About Sumplify

Sumplify helps people understand everyday costs and tax rules with clear facts and free calculators. Every figure on the site comes from an official public source, is dated, and links back to that source.

What we publish

• Calculators for take-home pay, tax, energy bills, solar and commuting costs, using the official rules in effect.
• Data pages for each state or region, updated when the source data changes.
• Change reports when governments or regulators change rates, rebates or rules, labelled as announced, legislated or in effect.

What we don’t publish

We don’t give opinions, forecasts or recommendations, rank products as “best”, or tell you what to buy or invest in. See our Editorial Policy.
