海外TECH	DEV Community	The Founder’s Guide to Key Startup Metrics(With Formulas)	https://dev.to/codesphere/the-founders-guide-to-key-startup-metricswith-formulas-5cbm	The Founder s Guide to Key Startup Metrics With Formulas The time when all it took to raise money was some gusto and a smile is gone for the time being If you as a founder want your startup to not just survive but thrive in this bear market you need to be ready with the numbers that validate your business model and product fit Today we re going to explain and calculate key metrics that you should know for your startup Customer Acquisition Cost CAC Customer Lifetime Value CLV Churn Burn Rates and Total Addressable Market TAM Let s get started Customer Acquisition CostCustomer Acquisition Cost CAC measures how much it costs to acquire a singular customer There are two ways to measure it Blended CAC and Paid CAC you re likely going to want to be able to give both to investors Blended CAC is the more general formula It is calculated by taking marketing spend over a period of time and dividing it by the amount of new users during that time period Paid CAC is the acquisition cost excluding organically acquired users This measures exclusively how effective your paid marketing channels are It is calculated by taking marketing spend over a period of time and dividing it by the number of users acquired during that time period through paid channels Additionally you should also be able to calculate the Paid CAC for particular marketing and sales channels that you use This can help you prioritize what channels to utilize Example Let s say in our startup Spent on total marketing efforts on Paid Search on ConferencesAcquired users through paid channels from Paid Search from ConferencesThis would give us the following CAC s Blended CAC users userPaid Cac users userPaid Search CAC users userConferences CAC users user Customer Lifetime ValueCustomer Lifetime Value CLV is an estimate of the present value of the projected future revenue from a customer over the entire lifespan of your relationship with them In plain english it is the total amount of money that you get from the average customer throughout the entire span of your relationship with them Unlike CAC this can be much more difficult to calculate CLV might be asked for in nominal or real terms and ideally should be split up by different segments of your user base Just like CAC The easiest way to calculate CLV is to find the average lifespan of a customer How long they do business with us and the average amount of time that a customer spends per unit of time The average lifespan is equal to the reciprocal of the churn rate more on that later If we are working with nominal CLV then all it takes is multiplying these two numbers together If we are calculating real CLV then we need to factor in a discount rate This is a more complex topic than this discussion warrants but the general idea is that when talking about money we will be receiving in the future we need to factor in the value lost since we are receiving it later on For example having now is better than having years from now because if I had the money today I could buy worth of bonds and be guaranteed even more money a decade from now Example Nominal On average a customer stays with us for years months The average customer spends monthBased on those numbers the nominal CLV months month Example Real I m going to do everything in terms of years to make this simplerOn average a customer stays for years On average a customer spends yearThe discount rate The guaranteed rate of return if we instead bought treasury bonds is So our real Customer Lifetime Value is Depending on what your product is you might have distinct groups of customers that you want to calculate lifetime value for Additionally if you have data on the rate that customers refer new customers you can factor that into your CLV Drop a comment or shoot us an email if you want an explainer on that The validity of your business is based on the ratio between your CLV and CAC Obviously if your acquisition cost is greater than the value each customer is bringing your business model simply is not sustainable The higher your CLV CAC the more opportunity there is for profit and the stronger your business model is Total Addressable Market TAM The other key component to validate your startup s business model is the Total Addressable Market TAM This is the total amount of possible revenue that your company could acquire based on the size of the markets that you meet Note the word possible here is very ambiguous It s very common for founders to overstate their TAM and not get taken seriously as a result A common way to break this issue down is into three submetrics Total Addressable Market TAM Serviceable Available Market SAM Serviceable Obtainable Market SOM Total Addressable Market is the total size of the market you are concerned with Serviceable Available Market is the total size of the portion of the market that would benefit from your services Serviceable Obtainable Market is the portion of the market that you could realistically obtain given existing competition Having these numbers on hand can prove that your startup has room to scaleExample Let s say we are building a digital ordering kiosk for restaurants Our TAM might be the size of the entire restaurant industry However many restaurants are sit down and will always prefer to use waiters Additionally many restaurants don t need digital kiosks because they don t get enough traffic Thus our SAM is the portion of the restaurant industry that is not upscale sit down and have sufficient traffic to warrant getting a digital kiosk But let s say that all major fast food chains build their own kiosk systems Additionally let s say there is a competitor who has already captured the entire west coast but the rest of the country is currently un served Thus our SOM would be the portion of our SAM that is not part of a major chain and is not on the west coast Now let s get to the simpler ones Customer Churn and Retention RateThe Customer Churn rate is the percentage of customers that leave in a given time period It is calculated by taking the amount of customers that leave in a time frame and dividing it by the amount of customers that were there at the beginning of the time frame Similarly the Customer Retention Rate is the percentage of customers that are still customers at the end of a time frame Thus we get that Churn Retention Additionally the customer lifespan is the average amount of time that a customer continues to do business with you It can be calculated by dividing by the churn rate These numbers all show how sticky your product is and are one of the key ways to measure product market fit Example Started with usersOf those users were still using the product by the end of the yearGiven those numbers Customer Retention Rate Customer Churn Rate Customer Lifespan years Revenue Churn and Retention RateThe Revenue Churn Rate is the percentage of your contracts that you lose over a period of time in terms of dollars Unlike Customer Churn this can be positive or negative and is thus a great measure of how well of a value exchange you are doing with your customers This is calculated by taking all the customers that are paying at the start of the time period and then finding the difference between the amount they are spending by the end by the amount they spend at the beginning We then divide that difference by the amount they were spending at the beginningMuch like customer churn we can calculate the revenue retention rate as just the amount they are spending at the end divided by the amount they are spending at the beginning Additionally Revenue Churn Revenue Retention Unlike customer churn revenue churn can also be positive if a lot of your customers increase the amount they are spending over the time period Example Let s say we have customers at the beginning of pay year pay yearOf those customers these are their subscriptions for pay year pay year are no longer doing businessSo this means Our revenue at the beginning of the year was Our revenue for from those customers was Our revenue lost from those customers after a year was Thus our Revenue Churn Rate is Our Retention rate is Those are the main metrics that every founder should sit down to calculate They re not only important to be able to give to investors but to also see if your business is on the right track so that you can correct it if something is wrong Additionally breaking these metrics down by customer segment is one of the best ways to find underserved markets and weak points in your strategy Leave us any questions you have about startup metrics below and we ll try our best to help out Another key challenge that many founders face is managing their devops At Codesphere we re building an all in one development platform to automate all the operations that prevent development teams from actually coding Give us a try	2022-06-28 09:20:51
