This is our rolling twelve month forecast template built for mid market SaaS. Most rolling forecasts don't actually roll. Instead, they hardcode a calendar year. This one anchors to your last closed month, so it always shows the trailing twelve actual months plus the next twelve forecast months. Close a month, paste actuals, roll it forward one. And it's driver based. Instead of a single growth rate, you get a full ARR bridge, new expansion, contraction, and churn. Here's where it nets out to today. About twenty eight million dollars in next twelve month revenue, thirty one million exit ARR, Rule of forty, new thirty nine. Now watch what happens when I change an assumption. Say new business picks up. I'll bump bump new ARR growth from one percent to three. Everything downstream recalculates instantly. Exit ARR jumps, next twelve month revenue climbs, and rule of forty moves with it. Same with the scenario toggle. Flip to downside, and hiring and spend pull back too, not just revenue. Your actuals live in a dated ledger the model reads by date with built in checks that flag missing data so it never silently breaks. It's a strong starting point. Connect it to your live data with Aleph, and it updates itself.
