Frequently Asked Questions
How do I budget when my income varies every month?
Calculate your baseline income (average of your 3 lowest-earning months), budget based on this amount, and save excess from high-income months to cover low-income months. Use the 'pay yourself a salary' method by depositing all income into a smoothing account and transferring a fixed amount to your current account each month.
How much should I save for tax as a freelancer?
Set aside 25-30% of your gross income for tax and National Insurance. Open a separate tax savings account and transfer this percentage immediately when you receive payment. If you earn over £50,270, increase this to 42%. Never spend money earmarked for tax.
How big should my emergency fund be with irregular income?
Aim for 6-12 months of expenses, significantly more than the 3-6 months recommended for salaried workers. With irregular income, you need a larger buffer to smooth out cash flow and cover extended periods of low income. Start with 3 months and build up gradually.
Can I get a mortgage with irregular income?
Yes, but it's more challenging. Lenders typically want 2+ years of accounts showing consistent income. Use a specialist self-employed mortgage broker who knows which lenders are most flexible. You may need a larger deposit (15-20%) and will be assessed on your average income over 2-3 years.
How do I handle months when I earn nothing?
This is why building a large buffer is crucial. In zero-income months, draw from your income smoothing account to pay yourself your baseline 'salary.' If your buffer runs low, prioritize essential expenses (housing, utilities, food) and contact creditors to arrange payment holidays if needed.
