Found this really handy takeoff and landing calculator through a reddit post. It's from Captain Tux on the X Plane website. It's a bit weird to get up and running, but it is very handy, and there are a ton of planes you can use it with as well as create your own profile for different planes.
 

Here's the link to the X-Plane Page

and

Here's the link to the Google Drive containing the download

It's basically a BAT file that you can use to either open a window in your browser, or use a QR code to open on your phone or tablet.
These are the settings I use for the PMDG 737.

MTOW 70307kg / 155000lbs

MLW 58604kg / 129200lbs

MZFW 55202kg / 121700lbs

BEW 38510kg / 84900lbs

Max. Fuel 20891kg / 46057lbs

You'll click on "Editors" in the toolbox to create a new profile for the plane you're using.

In the upper right hand side, there's a little gear box where you can change your units from Meters/Feet, lbs/KG, and select your weather source from NOAA/VATSIM/IVAO.

When you do your calculation, simply putting in your departure airport and runway will populate the winds, temp and QNH/Altimeter. You'll have to decide (just as in real life) if you're using anti-ice, engine bleeds, and whether the runway is wet, dry, etc.

 

Props to Captain Tux!

are there any calculators that have the CFM56-7B27 out there?

i looked in topcat and this app and also TOPER i'm not finding a calculator to use for the BBJ

the calcs for the regular 700 sorta work but the B27 has a lot more thrust and also it gets capped at about 20k less MTOW than the bbj supports
