The calculator your Odoo
has been missing.
A floating, draggable calculator that follows you across every Odoo screen. Standard math, scientific functions, and a unique Money Mode that adds numbers in different currencies in a single expression.
Switch the keypad to match the task — not the other way around.
One click flips the calculator between Standard, Scientific and Money. The display, keys and history all adapt automatically.
Fast, clean arithmetic.
Add, subtract, multiply, divide, percent. A pinned expression preview keeps the formula visible while you type.
For when a deal needs trig.
sin, cos, tan, √, π and exponents — with a toggle between degrees and radians so the keypad never lies to you.

MONEY MODE
|
Add different currencies in the same expression.
Type 100 USD + 50 EUR + 2000 JPY, pick the currency you want the answer in, press =. The widget reads Odoo's native rates to return a single number.
Six small details that make it feel native to Odoo.

✥
Draggable everywhere
Grab the header and drop the popup anywhere on the viewport. It stays out of the way of the record you're actually editing. |
↺
Persistent state
Remembers whether it was open, minimised or closed, and where you left it — even after a page reload or navigation. |
☷
History with notes
Every calculation is saved. Add a one-line note — "Quote 4231" — and click any row to reload the expression later. |

Theme adaptation
Reads Odoo's CSS variables on mount and matches the active backend theme — looks right on light and dark backgrounds. |

Money Mode, step by step.
Instead of converting first then adding, Money Mode lets you type the expression exactly as it appears on your invoice — with each number tagged to its own currency.
Pick the input tag
Use the left dropdown to tag the number you're about to type (e.g. USD).
Type & operate
Type 100, then +. The display shows 100 USD + — tag attached automatically.
Switch, type, repeat
Change the tag to EUR, type 50. Keep chaining as many currencies as you want.
Set result & =
Pick the result currency on the right (e.g. INR) and press =. Done.
Built for Odoo 17, 18 & 19. Zero configuration.
Install the module, refresh your browser, and the floating calculator icon is there. No setup wizard, no external services.

No. Every history row is owned by its creator and a record rule blocks every other user. The shipped test suite verifies this. |
By design — the calculator is meant for in-the-moment math. A scheduled cron sweeps rows older than an hour. Disable it from Settings → Technical → Scheduled Actions if you need it permanent. |

No measurable impact. Mounted once globally, uses native OWL 2 components, only fetches data when you open it. |
