Start with shared spending, then separate income
Many household costs are shared, but pension income, State Pension forecasts and tax positions are individual. A couple plan should combine shared spending with separate income timelines.
Different ages can create a staged retirement
One partner may stop work earlier while the other keeps earning. One State Pension may start years before the other. These stages can make the plan stronger or weaker depending on spending and accessible assets.
Tax positions are separate
Pension and employment income are usually taxed by individual, not by household. This means the same household income can produce different after-tax results depending on which partner receives it.
Current modelling limitation
RetirementInSight can model two people, separate pension ages, incomes and State Pension starts. It does not yet model survivor outcomes, such as one partner dying first, changed spending needs or inherited pension rules. Treat couple results as a household projection, not a full estate or survivor plan.
