The average RevOps team spends 40+ hours per month calculating commissions.

Spreadsheets break. Formulas have errors. Reps dispute their payouts. And when comp plans change mid-quarter, everything needs to be rebuilt from scratch.

Meanwhile, your sales team loses trust every time their commission is wrong—even by a few dollars.

Claude Code offers a better way. Its 200K context window can hold your entire comp plan, deal data, and calculation logic in a single session. Here's how to build a commission calculator that handles real-world complexity.

The Commission Calculation Problem

Before we solve it, let's acknowledge why it's hard:

Complexity Layers

A "simple" commission structure often includes:

  • Base rates that vary by product, region, or segment
  • Tiers that accelerate as reps hit quota thresholds
  • Splits between AEs, SDRs, SEs, and CSMs
  • SPIFs for strategic initiatives (new product push, multi-year deals)
  • Clawbacks for churned customers
  • Overrides for managers on team deals
  • Caps and floors on certain deal types
  • Pro-ration for mid-quarter hires or territory changes

The Spreadsheet Trap

Most teams start with Excel. By month 6, you have:

Commission_Calculator_v14_FINAL_FINAL_v2_JohnFix_ACTUALLY_FINAL.xlsx

With nested IFs that no one understands:

=IF(AND(B2="Enterprise",C2>50000,D2="New"),
IF(E2>1,G2*0.12*1.15,G2*0.12),
IF(AND(B2="Mid-Market",C2>25000),
IF(F2="SPIF",G2*0.10*1.25,G2*0.10),
G2*0.08))

When something breaks—and it will—good luck debugging that.

The Trust Problem

57% of sales reps have received an incorrect commission statement (Xactly). When reps don't trust their comp, they:

  • Spend time manually verifying every deal
  • Lose motivation during payout disputes
  • Leave for companies with "cleaner" comp plans

Trust in compensation is trust in leadership.

The Claude Code Solution

Claude Code's strengths align perfectly with commission calculation:

  1. Natural language rules - Describe your comp plan in English, not formulas
  2. 200K context - Hold the entire comp plan + all deals in one session
  3. Explainable logic - Ask "why did this deal pay $X?" and get a real answer
  4. Adaptable - Change the plan mid-quarter without rebuilding

Step 1: Document Your Comp Plan

Instead of nested formulas, describe your plan clearly:

# Sales Commission Plan - Q1 2026

## Base Rates

### Account Executives
- New Business: 10% of first-year ACV
- Expansion: 8% of expansion ACV
- Renewal: 3% of renewal ACV

### SDRs
- Qualified Meeting: $100 per SAL
- Opportunity Created: $250 per SQL that converts to opportunity
- Deal Credit: 2% of won ACV (capped at $2,000 per deal)

### Sales Engineers
- Technical Win: $500 per closed-won where SE was primary
- Deal Credit: 3% of won ACV for complex deals (>$50K)

## Tier Accelerators

| Quota Attainment | Multiplier |
|------------------|------------|
| 0-80% | 1.0x |
| 80-100% | 1.15x |
| 100-120% | 1.30x |
| 120%+ | 1.50x |

## SPIFs (Q1)
- New product (DataSync): Additional 2% on any deal including DataSync
- Multi-year: Additional 5% for 2+ year commitments
- Competitive displacement: Additional $1,000 for wins against Competitor X

## Splits
- SDR + AE on same deal: SDR gets meeting bonus + 2% deal credit; AE gets standard rate
- AE + SE on complex deal: SE gets technical win bonus; AE gets standard rate
- Two AEs on deal: Split based on documented territory/role agreement

## Clawbacks
- Customer churns within 6 months: 100% clawback
- Customer churns 6-12 months: 50% clawback
- Downgrade within 12 months: Clawback on difference

## Caps and Floors
- No cap on accelerated earnings
- Minimum $500 payout per closed-won deal (protects small deal motivation)
- Manager override: 5% of team deals, capped at $50K/quarter

Step 2: Build the Calculator

Feed your comp plan to Claude Code:

You are a commission calculator for a B2B SaaS sales team. 

COMMISSION PLAN:
[Paste your entire comp plan document]

CALCULATION RULES:
1. Apply base rates first
2. Apply tier multipliers based on current quota attainment
3. Apply applicable SPIFs
4. Calculate splits according to deal roles
5. Check for clawbacks on previously paid commissions
6. Apply caps/floors
7. Show your work at each step

For each deal, output:
- Gross commission before modifiers
- Applicable tier multiplier
- SPIFs applied
- Split breakdown (if multiple parties)
- Final commission per person
- Reasoning for each decision

If anything is ambiguous, flag it for human review rather than guessing.

Step 3: Process Deals

async function calculateCommission(deal, repProfile) {
const prompt = `
Calculate commission for this deal:

DEAL:
- Company: ${deal.company}
- ACV: $${deal.acv}
- Type: ${deal.type} (New/Expansion/Renewal)
- Products: ${deal.products.join(', ')}
- Contract term: ${deal.termMonths} months
- Close date: ${deal.closeDate}
- Displaced competitor: ${deal.displacedCompetitor || 'None'}

REP:
- Name: ${repProfile.name}
- Role: ${repProfile.role}
- Quota: $${repProfile.quota}
- YTD Closed: $${repProfile.ytdClosed}
- Current attainment: ${repProfile.attainment}%

OTHER PARTIES ON DEAL:
${deal.splits.map(s => `- ${s.name} (${s.role}): ${s.contribution}`).join('\n')}

Show all calculations step by step.
`;

return await claude.calculate(prompt);
}

Step 4: Handle Edge Cases

Claude Code shines on the weird stuff:

EDGE CASE HANDLING:

Deal: Multi-year with mid-contract expansion
- Customer signed 3-year deal in January ($100K ACV)
- Expanded in March (+$25K ACV, same rep)

Question: How do we calculate the expansion commission?

