SleekRank renders whatever the data row carries, including worked examples. For interactive input where readers type their current balance, current rate, and new rate, ship an Alpine component on the base page that runs the break-even formula. SleekRank handles the static SEO surface; the widget handles ad-hoc input.

Break-even is closing costs divided by monthly savings. Store both inputs as columns and let the worked examples array carry pre-computed break-even months at representative balances. Readers see consistent math; editors update one column when closing-cost ranges shift.

Treat lender-specific refi quotes as their own page group with one URL per lender. Refi scenario pages give the typical ranges; lender pages give current quoted rates. Separate groups keep templates focused and editorial scope clear.

Cash-out refi adds a new-loan-balance column and a cash-out amount column. The break-even math gets more nuanced because part of the new payment is debt service on cashed-out funds. Add a structure column to flag the row as cash-out and render structure-specific notes via a selector mapping.

FHA streamline and VA IRRRL have specific eligibility rules (existing program loan, no-cash-out, low-doc). Add an eligibility array column rendered via a list mapping so program-specific requirements render uniformly. The template stays the same; the program block renders the program-specific rules.

SleekRank caches the source per cacheDuration set in seconds. Edit the sheet, clear the SleekRank cache via WP-CLI or admin, and the next request rebuilds the page with new data. For market-sensitive ranges, set cacheDuration to a day so updates land quickly.

Yes. Each generated URL is a real WordPress page included in the sitemap. The base template is excluded automatically so the scaffolding does not compete with real calculator pages. Run a rewrite flush after adding new slugs so the routes resolve immediately on production.

Yes, but that's a comparison hub rather than a per-scenario URL. Build /refinance-calculators/ as a comparison table that pulls from the same sheet and shows rate drop, closing costs, and break-even across scenarios. SleekRank handles the detail pages; the hub uses the same source.
