NB. I've purged most of the earlier posts (below)
Martin Kreuzer's original question was how to handle intermediate results!
Anyway, staying off topic for now, Ric's tongue-in-cheek proposal is
"explicit",
but perhaps you wanted something more so, Linda.
He's got a point, though - would you like it reexpressed in COBOL?
Meanwhile, this _might_ be along the lines you're thinking of:
NB. Ric's tacit verb
pmt=: {: * 1&{ (([: (% <:) (^~ >:)) * ]) 1200 %~ {.
NB. attempt to render it explicit... (explicate it?)
pmte =: 3 : 0
'r t b' =. y % 1200 1 1
NB. OR: b =. {:y [ t =. 1{y [ r =: 1200%~ {:y NB.!!!
NB. (^~ >:) ===>
incrtot =. t^~1 + r
NB. OR: =. (1 + r)^t
NB. ([: (% <:) (^~ >:)) ===> incrtot % incrtot - 1
NB. (([: (% <:) (^~ >:)) * ]) ===> (incrtot % incrtot - 1) * r
NB. whole thing ===>
b * (incrtot % incrtot - 1) * r
)
BTW, the fragment, incrtot % incrtot - 1, suggests a further refinement -
or is it? - dealing with an intermediate result, anyway!
incrtot % incrtot - 1
1 % 1 - 1 % incrtot
% 1 - % incrtot
-.&.% incrtot NB. too tacit?
NB. Also, my antiallergenic tacit version avoiding @ and @:
pmtmd =: [: (*`(] * [: (% <:) (^~ >:))/) 1 1 1200 %~ |.
'r t b'=. 5.75 240 12500
(pmt, pmte, pmtmd) r,t,b
87.7604 87.7604 87.7604
FWIW!

Linda,
You may want to define exactly what you mean by "explicitly" and what
you're trying to show/achieve.
Here is a tongue-in-cheek potential solution to your request:
pmt=: 13 : '({: * 1&{ (([: (% <:) (^~ >:)) * ]) 1200 %~ {.) y'

Now can someone, not Ric, write his version explicitly.

Without @, but IMO this is a case where @ definitely improves readability!
pmt=: {: * 1&{ (([: (% <:) (^~ >:)) * ]) 1200 %~ {.