REASONING:
1. Original deal: 3-year, so multi-year SPIF applies (10% + 5% = 15%)
2. Expansion: Same contract term, inherits multi-year status
3. Expansion rate: 8% base + 5% multi-year = 13%
4. Rep attainment: Now at 125% with original deal
5. Tier multiplier: 1.50x applies to expansion

CALCULATION:
$25,000 × 13% × 1.50x = $4,875

FLAG: Verify if expansion should inherit multi-year SPIF
(policy may differ by team).

Practical Workflows

Monthly Commission Run

async function runMonthlyCommissions(month, year) {
// Get all closed deals
const deals = await crm.getClosedDeals({ month, year });

// Get all rep profiles
const reps = await getRepProfiles();

// Calculate each deal
const commissions = [];
for (const deal of deals) {
const calc = await calculateCommission(deal, reps[deal.ownerId]);
commissions.push({
deal: deal,
calculation: calc,
breakdown: parseBreakdown(calc)
});
}

// Check for clawbacks
const clawbacks = await checkClawbacks(month, year);

// Generate report
return {
totalPayout: sum(commissions.map(c => c.breakdown.finalAmount)),
byRep: groupByRep(commissions),
clawbacks: clawbacks,
flaggedForReview: commissions.filter(c => c.breakdown.hasFlags)
};
}

Rep Self-Service

Let reps verify their own commissions:

async function repCommissionQuery(repId, question) {
const repProfile = await getRepProfile(repId);
const recentDeals = await getRecentDeals(repId);
const commissionHistory = await getCommissionHistory(repId);

const prompt = `
A sales rep is asking about their commission.

REP PROFILE:
${JSON.stringify(repProfile)}

RECENT DEALS:
${JSON.stringify(recentDeals)}

COMMISSION HISTORY (Last 3 months):
${JSON.stringify(commissionHistory)}

QUESTION:
${question}

Answer clearly, show relevant calculations, reference
specific deals and comp plan provisions.
`;

return await claude.answer(prompt);
}

Example queries:

  • "Why did the Acme deal only pay $2,400?"
  • "What's my commission if I close the pending BigCorp deal?"
  • "Am I on track for the 120% accelerator this quarter?"

Plan Modeling

Model comp plan changes before implementing:

async function modelPlanChange(proposedChange, historicalDeals) {
const prompt = `
We're considering this comp plan change:
"${proposedChange}"

Analyze the impact using last quarter's deals:
${JSON.stringify(historicalDeals)}

Show:
1. Total payout difference (old plan vs new)
2. Impact per rep
3. Which deal types are affected most
4. Potential unintended consequences
5. Recommendation
`;

return await claude.analyze(prompt);
}

Example: "What if we increase the new business rate from 10% to 12% but cap it at 110% attainment?"

Advanced Patterns

Multi-Currency Handling

CURRENCY RULES:
- All commissions paid in USD
- Deals closed in other currencies: use exchange rate at close date
- Exchange rate source: Company treasury rates (monthly)

EXAMPLE:
Deal closed in EUR: €50,000
Close date: February 15, 2026
Treasury rate (Feb 2026): 1.08 EUR/USD
USD equivalent: $54,000

Commission calculated on $54,000 USD value.

Territory Changes Mid-Quarter

TERRITORY CHANGE HANDLING:

Rep A had Territory X from Jan 1 - Feb 15
Rep B took over Territory X on Feb 16

Deal in Territory X closed March 10

RULE:
- If deal was in pipeline before transfer:
Original rep (A) gets full commission
- If deal entered pipeline after transfer:
New rep (B) gets full commission
- If deal was in active stage during transfer:
Split 50/50 or per documented agreement

This deal entered pipeline Jan 25, so Rep A gets full commission.

Clawback Automation

async function processClawbacks() {
// Find churned customers
const churns = await crm.getChurns({ lookbackMonths: 12 });

for (const churn of churns) {
// Find original commission
const originalCommission = await findCommission(churn.dealId);

// Calculate clawback
const monthsSinceDeal = monthsBetween(
originalCommission.closeDate,
churn.churnDate
);

let clawbackRate;
if (monthsSinceDeal <= 6) clawbackRate = 1.0;
else if (monthsSinceDeal <= 12) clawbackRate = 0.5;
else clawbackRate = 0;

if (clawbackRate > 0) {
await createClawback({
repId: originalCommission.repId,
dealId: churn.dealId,
amount: originalCommission.amount * clawbackRate,
reason: `Customer churned at ${monthsSinceDeal} months`
});
}
}
}

Results to Expect

Teams using AI-powered commission calculation typically see:

MetricBeforeAfterImpact
Calculation time40+ hrs/month2-4 hrs/month90% reduction
Error rate8-12%<1%90%+ fewer disputes
Rep trust score62%91%47% improvement
Time to resolve disputes3-5 daysSame day80% faster
Plan change implementation2-3 weeks1-2 days85% faster

The biggest win: reps stop wasting mental energy worrying about comp. That energy goes back into selling.

Getting Started

  1. Document your current plan - Write it in plain English, not spreadsheet formulas
