you can create a cash flow table in excel
probably want columns for your, DH and DD ages, then columns for either each retirement or brokerage account or the total from all accounts, a column for new annual savings, columns for annual spending, and social security income at what every ages you plan to take it, columns for side gigs, you may want a separate column for healthcare spending any any other items you want to track separately
start with this year then for next year do the math in the columns to add or subtract savings and spending as required, be sure to account for your stash growth also maybe 5-6%
for example these could be columns assuming 6% interest
Age starting portfolio value retirement savings retirement spending other spending goals, other income goals health care spending cash flow
50 $500,000 $50,000 $0 $0 $6,000 -$10,000 $46,000
51 $576,000 $20,500 -$24000 -$5,000 $6,000 -$11,000 -$13,500
52 $597,060
hopefully this makes sense
in my planning we use about $17k per year for health spending pre age 65 and about $7500 after, although we are not caring for a dependent
I bet if you google retirement cash flow table you may get some other examples or a template
