Side-by-Side Comparisons
Some financial decisions are not a single calculation but a choice between two paths. These tools run both scenarios in parallel on the same inputs and show you the gap at the end, rather than leaving you to compare two separate results by hand.
Why comparisons beat single calculators
A calculator answers “what does this produce?”. A comparison answers “which of these should I choose?” — and that second question is usually the one you actually have. Running two options separately makes it easy to compare them on the wrong basis: pre-tax against post-tax, or a figure that includes opportunity cost against one that quietly does not.
Each comparison here applies the same inputs, the same time horizon and the same tax treatment to both sides, so the difference you see is the real difference rather than an artefact of inconsistent assumptions.
