Weekly plans use the weeks per year you set; monthly figures are the yearly cost divided by 12. Each plan is rounded first and totals add the rounded plans. Processing stays on your device.\n\n### Inputs and settings\n\nText input: Subscription plans.\n\nExample or placeholder shown in the interface (not a validated fixture):\n\n```text\nplan;price;frequency;trial months\nStreaming;15.49;monthly\nCloud storage;99.99;yearly\nGym;12.00;weekly\nNews;5.00;monthly;1\n```\n\nOne plan per line with a header row: plan, price, frequency and optional trial months. Frequencies include weekly, every two weeks, monthly, quarterly and yearly. Write prices without currency symbols. Up to 200,000 characters. Review the settings before running.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `currency` | Currency code | text | \"USD\" | |\n| `precision` | Currency decimal places | select | \"2\" | Allowed: 0, 1, 2, 3, 4, 5, 6 |\n| `rounding` | Rounding | select | \"half-up\" | Allowed: half-up, half-even, half-down, down, up, floor, ceiling |\n| `weeksPerYear` | Weeks per year | text | \"52\" | |\n| `daysPerYear` | Days per year | text | \"365\" | |\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nUp to 200 plans and 200,000 characters. Prices up to 1,000,000,000,000 with up to the selected currency decimal places (0 to 6). Free trials from 0 to 12 months. Weeks per year from 52 to 53 and days per year from 365 to 366, each with up to six decimal places. Calculated on your device. Download a JSON report and CSV files.\n\nThis describes intended requirements.

These period counts match the pay period table in IRS Publication 15-T (2026). A 12.00 weekly gym plan costs 624.00 a year and 52.00 a month.
