EXACT CROSSOVER EXAMPLE
A worked example: nine months of use
These are illustrative prices for the same plan: $15 monthly or $150 paid upfront for one year. The example assumes the annual charge is nonrefundable.
At nine months, monthly billing costs $15 less than the $150 annual charge.
At month 10, the two paths tie at $150.
At 12 months, annual billing costs $30 less than twelve monthly payments.

Same plan. Same terms. Your prices.
Compare like with like.
Use prices for the same service, tier, currency, billing channel, account count, and tax treatment.
Assume no refund.
The annual path is treated as paid upfront and nonrefundable. If your verified terms promise a refund or credit, model that separately instead of assuming it here.
No forecast or recommendation.
The graph does not predict use, renewal, taxes, fees, promotions, future price changes, service quality, cancellation rights, or provider outcomes.
