How EarnPrism approaches calculators
Each calculator is designed to answer one planning question clearly rather than imitate a full professional system. Inputs are kept simple enough to be usable on a phone, and the page explains what the estimate includes and what it leaves out.
How assumptions are chosen
Assumptions are based on broad planning logic: monthly cash flow matters more than annual headlines for budgeting, freelance pricing must account for non-billable time, and debt payoff timelines should make interest visible instead of hiding it. When a page requires a tax, rate, or growth assumption, the user controls the assumption directly.
How pages are updated
Important pages are reviewed for clarity, broken links, internal linking quality, whether the assumptions still match the user problem the page is meant to solve, and whether the related links still move the user toward a useful next step. Update stamps are added to support transparency.
What the calculators do not promise
They do not promise exact payroll, tax, lender, or investment outcomes. They are planning estimates meant to help with comparisons, rough timelines, and next-step decisions.
