UK Irregular Income & Buffer Planner | Variable Income Budget Excel Spreadsheet

Your income may change every month. Your money plan doesn't have to.

The MoneySavvyUK Irregular Income & Buffer Planner is an Excel workbook designed for people whose income doesn't arrive as one predictable monthly salary.

Whether you're freelancing, self-employed, working variable hours, earning commission or building side-income, the planner helps you organise changing income without trying to force it into a conventional fixed-salary budget.

Use it to:

✓ Calculate your monthly essential-cost baseline

✓ Track multiple income streams

✓ Compare expected and actual monthly income

✓ Plan for annual and irregular expenses

✓ Compare lean, normal and strong income months

✓ Build and track your own chosen buffer target

✓ See how many months of entered essential costs your current buffer represents

✓ Review your previous 12 months of income

✓ Test “What if next month's income is lower?” scenarios

✓ See your key figures together on one simple dashboard
