Eight kinds of cost. All of them add up.

Your Magic Number

Not what the office costs. What it costs after tax.

A $12,285 hole in your budget needs more than a $12,285 raise to fill it, because raises get taxed. RTO Calculator does the gross-to-net math so the number you bring to the table is the real one.

Then it breaks it down to the day: each office day costs you $47.25 more than working from home.

Every line, itemized

See exactly where the money goes.

Commute, meals, time, home office, wardrobe, each with its share of the total. The $4 office coffee turns out to be a $1,040 line item.

It counts savings too: lunch at home isn’t free, so the breakdown nets it out honestly.

Before your 1:1 with HR

What exactly is the Magic Number?

The minimum gross (pre-tax) raise that would make returning to the office financially neutral for you: your total net RTO cost, grossed up for taxes so the raise actually covers it after withholding.

Is it really free?

Yes. The full calculator, all eight categories, and your Magic Number are free with nothing locked. Pro ($4.99 once) adds the tools for acting on it: raise comparison, PDF export, scenarios, widgets, Siri, and the Negotiation Guide.

Do I need an account? Where is my data stored?

No account. Everything you enter stays on your device. There are no ads and no tracking.

What if I’m hybrid, not full-time in office?

Set your office days per week and everything scales. With Pro you can save scenarios side by side, like 3 days vs. 5, or driving vs. transit, and compare the difference.

Is this financial advice?

No. It’s an estimate built from the numbers you enter plus national-average defaults. It gives you a well-organized starting point for a conversation, not a guarantee.

Know your number before HR does.

Two minutes, eight categories, one number worth bringing to the meeting.
