encoding (which is what Airtable spits out if I wrap the emoji in the ENCODE_URL_COMPONENT() function - see below). https://airtable.com/shrIXXXXXXXXXXXXX?prefill_Status=%F0%9F%93%86%20Consult%20Scheduled https://airtable.com/shrIXXXXXXXXXXXXX?prefill_Status=📆%20Consult%20Scheduled Neither of these work. Am I barking up the wrong tree? Should I just forget about the emoji? Maybe try a different emoji? :slightly_smiling_face:

Hi all, I am formatting my database to show how long a volunteer has been with us (in order to determine when to give them their 1 year of service, 2 years of service etc), however, the cut-off date each year for our volunteers is 30th April. For example, if a volunteer starts with us on 1/5/2018, at 1/5/2019 the years of service is 0, but at 1/5/2020 it will be 1 year. If a volunteer started with us on 29/4/2018, at 1/5/2019 the years of service is 1, and at 1/5/2020 it will be 2 years. I hope this makes sense! I’d love to know how to formulate this so I can get a ‘1’ or ‘2’ etc. Thanks in advance for your assistance.

I have a table of Customers and a table of memos which are related to the Customer by Account number and in the memos table I put a note each time I speak to the customer with basic info of the date the person I spoke to and what was said. In the Customer table I would like to see the Max (Memos:Date) ie the latest date that I spoke to the customer. At the moment it shows me all the dates as I have used it as a lookup since I cannot find a way to get the Max from a related field as a date. Anybody have any ideas please. I usually use Filemaker and the relationships then are quite transparent so am struggling a bit

I have a table that uses a Date field as its primary key. Each date in use happens to be a Monday and there are records for every single Monday for the past 6+ years. This means that for a given row, the row below it is always 7 days before it. Each row also has a Number field that grows from zero (6 years ago) to 7500 (today), but the growth is nonlinear and varies from week to week. What I want to do is compute a weekly growth rate field. This field would be equal to: (Number today - Number last week) / Number last week In order to do this, I need to reference the number field from one week ago. I’m able to compute the date that I should be looking up, but the result is a formula field and I can’t figure out then how to look up the value I need from the appropriate row. Anyone know a simple way to do this?

Hi, I need some help to do something… 1/I have a column with a price 2/ I have a column with a Single Select option, and a list of discounts (10%,15%,20%,30%) I would like to create a 3rd column, with a formula which gives me the total discounted price, based on the discount which has been selected. So if : Column B has a total of $100 Column C has 10% selected The new column D should show me $90 I don’t know how to create a formula which will calculate the discounted amount based on the selected field. I would be great to have some help on that! :slightly_smiling_face: Thanks, Sébastien

Hi. I want to use barcode scan just like PDA device on werhouse managment system. This means scan barcode from a product and than enter the quantity in the field. For example, I scan a barcode on a stack of 12 pcs and enter 12 pcs (meaning 12 pcs loaded). Problem is, next time when I scan same barcode I cannot enter 12 pcs again in the same field and get automatic sum 24 pcs, 36 and so on but I only can manually insert total result. Is there a formula that can make this happen or another way to achieve this?

Hi Guys, So i have this formula above and i want the result in Currency, like “0€” not “0”. Can anyone help me? IF((Tipo2)=BLANK(),“0”,IF((Tipo2)=“Fatura EU”,“0”,Valor*0.23)) Thanks

Hi - I’m trying to link a chronological set of tasks based on the completion date of a proceeding task. I’ve figured out how to project the due date by taking the start date plus Duration (in days) to get a projected due date, however, i’m stuck how to link this to the next record. For example Task 1 is completed on 1/1/20 Task 2 should have a start date of 1/1/20 plus some duration (say 3 days) and have a projected due date of 1/4/20 Task 3 will then have start date of 1/4/20 and so on… any help would be appreciated!

Hi. I’m new to airtable, and fairly new to formulas. I’m trying to build a formula that looks at the part of an email domain and based on if a specific word exists or not, enter the persona into another field. Example Fields are EMAIL and PERSONA If the EMAIL domain is @usa.company.com and I’m checking if the domain contains “company” I then want to have the PERSONA be “employee”. If it does not contain “company” I want the PERSONA to be “customer” So far this is what I have IF((FIND(“company”,{Email Domain}) >=1)“Employee”, “Customer”)

Hi, I have a base that I copied from an example inventory sheet. I deleted all the records but the first one and then started entering my own. For the first record (from the original copied base) through the 18th record the date shows the wrong month and year (the day may have been correct). The rest of the rows look like they are displaying the right date. How can I fix the first 18 rows to get the correct create date (or since this is not editable is that possible)? Thank you!

I need a formula to calculate ETA (more like Estimated Day of Arrival) for animal breeding purposes. I have a column with number of days bred and a column for the date checked. The average gestation period is 278 days. Is there a formula in which I could use the start date(ex: 9/11/2019), days bred (ex:84), and gestation length (ex:278) to calculate delivery day? Please and Thanks!!!
