Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

finance-variance-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 27d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

분산 분석 (Variance Analysis)

개요

예산(Budget) 대비 실적(Actual)의 차이를 체계적으로 분석하여 경영 의사결정에 필요한 인사이트를 제공한다. 매출 분산, 비용 분산, 이익 분산을 항목별로 분해하고, 차이의 원인(가격·수량·효율·환율 등)을 파악하여 개선 권고안을 도출한다.

면책 고지: 이 스킬은 AI 보조 분석이며 공인 회계사의 전문 자문을 대체하지 않습니다.

트리거 키워드

분산 분석, 예산 대비 실적, 실적 차이, 원가 분석, 재무 KPI, 수익성 분석, 비용 절감, 예실 분석, 예산 초과, 매출 미달

워크플로우

1단계: 분석 데이터 수집

사용자로부터 다음 데이터 요청:

  • 분석 기간 (월/분기/반기/연간)
  • 항목별 예산(Budget) vs 실적(Actual) 수치
  • 전기 실적 (추세 분석용)
  • 사업부/제품/지역별 세분화 여부

2단계: 전체 분산 요약

총 분산 = 실적 - 예산

  • 유리한 분산 (Favorable, F): 수익은 예산 초과, 비용은 예산 미달
  • 불리한 분산 (Unfavorable, U): 수익은 예산 미달, 비용은 예산 초과
분산 분석 요약표 (예시)

| 항목 | 예산 | 실적 | 분산 | 분산율 | 판정 |
|------|------|------|------|--------|------|
| 매출액 | 100억 | 95억 | -5억 | -5.0% | U |
| 매출원가 | 60억 | 58억 | -2억 | -3.3% | F |
| 매출총이익 | 40억 | 37억 | -3억 | -7.5% | U |
| 판관비 | 20억 | 22억 | +2억 | +10.0% | U |
| 영업이익 | 20억 | 15억 | -5억 | -25.0% | U |

3단계: 매출 분산 분해 (Revenue Variance)

매출 분산 = 가격 분산 + 수량 분산

  • 가격 분산 (Price Variance) = (실제 단가 - 예산 단가) × 실제 판매량

    • 원인: 할인 정책 변경, 경쟁 압력, 제품 믹스 변화
  • 수량 분산 (Volume Variance) = (실제 판매량 - 예산 판매량) × 예산 단가

    • 원인: 시장 수요 변화, 영업 역량, 마케팅 효과

특이요인 체크:

  • 적용 연도의 최저임금·급여 체계 변경 여부
  • 환율 변동 영향 (수출 비중이 있는 경우)
  • 계절성 요인 (추석·설 등 명절 효과)

4단계: 비용 분산 분해 (Cost Variance)

인건비 분산 = 임률 분산 + 능률 분산

  • 임률 분산 = (실제 임금률 - 예산 임금률) × 실제 근로시간
  • 보험료율 변동은 근로자·사업주 부담분과 적용 연도를 분리해 확인
  • 능률 분산 = (실제 근로시간 - 예산 근로시간) × 예산 임금률

4대보험 비용 분산 체크: 적용 연도·보수 기준·가입 대상별 실제 보험료를 확인해 예산과 대조한다. 2026년 참고 수치는 finance-tax-helper/references/2026-rates.md와 공식 보험기관 자료를 확인한다.

제조원가 분산:

  • 재료비 분산: 재료 가격 분산 + 재료 사용량 분산
  • 제조간접비 분산: 예산 대비 고정비·변동비 분리 분석

5단계: KPI 추적 및 벤치마킹

재무 KPI 대시보드:

KPI 예산 실적 전기 업종 평균
매출총이익률
영업이익률
EBITDA 마진
인건비 비율
판관비 비율

업종 평균은 모집단·업종 분류·회계기준·기간이 확인된 공시나 통계가 있을 때만 비교한다. 자료가 없으면 빈칸으로 두고 숫자를 추정하지 않는다.

6단계: 분산 분석 보고서 생성

# [기간] 예산 대비 실적 분산 분석 보고서

## 경영진 요약
- 영업이익 분산: xxx원 (예산 대비 xx% 미달/초과)
- 핵심 원인 Top 3

## 항목별 분산 상세

## 원인 분석 및 책임 부서별 액션

## 수정 전망 (Rolling Forecast)
- 연간 예상 영업이익: xxx원

## 개선 권고안

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
