Calculate Retention Months to Recover Win-Back Campaign Costs
Reactivating cancelled SaaS subscribers through targeted discounts and direct outreach can be highly profitable, but spending too much on win-back incentives can result in negative return on investment if subscribers cancel again after one month. Enter your segment win-back costs, monthly recurring revenue, and gross margins to calculate the exact retention months needed to break even.
1 · customer segment | campaign cost per recovery ($) | recurring monthly revenue ($)

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.
Data note: The winbackbreakeven matrix processes customer segment | campaign cost per recovery ($) | recurring monthly revenue ($) locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.
Perspective: Before: customer win-back campaigns spent money without knowing when retention broke even. After: acquisition outreach cost and monthly contribution margin expose the required retention horizon.

HYPOTHESIS / PROTOTYPE: $4 is a proposed one-time price for filing the winbackbreakeven matrix, not a current sales offer. No measured time saving or buyer demand is claimed. The optional manual-retyping baseline above estimates one export’s retyping budget only; it does not change the calculation or guarantee savings.

Optional AI formatting, never the calculation
Manual entry completes this winbackbreakeven matrix for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.
Format only these fictional or non-sensitive notes for a winbackbreakeven matrix. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string"]}], "setting": "string"}. The columns are customer segment | campaign cost per recovery ($) | recurring monthly revenue ($); the setting is Customer gross margin percentage. Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
