# Whiskrr Validation Kit: Unit Economics Cost Model
**Block:** COST STRUCTURE | **Priority:** HIGH | **Hypotheses Covered:** H1, H2, H3
---
### Objective
Build a bottom-up cost model with real vendor quotes — not estimates — at 100, 500, and 1,000 active customers. This is the document investors will ask for at every meeting.
---
### Where to Get Real Cost Data
**Cloud infrastructure (get actual quotes):**
- AWS Pricing Calculator — https://calculator.aws.amazon.com — Free; model your expected architecture
- Google Cloud Pricing Calculator — https://cloud.google.com/products/calculator — Free; compare with AWS
- Digital Ocean Pricing — https://digitalocean.com/pricing — Simpler pricing; good for early-stage cost modelling
**AI/LLM API costs (if applicable — public pricing):**
- Anthropic Claude API — https://anthropic.com/pricing — Per-token pricing; model your expected usage
- OpenAI API Pricing — https://openai.com/pricing — Compare GPT-4 vs GPT-3.5 for your use case
- AWS Bedrock Pricing — https://aws.amazon.com/bedrock/pricing — Multiple model options
**Payment processing (actual rates):**
- Stripe Singapore — https://stripe.com/sg/pricing — 3.4% + SGD 0.50 per successful card charge; no monthly fee
- PayNow / FAST — Free for SGD transactions between Singapore bank accounts
- Braintree — https://braintree.com/merchant-tools/fees — Alternative to Stripe; compare rates
**Singapore payroll and HR costs (public benchmarks):**
- MOM Occupational Wage Statistics — https://stats.mom.gov.sg — Official Singapore median wage data by occupation
- MyCareersFuture Salary Range — https://mycareersfuture.gov.sg — Singapore salary benchmarks by role
- CPF Contribution Rates — https://cpf.gov.sg/employer/employer-obligations/employer-contributions-to-cpf — Mandatory employer CPF contribution rates
**SaaS benchmarks for gross margin (public reports):**
- SaaS Capital Gross Margin Benchmarks — https://saas-capital.com — Annual report; B2B SaaS median gross margin: 72%
- OpenView PLG Benchmark Report — https://openviewpartners.com/reports — Free download; CAC and gross margin by ARR band
---
### Model Structure
Build in Google Sheets with 3 tabs: 100, 500, and 1,000 customers. Each tab shows:
- Monthly revenue
- Infrastructure costs (per customer × customer count)
- People costs (founding team time + contractors)
- Tools and SaaS (fixed monthly costs)
- Payment processing fees
- **Gross margin %**
- Monthly burn rate
**Stress test:** What happens if LLM API costs double? What if churn is 10% higher than expected?
---
### Success Criteria
✓ Bottom-up model with real vendor quotes (not estimates)
✓ Gross margin above 60% at 500 customers
✓ Path to cash-flow positive visible at some scale point
✓ Model stress-tested across 3 scenarios
**Time:** 1–2 weeks — 1 week building with real quotes, 1 week stress-testing
*AI-generated guidance. Communities, pricing and benchmarks may change. Only public communities are surfaced. Verify all links before using.*
