Petra - FP&A Analyst AI Skill

Real example

You

We're thinking of a 10% price increase. ARR is $4.0M, churn might go from 8% to 11%. Model it.

SCENARIO ANALYSIS - 10% price increase

BASE UPSIDE STRESS
Annual churn: 8% 9% 11%
Price change: 0% +10% +10%
Year-end ARR: $3.68M $4.00M $3.92M

How it works: $4.0M x (1 + price change) x (1 - churn). New sales are left out to isolate the price effect.

Narrative
Base: no change, ARR drifts to $3.68M on today's churn.
Upside: the increase sticks and churn barely moves, +$324k vs. base.
Stress: churn hits 11% and you still end $236k above base.

Decision trigger: the increase pays off unless churn passes about 16%. That's where 1.1 x (1 - churn) drops below 0.92.

Which customer segment is most price-sensitive? I'd test there first.

Flip the FP&A ratio - rolling forecasts, variance analysis, and commentary that turns numbers into decisions.

How it works

Ask Petra something hard.

📎 fpa-analyst-skill-claude.skillLOADED ✓

We missed Q3 EBITDA by 12% and the board wants the variance analysis by Friday. Walk me through it.

CLAUDE · AS PETRA, FP&A ANALYST Build the bridge: budget EBITDA on the left, actuals on the right, decomposed into volume, price/mix, FX if you carry it, then opex by driver. Separate one-offs - the severance, the audit true-up - from run-rate misses: boards forgive one-offs and punish run-rate surprises. Your 12% will collapse into three or four bars, not twelve. Close with the reforecast implication: which Q4 guidance still survives. Send the TB and budget file - I'll draft the commentary in board language.

What you're actually buying

Drop Petra into Claude and get a fully configured FP&A analyst who builds rolling forecasts, runs variance analysis, models budget scenarios, and writes the financial commentary that turns your numbers into decisions.

FP&A professionals spend 70% of their time gathering and preparing data and 30% doing actual analysis. Petra reverses that ratio - handling the structured narrative and commentary tasks so analysts spend time on the judgment and interpretation work that actually requires a human.

What you get

→ Rolling forecast narratives - current forecast explained against prior period, prior forecast, and budget with structured variance attribution
→ Variance analysis - budget vs actual broken down into volume, price, mix, and timing components with plain-English explanations
→ Scenario modelling - base, upside, and stress cases documented with sensitivity on key revenue and cost drivers
→ Budget commentary - P&L line-by-line explanations for management accounts that tell the business story behind each number
→ KPI narrative - what each metric is, what it is telling you this period, and what the trend implies for the business going forward
→ Finance business partner communications - financial performance data translated into operational recommendations for business unit leaders
