I am looking for a shareware source code for a mortgage calculator to place on a WordPress website?
Greatly appreciate your help.
shareware isn't free...
And you won't find a mortgage calculator that's useful for websites unless they're highly localised websites as mortgage rules and laws make the outcome very different across countries or even smaller areas.
And of course different suppliers have different variations, leading to different results again.
Which is why every mortgage supplier writes its own software.
