What the irregular income floor controls
The calculator averages three selected lower-income months, removes the entered tax set-aside and compares the remainder with essential household costs. It also sizes an income reserve from the chosen number of months.
- Use completed low months, not hoped-for future invoices.
- The tax set-aside is a planning input and not tax advice.
- Keep business operating cash separate from household cash.
A floor separates survival from strong-month choices
The base transfer should work without depending on invoices that have not been paid.

Choose evidence from ordinary difficult months
Use completed months that represent normal downside, not a disaster month that is unlikely to repeat and not the best quarter of the year. Bank deposits, invoices paid and business records provide better evidence than memory.
If work is seasonal, select low months from the same season across different years. A simple three-month average is a planning floor, not a forecast of every future deposit.
Separate tax and business cash first
Self-employed or commission income can include money that is not available for household spending. Remove a tax set-aside and keep business operating needs in a separate plan before setting the household transfer.
The percentage in this tool is user supplied. Confirm actual filing and payment obligations through current official guidance or a qualified professional rather than treating the result as tax advice.
Use strong months to stabilize the system
When income exceeds the floor, refill the income reserve first, then fund annual costs and priority goals. This prevents a strong month from permanently increasing recurring lifestyle costs.
If the after-set-aside floor does not cover essentials, the base plan is structurally exposed. Reduce fixed commitments, increase reliable income or build a larger reserve before promising money to flexible goals.

Common questions about this calculator
Why use three lower-income months?
They provide a simple downside reference from actual experience. Seasonal workers should choose comparable low-season months and review the floor when the business changes.
Is the tax set-aside calculated by the site?
No. You enter the percentage. Confirm actual obligations through current official information or a qualified professional before moving or spending tax money.
