Annual budgets lock in assumptions that rarely hold up six months later. In volatile markets, where supply chains shift overnight and demand swings wildly, they’re more hindrance than help. CFOs see this firsthand—forecast errors compound, decisions lag, and teams chase ghosts from January.​

Rolling forecasts fix that. They update monthly or quarterly, always looking 12–18 months ahead with fresh data. Driver-based models tie projections to real metrics like customer acquisition costs or churn rates, not static line items. Accuracy improves markedly; studies show revenue forecasts can improve by roughly 14% versus static methods.​

This isn’t just about numbers—it’s about control. Real-time variance analysis spots issues early, so you reallocate resources before problems snowball. Finance leads proactively, not reactively. In chaotic conditions, that agility separates survivors from the rest.​

Shifting requires discipline, not overhauls. Start with your annual budget as a baseline, then layer in monthly updates using FP&A tools. Engage sales and ops for inputs; their ground-level views sharpen the model. Over time, confidence grows, and the old budget fades to a compliance relic.​

Onyx Data Point of View

Annual budgets suited more stable eras; rolling forecasts match today’s volatile reality. They give CFOs a way to steer through uncertainty with data that evolves as fast as markets do.
