Three plans people have built, and the question each one started with.
Retirement
When can I retire, and what has to happen before and after?
The date work can realistically stop, and what has to be in place before that date and after it. One of these plans runs twenty years past the last pay cheque, with every cost ageing at its own rate.
Separation
After a separation, can I afford it?
Managing on one income, a version where child support isn't paid, and refinancing the house, each tried with her own numbers. It let her focus on the money side, with somewhere to start, and one less fear.
Sabbatical
How long can I step away, and what does going back look like?
A sabbatical for a mental break. She entered what she had in the bank and what her costs were, and saw how long that would last. Then she tried part-time work, different restart dates and a group of lower costs, all with her own numbers. The sabbatical went the way the plan showed.
Detailed enough to be real, quick enough to play with. Change the year, the house or the car, and watch the line move.
It doesn't tell anyone what to do. It works out the numbers that are hard to work out by hand, especially years from now.
