FAQ: How Do I Add a One-Off Expenses To My Plan
For some more regular large expenses (vehicle purchase, home maintenance, regular travel) we recommend setting aside a monthly amount in a "sinking fund". This can be captured in the Discovery > Expenses fields.
For one-time costs you can add year-by-year changes in Planning > Projections > Table. You will open up the "Other" expenses column and add an override for a lump-sum expense in the year you expect additional spending. Then recalculate the plan to integrate that change.
This functionality could also be used to add other one-time expenses like a large home reno, a larger one-time vehicle upgrade, a recreational vehicle purchase etc. etc.
You can see an example in the above video for 'Gifts to Children'.
