Estimate the cost and coverage value of short-term health insurance plans compared to ACA marketplace plans for gap coverage.
Short-term health insurance (STHI) provides temporary coverage for gaps between major medical plans. These plans are significantly cheaper than ACA-compliant coverage ($100–$200/month vs $400–$800+) but come with substantial limitations: pre-existing condition exclusions, benefit caps, and limited coverage.
STHI is designed as a bridge, not a long-term solution. Plans typically last 3–12 months and may be renewable for up to 36 months in some states. They're popular among people between jobs, aging off parents' plans, or waiting for employer coverage to start.
This calculator compares the cost and effective coverage of a short-term plan versus an ACA marketplace plan. These are educational estimates only and not actual insurance quotes.

By automating the calculation, you save time and reduce the risk of costly errors in your planning and decision-making process. This tool handles all the complex arithmetic so you can focus on interpreting results and making informed decisions based on accurate data.
Short-term plans are tempting because of low premiums, but their coverage gaps create hidden financial risk. This calculator quantifies what you're actually getting for your premium dollar versus a comprehensive ACA plan. Having a precise figure at your fingertips empowers better planning and more confident decisions. Manual calculations are error-prone and time-consuming; this tool delivers verified results in seconds so you can focus on strategy.
STHI Total Premium = Monthly Premium × Months STHI Worst Case = Total Premium + Deductible (capped at benefit limit) ACA Total = (ACA Premium − Tax Credit) × Months ACA Worst Case = ACA Total + Out-of-Pocket Maximum Exposure Difference = STHI max exposure vs ACA max exposure
Result: STHI: $600 premium | ACA: $1,200 premium | STHI saves $600 but has coverage limits
Short-term: $150 × 4 = $600 premium, but $5,000 deductible and pre-existing exclusions. ACA: ($600 − $300) × 4 = $1,200 premium, but $8,700 OOP max covers everything. STHI is $600 cheaper in premium but risky if you need care.
The ideal short-term plan candidate is a healthy person needing 1–3 months of catastrophic coverage between jobs or other qualifying events. In this narrow scenario, the low premium provides peace of mind against major unexpected events without the cost of a full ACA plan.
Short-term plans' exclusions create hidden costs. A seemingly cheap $150/month plan can leave you with tens of thousands in uncovered bills if a pre-existing condition flares up or you need maternity care. The total cost of ownership (premium + uncovered expenses) often exceeds an ACA plan's cost.
Before choosing STHI, always check: (1) ACA marketplace with subsidies — you may qualify for near-free coverage, (2) Medicaid eligibility — especially if income is low during the gap, (3) COBRA — expensive but comprehensive, (4) healthcare sharing ministries as another alternative. Short-term should be the last resort, not the first choice.
STHI covers unexpected accidents and new illnesses (like broken bones, appendicitis, or infections). Most plans cover doctor visits, hospital stays, surgery, ER visits, and labs. They do NOT cover pre-existing conditions, maternity, mental health, prescription drugs (usually), or preventive care.
The main risks are: (1) pre-existing condition exclusions mean any prior health issue isn't covered, (2) benefit caps ($250,000–$1M) leave you exposed for catastrophic events, (3) no coverage for maternity, mental health, or prescriptions, (4) insurers can rescind coverage if they find undisclosed conditions. These gaps can leave you responsible for tens of thousands of dollars in unexpected medical bills. Always read the plan's exclusions and limitations carefully before purchasing.
Federal rules allow plans up to 364 days, renewable for up to 36 months total. However, some states limit duration to 3–6 months with no renewal. Check your state's regulations. Renewal doesn't guarantee the same rates — conditions developed during the plan may be excluded upon renewal.
STHI may be suitable if: you're healthy with no pre-existing conditions, you need coverage for a specific short gap (1–3 months), you don't qualify for ACA subsidies, and you understand the coverage limitations. It's NOT suitable for ongoing medical needs or anyone with pre-existing conditions.
Yes, STHI has no enrollment periods — you can buy it anytime. This is one reason people turn to it after missing ACA open enrollment. However, check if you qualify for a Special Enrollment Period first (job loss, marriage, moving, etc.), as an ACA plan would be better.
Most STHI plans have very limited or no prescription coverage. Some offer a small discount card. If you take regular medications, the out-of-pocket drug costs can easily exceed the premium savings compared to an ACA plan that includes prescription coverage.
