Examples/New baby + bigger home
Two Scenario events

What if a new baby means we also outgrow our home?

A new baby can change recurring costs, leave, childcare and income. It can also trigger another decision: whether the current home still works. Styrvia lets you place both events on one timeline instead of modelling them as unrelated choices.

New baby + bigger home: illustrative result

This scenario shows why two Scenario events should be modelled together. Child/dependant costs may begin before a larger-home purchase, so the model can show the combined pressure on accessible money, mortgage capacity and long-term wealth rather than treating each decision in isolation.

What to look at in Styrvia

This example is about interaction. Two individually manageable events can create a much tighter period when they happen close together, so the timeline and liquidity matter as much as ending wealth.

Questions to explore
Can we afford a bigger home after having a child?

Model the new family costs first and the home change at its planned date. Styrvia then shows whether the combined cash-flow and housing commitments leave enough accessible money rather than testing the two decisions in isolation.

What happens when family costs start before the home purchase?

When family costs start before the purchase, they reduce the cash available to build or preserve the deposit and can lower the reserve available for moving costs. The timeline makes that overlap visible before the larger housing commitment begins.

How much accessible money remains after both events?

The accessible-money path captures the deposit, transaction costs, new debt payments and family expenses together. Comparing the lowest point with the starting reserve shows how much liquidity remains after both events are included.
