We are checking out ChartMogul, while their dashboard looks good, we find that the numbers and calculations do not stay consistent. Also, their LTV treats annual subscriptions and monthly subscriptions the same, which I do not believe is correct. What do you use? If you use Chartmogul, are their calculation and numbers to be trusted?

What do you mean they treat them as the same?
To calculate LTV, they convert annual subscriptions to the monthly equivalent (divide by 12), then they apply the same churn rate to all subscriptions. I think this is incorrect. There should be different churn rates applied to the annual and monthly, since annuals are not up for renewal at the same time increments.
LTV should just be the cumulative sum of all the monthly payments grouped by the start date of the subscription. Do you have a screenshot that shows this?
The model that chartmogul uses is MRR/[Monthly Churn Rate] or more simply subscription price* lifetime. So a $10/m subscription and a lifetime of 4 months equates to a $40 LTV.
