What Is Subscription Pricing?
Subscription pricing charges customers on a recurring schedule for ongoing access to a product or regular deliveries. For Shopify merchants, the price must cover product and shipping costs while leaving enough profit to pay back customer acquisition costs and support repeat orders.
The calculator estimates the effect of a subscriber discount on per-shipment profit, customer lifetime value (LTV), CAC payback, and monthly recurring revenue (MRR). Treat these as planning estimates: actual results also depend on shipment frequency, cancellations, refunds, payment fees, and operating costs.
Subscription Pricing Formulas
Subscription Price = One-Time Price × (1 − Subscription Discount ÷ 100)
Transaction Fee = Subscription Price × Transaction Fee Rate ÷ 100
Profit per Shipment = Subscription Price − Product Cost − Shipping Cost − Transaction Fee
LTV = Profit per Shipment × Average Subscriber Lifespan
LTV:CAC Ratio = LTV ÷ Customer Acquisition Cost
CAC Payback (shipments) = Customer Acquisition Cost ÷ Profit per Shipment
MRR = Subscription Price × Current Active Subscribers
The LTV formula assumes one shipment per month, so average lifespan in months corresponds to the number of shipments. The transaction-fee calculation models a percentage fee; add any fixed per-transaction charges separately when assessing your actual payment costs.
How to Use This Calculator
- One-Time Price — Enter the regular price a customer pays for a single purchase. This is the starting point for calculating the subscriber price.
- Subscription Discount — Enter the percentage discount offered to subscribers compared with the one-time price.
- Product Cost — Enter the cost of goods sold (COGS) for one unit, including what you pay to source or manufacture it.
- Shipping Cost — Enter the shipping cost per subscription shipment that your business covers.
- Transaction Fee — Enter the payment-processing fee as a percentage. Use the rate charged on each transaction and account separately for any fixed fee.
- Average Subscriber Lifespan — Enter the average number of months a customer remains subscribed. This value drives the LTV estimate.
- CAC — Enter your customer acquisition cost: marketing and sales spend divided by the number of new subscribers acquired.
- Current Subscribers — Enter your active subscriber count to estimate monthly recurring revenue.
Step-by-Step Example
Suppose a Shopify store sells a coffee subscription with a regular one-time price of $39.99, offers 15% off, and has 50 active subscribers.
| Calculation | Math | Result |
|---|---|---|
| Subscriber discount | $39.99 × 0.15 = $5.9985 | $6.00 |
| Subscription price | $39.99 − $6.00 | $33.99 |
| Transaction fee | $33.99 × 0.029 = $0.98571 | $0.99 |
| Profit per shipment | $33.99 − $12.00 product cost − $5.00 shipping − $0.99 fee | $16.00 |
| LTV | $16.00 × 8 months | $128.00 |
| LTV:CAC | $128.00 ÷ $25.00 CAC | 5.12:1 |
| CAC payback | $25.00 ÷ $16.00 | 1.56 shipments |
| MRR | $33.99 × 50 subscribers | $1,699.50 |
The MRR figure is subscription revenue, not profit: product costs, shipping, fees, refunds, and other expenses still need to be deducted. The payback estimate also assumes monthly shipments and does not include fixed payment fees.
How to Interpret LTV, Churn, and CAC Payback
Churn is the share of subscribers who cancel during a period. Average lifespan and churn are related: a rough estimate of monthly churn is 1 ÷ average lifespan in months. This assumes a stable cancellation pattern; real cohorts can behave differently, especially after a promotion or first delivery.
A higher LTV:CAC ratio gives you more room to spend on acquiring subscribers, but it does not prove the business is cash-flow positive. CAC is paid before future subscription profits arrive, so CAC payback helps show how long that investment takes to recover. Use the Break-Even Calculator to assess how many orders you need to cover fixed costs, and the Profit Margin Calculator to include expenses beyond the per-shipment inputs here.
