Monthly Income Booster (Web)

About Monthly Income Booster (Web)

The web version of Monthly Income Booster is a free set of calculators and guides for working out what extra income is actually worth before you spend a weekend on it. Type a monthly income target and the planner works backwards from it, or go straight to the tool you need: 76 calculators for platform fees, self-employment tax, gig pay, rental cash flow, creator revenue and service pricing; worked pay conversions (hourly to yearly, yearly to hourly, monthly to hourly); and 30 income-type pages that explain how each route earns, what it pays at each stage and what usually goes wrong. Every calculator states its assumptions: pay conversions use the standard 2,080-hour working year, and tax figures use the 2026 federal brackets and Social Security wage base. Nothing is behind a sign-in, and no calculator asks for an email before showing its answer.
