Compare Stay Options as Nightly Rate Plus Add-Ons — Free
The headline nightly rate is only the first line of the stay. Add the nightly extras each option carries — breakfast, resort fees, parking — multiply by the nights, and compare the totals the ads never print.
The proof surface
Folio audits check a stay’s bill after checkout. This does the comparison before booking: every option’s nightly rate plus its per-night add-ons, scaled across the same stay length, with the priciest options flagged against the cheapest.
Why the flat version breaks
Comparing options across different dates
Rate calendars move faster than the comparison can survive; same dates or no comparison.
Leaving resort and parking fees out of the add-on column
The add-on column is where unbundled fees belong; that is the point of the split.
Treating a prepaid rate as a lower nightly rate
Prepaid totals divide by nights only if the cancellation terms are identical.
How to work the stay total chart
Same city, same nights, same party — the comparison only holds when the dates match.
The nightly room rate in one column; the per-night extras in the second — resort fees, breakfast, parking, service charges that the headline rate excludes.
Three nights applies to every option in this run. Short stays magnify fixed fees; long stays magnify rate differences.
The chart totals each option and flags every total above the cheapest. A sixty-five-a-night hotel with fifteen a night of extras ties an eighty-a-night hotel with none — and a fifty-five-a-night option carrying thirty a night of fees loses on night two.

FIRST-LOAD
Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Stay-cost arithmetic on the rates and fees you supply. Not a booking, price guarantee or travel-insurance determination; confirm the final rate, taxes and fee schedule with the property or booking site before paying, and read the cancellation terms before treating any total as committed.
Data note: Everything runs in this browser tab on the stay total chart: your stay option | nightly rate | add-on cost per night stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.

What this is built on
- Method: Three nights applies to every option in this run. Short stays magnify fixed fees; long stays magnify rate differences.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Before: Rate calendars move faster than the comparison can survive; same dates or no comparison. After: the stay total chart shows the working beside each named row so the reader can change the assumption and inspect the consequence.
Optional AI formatting, not calculation
For this stay total chart, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a stay total chart. Return plain rows only: stay option | nightly rate | add-on cost per night. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: stay option | nightly rate | add-on cost per night. No AI response is executed as code.
