What it does

Cap Rate Calculator is an agent skill from revfactory/harness-100. 부동산 수익률 계산기. profitability-analyst 에이전트가 투자 수익성을 정량 분석할 때 참조하는 공식과 모델. 'Cap Rate', '수익률 분석', 'DCF', '현금흐름 분석' 요청 시 사용. 단, 세무 상담이나 대출 심사는 범위 밖.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Financial modeling. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Financial modeling

Example prompts

  • “Cap Rate”
  • “/cap-rate-calculator”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cap Rate Calculator loads about 676 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 212 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~676

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Cap Rate Calculator — 부동산 수익률 계산기

profitability-analyst 에이전트의 투자 수익성 분석 역량 강화.

핵심 수익률 지표

Cap Rate (자본환원율)
Cap Rate = NOI / 매입가격 × 100

NOI (Net Operating Income) = 총 임대수입 - 운영비용
운영비용 = 관리비 + 수선유지비 + 보험 + 세금 + 공실손실

예시:
  매입가격: ₩10억
  연간 임대수입: ₩7,200만 (월 ₩600만)
  운영비용: ₩1,200만
  NOI: ₩6,000만
  Cap Rate: 6,000 / 100,000 × 100 = 6.0%
Cap Rate 벤치마크 (한국 기준)
부동산 유형Cap Rate 범위리스크
오피스 (강남)3.5~4.5%낮음
오피스 (기타)4.5~6.0%중간
리테일 (상가)4.0~7.0%중간
주거 (아파트)2.0~4.0%낮음
물류/창고5.0~7.0%중간
오피스텔3.5~5.5%중간
임대수익률 (Gross Yield vs Net Yield)
Gross Yield = 연간 총 임대수입 / 매입가격 × 100
Net Yield = NOI / 매입가격 × 100

통상 Net Yield ≈ Gross Yield × 0.7~0.85
(운영비율 15~30%)

현금흐름 분석 (Cash Flow)

레버리지 수익률
Cash-on-Cash Return = 세전 현금흐름 / 자기자본 × 100

세전 현금흐름 = NOI - 연간 대출 원리금

예시:
  매입가격: ₩10억 (LTV 60% = 대출 ₩6억)
  자기자본: ₩4억
  NOI: ₩6,000만
  연간 원리금: ₩3,600만 (3.5%, 30년)
  세전 현금흐름: ₩2,400만
  Cash-on-Cash: 2,400 / 40,000 × 100 = 6.0%

(=) NOI₩480만₩5,760만
(-) 대출 원리금-₩300만-₩3,600만
(=) 세전 현금흐름₩180만₩2,160만

DCF (현금흐름 할인법)

부동산 가치 = Σ [NOI_t / (1+r)^t] + 잔존가치 / (1+r)^n

잔존가치 = NOI_{n+1} / Exit Cap Rate

변수:
  r: 할인율 (보통 8~12%)
  n: 보유 기간 (보통 5~10년)
  Exit Cap Rate: 매각 시 Cap Rate (보통 +0.5% 가산)

NOI 성장률 가정:
  보수적: 연 1~2% (물가 상승률)
  기본: 연 2~3% (임대료 인상)
  낙관적: 연 3~5% (지역 성장)
