SoloFig: the freelancer calculator shelf

Field notes

SoloFig groups a wide range of self-employment decisions into individually named calculators rather than presenting one general-purpose finance tool. The catalogue covers both familiar tax questions and less commonly surfaced risks, including a client accounting for 50% of revenue, the hidden annual cost of late payment, and the APR implied by invoice-financing fees. It also links to longer guides intended to explain the arithmetic behind the results.
