Medical Savings Calculator
Calculate the timeline to build a dedicated medical emergency reserve fund, factoring in your target deductible/OOPM goal, monthly contributions, and high-yield savings interest.
Budgeting Summary
Medical Reserve Timeline Formula
Months to Goal = log[(Goal × r / Monthly Contribution) + 1] / log(1 + r)- Reserve Goal: Target amount equal to your plan’s annual Out-of-Pocket Maximum.
- High-Yield Savings Rate: Interest compounding monthly to accelerate goal completion.
- Funding Milestone: Percentage progress toward medical security.
Step-by-Step Worked Example
Calculation Steps:
- Remaining Goal to Fund = $6,000 - $1,500 = $4,500.
- At $250/month with 4.5% compound interest, the goal is reached in 17 months.
- Total Principal Contributed = $1,500 initial + ($250 × 17) = $5,750.
- Interest Earned = ~$250.

Frequently Asked Questions
How much should I keep in a medical emergency fund?
You should ideally hold enough cash to cover your health insurance plan’s maximum out-of-pocket limit (typically $3,000–$9,000 for individuals, $6,000–$18,000 for families).
Should I keep medical emergency savings in a regular bank account or HSA?
If eligible for an HSA, contributing there provides immediate tax deductions. If enrolled in a non-HDHP plan, a dedicated high-yield savings account (HYSA) is the best alternative.
