Reading the result
Financial projections compound small assumption changes into large differences over time. Rates, fees and tax treatment vary by lender and jurisdiction, so treat the output as a well-structured estimate for comparing options rather than a quotation.
Figures that change annually — tax bands, contribution limits, statutory rates — are exposed as editable inputs. Check them against current published values before relying on the result.
