Calculate Your Ratio
Pick how much data you have. A single quarter returns your score against the benchmark; a run of quarters shows your trend; projected quarters show where you're headed—with an upper/lower band if your numbers land 10% better or worse than plan. All figures in the same currency, consistently.
Revenue
GTM Spend (Sales & Marketing)—last 4 quarters
R&D Spend—2 quarters (the build window)
Methodology note: GTM = Sales & Marketing expense (GAAP including SBC). R&D = Research & Development expense. Use either GAAP or non-GAAP consistently—don't mix. Benchmarks in the full guide use GAAP. Every ratio needs 6 consecutive quarters for the n-5 R&D lookback, so the timeline carries five quarters of lookback before its first measured point and adds one measured quarter for each period you look back or forward.