For pricing decisions, compare the one-time and subscription offers on profit over the expected customer relationship—not discount size alone. A lower subscriber price can still produce stronger LTV if it improves retention enough to offset the reduced profit per shipment. The Cost-Plus Pricing Calculator can help check whether your base price covers the full cost stack before you set a discount.
Subscription Benchmarks
These are useful starting points, not universal targets; product type, shipment cadence, and acquisition channel affect results.
| Metric | Reference point | What to investigate |
|---|---|---|
| Monthly churn | 5–10% is common for e-commerce subscriptions | Track cancellation by signup cohort and identify when customers leave. |
| Monthly churn | Below 5% is strong; above 15% is a warning sign | Review product fit, delivery timing, onboarding, and cancellation reasons. |
| LTV:CAC | 3:1 or higher is a common target | Below 1:1, acquisition cost exceeds modeled lifetime profit. |
| Subscriber discount | 10–20% is a common range | Test whether added retention or conversion compensates for lower order profit. |
The SBA’s pricing guidance recommends accounting for costs and market conditions when setting prices. Subscription offers also need clear recurring-charge terms: the FTC’s ROSCA overview describes requirements for online negative-option sales, including clear disclosure and informed consent.
6 Tips to Improve Subscription Economics
- Test a 10% discount against a 15% discount. Compare conversion, cancellation, and profit per subscriber over the same period rather than choosing the offer with the highest signup rate.
- Try a prepaid plan for a different cash-flow tradeoff. A quarterly payment can bring revenue forward, but customers may expect a larger discount and the shipment still has to be fulfilled.
- Change delivery timing before cutting the price. If cancellations cluster around a product surplus, test a longer interval or an easy skip option in your subscription app.
- Segment churn by acquisition channel. Compare subscribers from email, organic search, and paid social; a low-cost channel can still deliver poor LTV if its customers cancel quickly.
- Review subscription cancellation reasons monthly. Use Shopify customer records and your subscription app’s cancellation data to distinguish price objections from product, timing, or service problems.
- Test a bundle to raise order value. Add a complementary item and compare the added product cost and shipping weight with the change in profit per shipment.
Frequently Asked Questions
What is subscription pricing?
Subscription pricing is a model where customers pay a recurring fee (monthly, bi-monthly, or quarterly) for regular product deliveries. Shopify merchants commonly offer a 10–20% discount versus the one-time price to encourage signups, trading margin per order for recurring revenue and potentially higher customer lifetime value.
What is a good LTV:CAC ratio for subscriptions?
A healthy LTV:CAC ratio is 3:1 or higher, meaning modeled lifetime profit is at least three times customer acquisition cost. Below 1:1, your estimated lifetime profit does not cover acquisition cost; between those levels, improving retention or reducing acquisition costs may strengthen the economics.
How much discount should I offer for subscriptions?
Many Shopify subscription programs start in the 10–20% range, but the right discount depends on your margins and how customers respond. Test a smaller discount against a deeper one and compare profit over the customer’s lifetime, because a lower discount paired with longer retention can outperform a larger discount with more cancellations.
What is a good churn rate for e-commerce subscriptions?
For e-commerce subscription boxes and replenishment products, 5–10% monthly churn is common, while below 5% is a strong result. Above 15% can signal retention problems; check cancellation timing and customer feedback before changing the price.
How do I calculate customer lifetime value for subscriptions?
- Calculate profit per shipment by subtracting product cost, shipping, and transaction fees from the subscription price.
- Multiply that profit by the average subscriber lifespan in months, assuming one shipment per month.
- Compare the result with CAC; for example, $8 profit per shipment × 10 months = $80 LTV.
Does a high LTV:CAC ratio guarantee that my subscription business is profitable?
No; the ratio compares modeled lifetime profit with acquisition cost but does not include every overhead expense or the timing of cash flows. Include costs such as customer support, returns, software, and fixed payment charges when evaluating total profitability.
