About this course
A SaaS and subscription metrics course that measures one B2B software company's growth in a spreadsheet, for founders, finance teams and investors. You tag every account's MRR change as new, expansion, contraction or churn and draw the MRR bridge as a waterfall chart, normalise annual plans and setup fees into clean MRR, ARR and ARPA, measure logo churn and revenue churn and annualise them without the ×12 mistake, calculate gross and net revenue retention for a fixed cohort, turn a cohort triangle into a weighted retention curve, work out the fully loaded CAC and its gross-margin payback, compare a capped LTV with CAC for three segments and score the year on the burn multiple, the SaaS quick ratio and the Rule of 40. The first lab is free.
