I think you did a good job and we are running out of time. Would you like me to redo the calculations using the second equation? Thus, my estimate is that Google spends about $6.12 per user a year in Gmail costs. To calculate marketing cost per user, we divide by 1B users and we get $80M / 1B = $0.08/user per year.Ĭost per user = + + Google’s annual revenue is about $80B, so 10% of that is $8B, and 1% of that is $80M (1% = $8B divided by 10 = $800M divided by 10 = $80M). Most companies in the industry spend 10% of revenue on marketing, so I will use that as a reference. And of that, 1% is spent in Gmail marketing. I know that there are about 1B active users of Gmail based on a recent Techcrunch article I read, so dividing $40M by 1B users results in $40M / 1B users = $0.04/user per year.įor marketing costs, I will assume that about 10% of Google’s total revenue is assigned to marketing. Each with an annual salary of about $200K, so the cost of development per year is 200 X $200K = $40,000K = $40M. So for one user, that results in $0.5 a month, and for a year in X = $6/user per year.įor development costs, my guess is about 200 employees work on Gmail.

I know that AWS charges about $10 a month for running server, storage, and network bandwidth for 20 users. If there is time left, I will redo the estimate using Equation B to compare it to A. I will begin by using Equation A to estimate the cost per user, because it will be faster. Where the first two components can be expanded to, This equation is more accurate because it does not assume that all users consume the same amount of data, which is an oversimplification. = + + Īnother way to estimate the cost per user, would be to separate Gmail users between consumers and business people because business users are likely to consume more data and thus be more expensive. Here’s how I would use this information to estimate the cost per user: Equation A: INTERVIEWEE: The main types of costs I see associated with Gmail are infrastructure costs, which would include servers, storage and data transfers development costs to maintain features and updates and marketing costs.

INTERVIEWEE: And, would the estimation be for all Gmail accounts, or should it include consumers or business or both? INTERVIEWEE: Should I estimate cost per user for the US alone or the world? Do your results make sense? If not, recheck your equation, assumptions and arithmetic. Calculate the result of each component and compute the result. Write down any assumptions next to the components so you don’t forget to explain them clearly to the interviewer. Break down the equation into components.

Consider edge cases or alternate sources of data and write down any facts that you know will help with calculations. This will eliminate any ambiguity of what should be included in your calculations.

The book Cracking the PM Interview by Gayle Laakmann McDowell and Jackie Bavaro provides a good suggestion on how to structure an answer for this type of question. This product management interview question tests whether you are logical, can explain all your assumptions clearly, are organized in your work, and good with numbers. They are looking for a ballpark number, not an accurate number. In estimation questions, interviewers are evaluating your problem-solving and quantitative skills. QuestionĮstimate how much Gmail costs Google per user per year? Answer Structure Last week, we worked on a product estimation question from Lewis Lin’s book PM Interview Questions. We meet weekly to discuss product management interview questions on product design, product launch, strategy, marketing, pricing, and others. We think the best way to prepare, is to work through questions and practice mock interviews as much as possible.
