ROAS Calculator (Ads)

Evaluate ad ROAS against ecommerce margin reality, not just attributed revenue. Use when teams need a fast scale/hold/cut decision on paid traffic.

Security Scan

This is an instruction-only ROAS calculator that is internally consistent with its stated purpose and requests no credentials, installs, or unexpected access.

Purpose & Capability

The name/description match the instructions: the skill asks for ad spend, attributed revenue, cost and refund parameters and computes adjusted ROAS and break-even — all relevant to the stated goal.

Instruction Scope

SKILL.md restricts operations to taking the listed numeric inputs and producing a assumptions table, ROAS summary, break-even comparison, and a recommendation. There are no instructions to read system files, environment variables, or transmit data to external endpoints.

Install Mechanism

No install spec and no code files are provided (instruction-only), so nothing is written to disk or fetched during install.

Credentials

The skill declares no required environment variables, credentials, or config paths — proportionate for a calculation/reporting helper.

Persistence & Privilege

always is false and the skill is user-invocable. Autonomous invocation is allowed (platform default) but there are no additional privileges or persistent installs requested by the skill.

Assessment

This skill appears low-risk and coherent. Before using, do not paste sensitive account credentials or PII into the inputs; verify units (currency, percentages) and any default assumptions the skill uses; test the calculator with known examples to confirm the math; and if you later connect it to live data or pipelines, ensure that integration only supplies the minimum needed data and is subject to your normal security reviews.

ROAS 看起来高，不代表这笔广告真的值得放大。

解决的问题

很多团队看到广告回收就会加预算，但忽略了：

• 折扣、退款、物流和手续费会侵蚀可保留收入；
• 平台归因很好看，不等于真实利润好看；
• 一条广告 ROAS 够不够，不是看行业平均，而是看你的 unit economics。

这个 skill 的目标是： 把 ROAS 放回真实电商利润语境里，给出 scale / hold / cut 的判断。

何时使用

• 准备放大预算前；
• 广告表现看起来不错，但利润不确定；
• 团队需要统一 break-even ROAS 口径。

输入要求

• 广告花费
• 归因收入
• 毛利 / 成本结构
• 折扣与优惠
• 退款率 / 退货影响
• 可选：渠道费、创意成本、客服成本

工作流

1. 计算名义 ROAS。
2. 根据利润结构估算 break-even ROAS。
3. 根据退款和折扣校正有效收入。
4. 给出是否可放量的建议。

输出格式

1. 假设表
2. ROAS 结果
3. Break-even 对照
4. 建议动作

质量标准

• 不只汇报 ROAS 数字，要解释够不够。
• 明确指出归因和真实利润的差距。
• 输出要能直接支持预算决策。
• 清楚标注估算项。
