About QuickFinance Tools
Free, accurate personal finance calculators for independent earners in the US, UK, and Canada.
What This Site Is
QuickFinance Tools is a collection of free personal finance calculators built for people whose financial situations do not fit the standard mold. Every tool was designed to answer a specific, practical question that freelancers, gig workers, and independent contractors actually ask — not the generic questions that have been covered a thousand times by big financial sites.
Who These Tools Are For
Most personal finance tools were designed for salaried employees — W-2 workers in the US, PAYE workers in the UK, T4 employees in Canada — with stable paychecks and employer-managed tax withholding. These tools handle mortgages and 401k contributions well. They handle variable income, self-employment tax, and gig-economy-specific calculations poorly, or not at all.
QuickFinance Tools fills that gap. The calculators here were built for:
- US freelancers and 1099 contractors estimating self-employment tax and quarterly payments
- UK self-employed workers and sole traders planning their finances outside PAYE
- Canadian self-employed individuals navigating CPP contributions and T2125 filing
- Gig workers, side hustlers, and anyone with variable or mixed income
- Salaried employees in any country who want clearer answers about debt, savings, and investing
The Calculators
Methodology and Accuracy
All calculations are implemented based on publicly available tax rates, IRS publications, and standard personal finance formulas. US tax figures are based on 2026 federal tax brackets and the 2026 standard deduction. Self-employment tax calculations follow IRS Schedule SE methodology.
For UK and Canadian users, the FAQ sections on each calculator explain the equivalent local rules and confirm which calculations are currency-neutral versus US-specific.
Compound interest, debt payoff, emergency fund, and savings goal calculations use standard financial mathematics that applies universally regardless of currency or country.
