Prompt to work out unit economics for a D2C brand

What you get: A per-channel unit economics table and the break-even repeat rate. Copy it, fill in the parts in [BRACKETS], and run it in Kriyā or any AI assistant.

The prompt

You are a D2C finance lead. Work out unit economics per order for my brand.

Brand: [BRAND]
Price and cost: [PRICE_COST]
Channels: [CHANNELS]

Give a table per channel (own site, marketplace, quick commerce) with:
1. Price, discounts, GST
2. Product cost, packaging, shipping, payment gateway fee, platform commission
3. Returns and cash-on-delivery losses
4. Marketing cost per order (from CAC and repeat rate)
5. Contribution margin per order in rupees and as a percentage
Then: the three levers that move margin most, and the break-even repeat rate.

Rules:
- Use the India figures listed below and name the source and month next to each one you use.
- If you need a figure that is not listed, write "Assumption:" and give your reasoning instead of a number you cannot source.
- Plain words. Short sections with headings. No filler.

India figures to use (from productgrowth.in/numbers):
- Meta ads in India cost about $1.20 to $3.50 per 1,000 impressions in the first half of 2026 (Sotros Infotech). Source: https://productgrowth.in/numbers/meta-ads-cpm-india/
- Indian payment gateways charge about 2% per domestic transaction on their standard plans in 2026 (Razorpay and Cashfree price lists). Source: https://productgrowth.in/numbers/payment-gateway-charges-india/
- India's quick commerce market is about Rs 1.15 lakh crore (US$ 13 billion) in FY26 (Google and Redseer). Source: https://productgrowth.in/numbers/quick-commerce-market-india/

The numbers this prompt uses

The prompt carries these figures so the answer starts from dated, sourced numbers instead of guesses. Each page shows the source, the month and the history.

Sample answer

Sample answer from Kriyā, 26 October 2026, for the example inputs above. Kept as it came back; links added beside each figure.

The table below uses your price and cost plus a few sourced figures; everything else is an assumption you should replace with your actuals. This runs past my usual length because you asked for a full model.

Inputs I can source

  • Payment gateway: about 2% per domestic transaction, 2026 (Razorpay and Cashfree price lists, productgrowth.in/numbers). Razorpay UPI is 0%, checked Feb 2026 [1]. Cashfree's page quotes UPI AutoPay at ₹5-10 per mandate, Feb 2026 [7].
  • Meta CPM: about $1.20-3.50 per 1,000 impressions, H1 2026 (Sotros Infotech, productgrowth.in/numbers). This is a CPM, not a CAC, so I can't derive CAC from it without a click and conversion rate. source Kriyā's estimate
  • Quick commerce: about ₹1.15 lakh crore market, FY26 (Google and Redseer, productgrowth.in/numbers). It sizes the channel; it says nothing about Zepto's margins. source

Assumptions (replace with your actuals)

  • GST: Assumption: pet food at 18%, with ₹899 as MRP inclusive of GST. Please verify the HSN classification with your CA. your input Kriyā's estimate
  • Own-site discount: Assumption: 10% average. No sourced figure. Kriyā's estimate
  • Packaging and shipping: Assumption: ₹25 packaging; shipping ₹70 on own site, ₹75 FBA-style on Amazon, ₹0 on Zepto (they handle last mile). Kriyā's estimate
  • Commission: Assumption: Amazon about 12% of price including fixed fees; Zepto about 25% trade margin. Check your actual rate cards. Kriyā's estimate
  • Returns and COD: Assumption: own site 4% returns and 30% COD with 8% RTO; Amazon 5% returns; Zepto about 1%. Kriyā's estimate
  • CAC: Assumption: own site ₹350, Amazon ₹120 (ads), Zepto ₹80 (in-app ads). Kriyā's estimate
  • Repeat rate: Assumption: 40% reorder once, so CAC is spread over 1.4 orders. Kriyā's estimate

The own-site loss comes mostly from the CAC and the discount, and it improves with repeat orders. At 4 orders per customer, own-site marketing drops to about ₹88 and contribution turns positive at roughly ₹72. Kriyā's estimate

Three levers that move margin most

  1. Own-site CAC: moving it from ₹350 to ₹200 adds about ₹107 per order at 1.4 orders per customer. Kriyā's estimate
  2. Repeat rate: every extra order per customer cuts the CAC burden, and subscriptions help here.
  3. Pack size and price: a 2-pack bundle spreads shipping, packaging and fixed fees over a larger basket.

Break-even repeat rate (own site)

Contribution before marketing is about ₹160 per order. Break-even needs CAC ÷ orders ≤ ₹160, so ₹350 needs about 2.2 orders per customer, a repeat rate of about 120% (i.e. more than one reorder on average). At ₹200 CAC it falls to about 1.25 orders, a 25% repeat rate. Kriyā's estimate

Next action: send me your real Amazon and Zepto rate cards and last month's blended CAC, and I'll rerun this with actuals.

Beside each figure: source links the number page it comes from, your input means it came from the example inputs, and Kriyā's estimate marks a figure Kriyā worked out or assumed with no source given; check those before you use them. Your own run will differ.
