AI Budget Planner - Allocate Spend Across Use Cases

Meet Daniel Liu. VP Product at a 100-person SaaS. "I have $180K annual budget and 6 AI features competing for it. How do I allocate without screwing the team that needs it most?"

🔥 Last year I gave it all to the chatbot. Search team got nothing and built a worse experience that hurt retention.

The story

AI budget allocation is product strategy, not finance. The wrong allocation produces predictable failures - the loud feature gets funded, the high-ROI utility feature starves. Six months later: the loud feature isn't moving metrics, the utility one is degraded, and you can't tell why.

Daniel's 6 features compete for $180K. The chatbot gets the loudest meeting attention but moves retention 0.5%. Search powers 40% of traffic but is 'just retrieval.' Recommendations drives 12% of revenue but is 'old AI.' The framework here is to score each feature on ROI (not enthusiasm), allocate by priority, and reserve buffer for the highest-leverage feature to grow.

This calc takes your annual budget, your features list with ROI scores, and produces a defensible allocation. Plus reserves a 15-20% buffer for the inevitable optimization needs.

📊 CALCULATOR AT A GLANCE

🎛 Inputs you control

Each input shapes the cost. Click an input on the calculator to set it — explanations below match the live calculator field by field.

Your use cases — Each AI-powered feature/workflow to budget, with its own model + volume.
How to choose: Add one row per workflow; load a preset to start, then edit per-row model, tokens, and requests.
Preset starting point — A template portfolio (startup, enterprise, agent-heavy) that pre-fills typical use cases.
How to choose: Pick the closest profile then adjust rows to your actual apps.
Monthly budget ceiling — The monthly spend cap to compare your portfolio against.
How to choose: Enter your approved monthly AI budget; alerts flag when projected spend exceeds it.

About this calculator: AI Budget Planner - Allocate Spend Across Use Cases

Split your annual AI budget across product features by ROI priority. Avoid overspending on shiny features at the cost of high-ROI utility ones.

Reading your result

Your top-priority feature should get 30-40% of allocatable budget. Concentrating budget on the highest-ROI feature beats spreading it. Diminishing returns kick in around 50%+.

Mid-priority features get equal-ish slices. 3 features at 18-22% each is typical for the middle tier.

Low-priority features should be at zero or under-explore allocation. If a feature can't justify >5% of budget, it shouldn't be funded with company-wide AI dollars - let the team find another path.

The 15-20% buffer is non-negotiable. Vendor pricing changes 30-50% per year. New high-ROI feature requests come monthly. Without buffer, every surprise becomes a fight over existing allocations.

What "good" looks like:
  • Healthy concentration: Top feature 30-40%, top 3 at 70-80%, buffer 15-20%
  • Over-concentrated: Top feature 50%+ - consider splitting top into sub-features
  • Spread too thin: No feature above 20% - try concentrating on best 2-3
  • No buffer: 100% allocated - fragile, will require painful re-allocation mid-year

Three real scenarios

Same calculator, three different team sizes. Click a tab to see how the numbers shift.

$12,750 / month ≈ $180,000 / year

Daniel's situation. $180K total → $27K buffer → $153K allocatable. Top feature gets $54K (35%), 3 mid features get $22K each ($66K total), 2 low features get $16.5K each ($33K total). 6 features properly funded with buffer for surprises.

Healthy range: Top: ~$54K, mid 3: ~$22K each, low 2: ~$10K each

Best fit for "cost":

  1. Highest-ROI feature gets the optimization investment Concentrate engineering
  2. Cheap-tier model for low-priority features Stretch dollars further

Don't optimize the lowest-funded feature - concentrate optimization on the top 1-2. They're where the savings move the needle.

Use cases

$16,667 / month ≈ $250,000 / year

Going into board with 5 AI initiatives. $250K budget. 20% buffer ($50K) signals discipline. Top feature 40% of allocatable shows you have a clear bet. Mid 3 at ~17% each. One low at 5% (kill candidate).

3 years of pricing history

Why this matters: pricing for major vendors has dropped 40-90% in the last 24 months. A budget set 12 months ago is probably wrong by 30%+.
