How it works
A dental and vision spend planner answers the question insurance marketing obscures: what does mouth-and-eyes maintenance actually cost, and can a savings habit replace the premium? The method treats dentistry as two distinct cash-flow problems. Routine care — cleanings with exams and imaging, plus averaged vision spending — arrives predictably and belongs in the monthly budget as-is. Lumpy care — the crown, the root canal, the implant — arrives unpredictably but not randomly: most adults need something major every three to eight years, which makes it a textbook sinking-fund problem rather than an emergency. Dividing the major-work cost by its recurrence interval and adding routine spending produces the expected annual figure; a simulator then schedules actual events across ten years, deposits the set-aside monthly into a yield-bearing fund, and solves for the smallest deposit that never lets the balance turn negative. The output reframes the insurance decision itself: against dental insurance's typical one-to-two-thousand-dollar annual maximums, self-funding expected spending plus a buffer often prices competitively — especially where main usage is preventive care. Honest caveats cut both ways. Genetic luck can stack two root canals into one year, which is precisely what risk pooling is for; and dental inflation runs hotter than CPI, so revisit costs and recurrence with your own treatment history as the guide.Formula
expected annual = cleanings x cost + major work / recurrence years + vision | deposit = smallest level amount keeping the simulated fund positive
Tips
- Book heavy work early in the year your fund is fullest — timing beats willpower.
- Ask for the self-pay fee schedule; many practices discount 10–20% below insured rates.
- Phase major treatment — a crowned tooth can wait a quarter; an infected one cannot.
- Hold the fund in a separate labeled high-yield account; unlabeled buffers get spent by December.
- Recalibrate after each major episode — your personal recurrence interval beats any average.
