For the beginners out there, a short how to of this calculator:
1) Select Chapter, Click load
2) Add other items you can get in quantity.  I'd suggest adding those in greatest supply first.  (You might also consider removing the most expensive items...)
Obsolete step: 3) Click 'Calculate!'
4) Restrict to rank as appropriate (choices are min/max values) -- Limits displayed results to those ranks.
5) Select an item from the results.
6) Fuse it.

If the results don't make any sense or if the calculator seems broken, try the Reset button.
If you have problems with copying the details, this can be corrected by upgrading to Java 1.5.

This is not intended to be the be-all/end-all of information for Stella Deus, nor even for Fusion.  It is still advisable for you to check out the FAQs/Guides for Stella Deus, many of which can be found on GameFaqs.  Some of them contain tips for earning the money you need to make many fusions (see: Rich Wallet Trick and Money Glitch).

News:

All fusions from Chapter 1 up to Rank 14 items are very efficient, although problems are still suspected in Chapter 5 with fusing the Rank 15/Rank 16 fusions (results not ideal).

New as of April 9th, 2006:
It's been a while, but I have updates!
Added 'Allowed Waste' Combo Box.  Set to 'Minimal' may add steps, but it will try to make items as efficiently as possible.  Contrast 'Wasteful' which will happily try to fuse R1 items using R16 items (granted, the database doesn't currently officialy support this...)  Wasteful has been seen to exibit difficult hangs (I don't think the reset button would clear these), use with care.  It is designed for use only in the deepest part of the Catacombs (actual value to be seen).
Kudos to Marc who pointed out some inconsistancies in the database (The database can be found in the source files, link below).  The Ceramic Dagger (R1) is no more.
New as of November 11th, 2005:
Added Reset button, for use if the fusion calculator gives you trouble.  Essentially, it clears the results and builds them from scratch (May sometimes provide different, but equivalent results).
I added the button after I ran into some unexplained bug using the calculator from my browser (Chapter Load button not working, results not consistent with available items).  I've tested this button with the bug and it promptly clears the condition.  To see the button at work add the Vampire Cape and Atlantian bow (that order), then look up the Warrior's Cloth (R14) and press the Reset button.
Added: Chapter 13 fusions, mostly the R13+R11=R13 results.  This will make working from the levels in the Catacombs floors that produce R11 items more efficient.
I am planning to add an option to select what types of fusions the calculator favors (From Shop, No Favorites, From Catacombs)
From Shop: Favor easy steps (Fusing items with themselves), Repeated steps (Same step performed more than once) and fewest ingredients (Favor using three of one item over three different items)  This is the current style used by the calculator.
No favorites: Favor Easy steps only.  No other preferences.
From Catacombs: Avoid easy steps.  Favor most ingredients (favor three different items over three of one item).  No other preference.
I want the last option because coming up with those 26 Bloody Lance (R10) I still need to fuse a Virgin Tear isn't exactly easy, while I have 5-10 of most every other R10 item.

New as of November 3rd, 2005:
Fix to both bugs mentioned in the October 29th notes.  These fixes have corrected tallies for some of the fusions in the R16 chart, from Chapter 1 to Chapter 3.
Removal of the Calculate button -- Fusions are re-calculated with every addition/removal.  I hope the calculator is now fast enough the change won't bother anyone.  Yes, the progress bar goes backwards some of the time.  This is normal and expected.  It's not that the calculator is having to back up, it's just finding more work to do.
Minor adjustment to the GUI behavior.  Those of you fusing from the catacombs will benefit from it most...
At this moment, there are no known bugs, but some optimization still remains to be done (yes, faster still!).

New as of October 29th, 2005:
Removed unnecessary elements from the applet: Reduced size by 25 kb.
Memory use reduced: To identify if deep/complex fusions have been changed, instead of remembering all steps in a string, a checksum is used instead.
Result: Bokutoh only fusions work again.  Very fast.  (Much faster than Smirk's engine at this task!)
Simplified: Complexity management.
Pending: Further work to simplify some of the key code so I can fix the remaining bugs without adding more bugs.
Bugs known to exist in the new calculator: Incorrect step count (patch in place), hang condition (patch in place, may be related to the step count bug)

New as of October 19th, 2005:
Replaced: The engine that calculates the actual results.  This was needed due to a minor flaw with the design of the calculator.  While it worked well when everything it used started with the same rank, it had problems working with a poor variety of ranks (i.e. Chapter 1 shops -- only 2 R3 items) or when fusing over many ranks (i.e. R16 items from Chapter 4 shops)  One specific example would be the Virgin Tear which Smirks calculator wants to make for 1023 fusions (can be made for only 677 fusions) from Chapter 4and Hero's Emblem (R5) from Chapter 1, which Smirk's calculator makes for 7 fusions, and mine makes for 5.
The new calculator is slower, but I think it will be fast enough for everyone.  Give a yell if it needs to be faster.  Also, if you don't give it enough starter items, it may run out of memory making the results.  This is a known problem, give a yell if it somehow poses a problem. (Both solutions would require making the program larger).

New as of October 11th, 2005:
Added: A few changes to the user interface, the more obvious ones are the requested increased size of the Results panes.  The separator between them can also be slid side-to-side.
Notes: The separator between the directions and tree can be slid.  For adding seed items, you can now type the first few letters of the item, and then up/down arrow to the correct item.
Please report any problems.  It uses several features I've not yet tested on older versions of Java.  I try not to break things, but there are some things I cannot readily test..
Also: Minor adjustment to choosing between equal fusions.  Result: More repeated steps in making items,  fewer total steps.


General Information:

This Java version has been created by Torrenal and was at one time largly based on the original Smirk's Fusion Calculator which is a .NET implementation.
The story is information provided by AIex and Gundam4fun were the source of much of the original fusion information in the database used by Smirk's calculator.  Kudos for the volume of information they and any other contributors who were able to provide the information that make this such a good program.  (Would Smirk please step forward and announce credits?)
The only parts retained from Smirk's version relate to the user interface and some file I/O.  While Smirk's calculator uses an efficient method to quickly calculate the fusions, there was a flaw where it would not revise existing fusions as better ones became available.  Note that the database.txt file used by the Java version is an abridged version that at the time of this writing will not work properly in Smirk's original Calculator.

This version is written in Java 1.3.  If you need to upgrade, visit java.sun.com
A known bug in Java 1.4 prevents copying from the details pane of the applet, upgrading to Java 1.5 will fix this.
The Java Source and supporting files can be found here.

Ideal: Equal to the number of ranks separating highest available item from the target item.  Raise two to that power and subtract one.
While some items may be made using the ideal number of fusions, others will always require some extra steps
