How to use scenarios when one or both incomes fluctuate during the year.
Use this as a planning guide for 2026. Your final outcome depends on your circumstances.
When income fluctuates, a single annual number can hide the range of outcomes. Scenario testing (low/typical/high) helps you see whether the same option stays best across the range.
Run the simulator three times: conservative income, typical income, and optimistic income. If the ranking stays the same across all three, you can treat the result as more robust for planning.
When the gap between options is small, the decision is more sensitive to credits and thresholds. That is a good time to review related topics like pension contributions and extra income types.
These topics are often searched together with Variable income: how to compare joint vs separate.
