Free rental calculators for your website

Three HostCalmly calculators you can put on your own site for free: cleaning fee calculator, break-even rate calculator and linen calculator. Copy one block of code, paste it into your page's HTML and the calculator appears with a credit link under it. No sign-up, no fee.

Cleaning fee calculator

Adds up cleaner pay, laundry, supplies and anything else one turnover costs, then shows the cleaning fee that still covers it after the platform takes its percentage: fee = turnover cost ÷ (1 − fee rate). The math is one tap away under the result.

Good for: A cleaning company's pricing page, a co-host's services page or a host group's resources.

Live preview: the widget exactly as your visitors get it. Try it. Open the full cleaning fee calculator.

Starts 1,680 px tall, then grows or shrinks to fit its result. Fits any column from 360 to 700 px wide.

Break-even rate calculator

Takes a month's fixed costs, booked nights, average stay, turnover and per-night costs, the cleaning fee and the platform fee, and shows the lowest nightly rate that covers them. An optional monthly target shows the rate that earns it, and the breakdown shows the rate at 10 to 26 booked nights.

Good for: A property manager's owner page, a co-host's site or a blog post about pricing.

Starts 1,720 px tall, then grows or shrinks to fit its result. Fits any column from 360 to 700 px wide.

Linen calculator

Counts the sheet sets, bath and hand towels, washcloths, bath mats, mattress protectors and pillows a rental needs from its beds, guests, bathrooms and laundry routine. It starts with 2 Queen beds and 4 guests; visitors change the beds and counts, and nothing they enter is saved.

Good for: A linen service's or cleaning company's site, a rental designer's checklist page or a host group's resources.

Sizes and colors

  • Width: the widget fills its column up to 700 px. It's laid out for 360 to 700 px and still works at 320 px.
  • Height: the short script in the code sets the iframe's height from the widget's hostcalmly:embed-height message, so there's no inner scroll bar. Where a site builder strips scripts, the iframe keeps its starting height and scrolls inside.
  • Several on one page: paste each code block where that widget goes. Each script sizes only the iframe that sent the message, and only accepts messages from hostcalmly.com.
  • Colors: the widget follows each visitor's light or dark setting. To match your site, add ?theme=light or ?theme=dark to the iframe address.

Privacy inside the widget

The widget sets no cookies and runs no analytics or tracking. What your visitors type stays in that browser tab and is gone when they close it: nothing is saved in their browser or sent to us. The only thing the widget tells your page is its height. Loading it is an ordinary request to HostCalmly, so our host keeps the basic server log any website gets (IP address, browser type, page and time).

Terms of use
