A B2B sales ROI (Return on Investment) calculation framework.

  • Tasks that involve Positioning and messaging
  • SKILL.md covers Target Agents, ROI Calculation Formulas, Value Quantification Framework and Three-Stage ROI Presentation, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Proposals and quotes

What it does

Roi Calculator is an agent skill from revfactory/harness-100. A B2B sales ROI (Return on Investment) calculation framework. Used for 'sales ROI calculation,' 'TCO analysis,' 'payback period,' 'cost reduction analysis,' and 'value proposition quantification' when writing sales proposals. Note: Financial statement auditing and tax advisory are outside the scope of this skill.

Its SKILL.md is about 1.1k 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 Sales & Support, covering Positioning and messaging, Proposals and quotes and Financial analysis. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Positioning and messaging
  • Tasks that involve Proposals and quotes
  • Tasks that involve Financial analysis

Example prompts

  • “sales ROI calculation,”
  • “TCO analysis,”
  • “payback period,”
  • “/roi-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 (its code samples are markdown).

    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

Roi Calculator loads about 1.1k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 65 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

ROI Calculator — B2B Sales ROI Calculation Framework

A skill that enhances value proposition quantification for proposal-writer and presenter.

Target Agents

  • proposal-writer — Includes persuasive ROI in the proposal
  • presenter — Constructs ROI visualization materials for the presentation

ROI Calculation Formulas

Basic ROI
ROI = (Net Benefit - Investment Cost) / Investment Cost x 100%

Net Benefit = Cost Savings + Revenue Increase + Productivity Gains (Value)
Investment Cost = Adoption Cost + Implementation Cost + Operating Cost + Switching Cost
TCO (Total Cost of Ownership)
TCO = Initial Cost + Operating Cost (N years) + Switching Cost + Hidden Costs

Initial Cost:
  - License/purchase fees
  - Implementation/customization
  - Data migration
  - Training costs

Operating Cost (annual):
  - Subscription/maintenance fees
  - Infrastructure costs
  - Administrative labor costs
  - Upgrade costs

Switching Cost:
  - Existing system termination
  - Parallel operation period costs
  - Productivity loss (learning curve)

Hidden Costs:
  - Downtime costs
  - Security incident risk
  - Regulatory non-compliance penalties
Payback Period
Payback = Total Investment / Monthly Net Benefit

Example:
  Investment: $1M
  Monthly savings: $125K
  Payback = $1M / $125K = 8 months

Value Quantification Framework

Cost Reduction
1. Labor cost savings
   Savings = Automated hours x Hourly rate x Headcount
   Example: 10 hrs/week x $50/hr x 20 people = $40K/month

2. Infrastructure savings
   Savings = (Current infra cost - New infra cost) x 12
   Example: ($50K/mo - $20K/mo) x 12 = $360K/year

3. Error cost reduction
   Savings = Error count x Cost per error x Reduction rate
   Example: 50/month x $1K x 80% = $40K/month
Revenue Growth
1. Conversion rate improvement
   Increase = Current revenue x Conversion rate uplift
   Example: $10M/month x 2% uplift = $200K/month

2. Churn reduction
   Increase = Churned customers x Customer value x Prevention rate
   Example: 100/month x $5K x 30% = $150K/month

3. Upsell/Cross-sell
   Increase = Target customers x Additional purchase rate x Average value
Productivity
1. Time savings
   Value = Hours saved x Hourly rate x Headcount
   Example: 2 hrs/day x $50/hr x 50 people = $110K/month

2. Decision speed
   Value = Opportunity cost x Time reduction

3. Customer service efficiency
   Value = Processing time reduction per case x Case volume x Time value

Three-Stage ROI Presentation

Stage 1: Conservative Scenario
  - Reflects only minimum effects
  - "Even in the worst case, ROI is at least this much"
  - Pre-emptively lowers figures the customer might question

Stage 2: Base Scenario
  - Based on comparable customer cases
  - "ROI most customers experience"
  - Cites specific case studies

Stage 3: Optimistic Scenario
  - When full functionality is utilized
  - "ROI achievable after optimization"
  - Includes long-term value

Boosting ROI Credibility

1. Use customer data
   "Based on your current processing volume of X..."

2. Industry peer case studies
   "Measured over 18 months at a similarly sized manufacturer..."

3. State conservative assumptions
   "We've conservatively assumed a 50% adoption rate"

4. Cite third-party data
   "According to Gartner, the average ROI in this category is X%..."

5. Phased milestones
   "Month 3: Cost savings begin, Month 6: Break-even, Month 12: ROI 200%"
