Same request, same model, once with the skill and once without. Read both and judge for yourself.

“Our habit-tracking app has a $25/month plan and a $240/year plan. Most people pick monthly and cancel by month 3. How should we present pricing so more people choose annual?”

with the skill
**Present annual as a better-value commitment—but investigate month-3 churn before pushing it harder.** Otherwise, you risk turning early cancellations into annual refund requests and unhappy customers. Your annual plan already offers a meaningful discount: - **Monthly:** $25/month, or $300 over 12 months - **Annual:** $240 billed yearly—equivalent to $20/month - **Savings:** $60/year, or 20%, compared with 12 monthly payments Here’s how I’d present and test it. ## 1. Make the comparison effortless Show two options side by side, with annual visually emphasized: | Monthly | Annual | |---|---| | **$25/month** | **$20/month, billed annually** | | Billed monthly | **$240 billed today, then yearly** | | Flexibility to pay month to month | Save $60 vs. 12 monthly payments | | **Choose monthly** | **Choose annual** |

Use a factual annual badge: **“Save 20%.”** Don’t use “Most popular” unless it’s true. Keep the $240 charge prominent—not in a tooltip or tiny footnote. Explain renewal and cancellation terms clearly. **Why it works:** Framing both plans in monthly equivalents makes comparison easier; showing the dollar savings makes the benefit concrete. ## 2. Sell sustained progress, not just cheaper access People buy a habit tracker to achieve an outcome, not to purchase 12 months of software. Connect annual pricing to the long-term job they want done. For example, above the pricing cards: > **Build routines that last.** > Choose monthly for flexibility, or annual for a year of habit tracking at 20% less. If you have features such as long-term trend reports or seasonal goal planning, demonstrate them here. Don’t imply that paying annually guarantees lasting habits. **Why it works:** Jobs-to-be-Done framing gives people a reason to want the year—not merely a reason to accept the discount. ## 3. Offer annual after a real value moment Test an upgrade invitation after users achieve something meaningful: complete their first week, establish a routine, or review their first progress report. Example: > **Keep building on your progress.** > Switch to annual for $240/year—20% less than paying monthly for 12 months. Make any treatment of their existing monthly payment explicit. **Why it works:** Asking after demonstrated value reduces uncertainty. It’s stronger than asking a new user to commit before they know whether the app helps. ## 4. Diagnose the month-3 drop-off Ask departing users whether they: - Didn’t build the habit - Stopped finding the app useful - Found it too expensive - Successfully built the habit and no longer needed tracking Those require different solutions. **Annual billing changes payment timing; it doesn’t necessarily improve retention or customer outcomes.** ## What to test first Start with the transparent pricing comparison above, then test the value-moment upgrade prompt separately. Measure **annual selection and revenue per visitor**, alongside refunds, chargebacks, and 90-day engagement. Don’t declare success just because fewer customers can cancel their payments by month 3.

Make the annual plan’s value obvious—but don’t rely on hiding the upfront cost or making monthly hard to find. Since most customers cancel by month 3, you also need to address why a year feels worth committing to. ### 1. Make the comparison effortless Use two clear cards, with annual visually emphasized and both options easy to select: | **Annual — Best annual value** | **Monthly — More flexibility** | |---|---| | **$240/year, billed upfront** | **$25/month** | | Equivalent to $20/month | Billed monthly | | **Save $60 versus 12 months of monthly billing** | No annual commitment | Put the renewal terms and cancellation policy near the purchase button. Don’t lead with “$20/month” while burying the $240 charge. ### 2. Sell a year of progress, not just a discount Explain what makes the app useful beyond the first few weeks: long-term progress trends, adapting routines, or support for restarting after a lapse—**if your app actually offers those benefits**. A possible headline: > **Build habits that last—with a plan for the whole year.**

Avoid unsupported labels such as “Most popular,” since monthly is currently the more popular option. ### 3. Offer annual when users have experienced value Test the annual offer after a meaningful milestone—for example, completing their first week or seeing their first progress report—not just at signup. For monthly customers, consider crediting a recent monthly payment toward an annual upgrade. State the credit and new billing date clearly. ### 4. Reduce commitment risk honestly If commercially viable, offer a clearly defined trial or refund window. That can make annual easier to choose without pressuring people into a commitment they regret. ### 5. Measure more than annual conversion A/B test the layout, messaging, and offer timing. Track: - Annual purchase rate - Revenue per new customer - Refunds and chargebacks - Engagement at 90 days - Annual renewal rate **The biggest opportunity:** investigate month-3 cancellations alongside the pricing test. If users aren’t getting lasting value, pushing annual harder may improve upfront cash while increasing regret—not build a healthier business.
