Free Calculators & Tools for Seniors (2026)

Five interactive tools built around the questions older adults and family caregivers actually ask: what Medicare costs, what a reverse mortgage pays out, whether the house is safe to age in, whether keto is risky, and what Medicare actually covers. Everything runs in your browser — no name, email, phone, or address required, and your inputs are never sent to a server.

📈

IRMAA Medicare Surcharge Calculator

Find out if your income triggers extra Medicare premiums in 2026. Enter your MAGI to see your exact Part B and Part D surcharge for the year.

When to use: Use this before a Roth conversion, a large RMD, or selling appreciated assets.

 🏠

Home Safety Check

Walk through your home room by room with this 25-question checklist. Get a safety score and a personalized fix-it list to prevent falls.

When to use: Use this before applying for home-modification grants or after a near-miss fall.

 🏡

Reverse Mortgage Calculator

Estimate your HECM principal limit, lump sum, line of credit, and monthly-for-life payment. Same HUD math the lender calculators use, no personal info required.

When to use: Use this before any HUD counseling appointment or lender call.

 💙

Medicare Coverage Checker

Find out if Medicare covers a specific service, what it costs, and tips to save. Searches 40+ services instantly in plain English.

When to use: Use this when a doctor recommends a test or device and you want to know what you'll pay.

 🦴

Keto Safety Quiz

12 questions about your medications and conditions. Find out whether a ketogenic diet is safe, conditional, or off-limits for you specifically.

When to use: Use this before changing how you eat — keto interacts with several common senior medications.

Which Calculator Should I Use?

Match your question to the right tool. None of these replace professional advice — they help you walk into the conversation already knowing the numbers.

  • "Will my retirement income trigger Medicare surcharges?" → IRMAA Medicare Surcharge Calculator. Especially important if you're considering a Roth conversion, taking your first RMD, or selling a long-held asset.
  • "How much money can I get from a reverse mortgage?" → Reverse Mortgage Calculator. Uses the same HUD Principal Limit Factor table as AAG, Mutual of Omaha, LendingTree, and every other HECM lender — without the lead-capture form.
  • "Is my home safe enough to keep aging in place?" → Home Safety Check. Most home-modification grants and Medicaid HCBS waivers ask for a hazard inventory; this gives you one.
  • "Does Medicare cover X?" → Medicare Coverage Checker. Faster than calling 1-800-MEDICARE and clearer than the official handbook.
  • "Is keto safe for me given the medications I take?" → Keto Safety Quiz. Flags the conditions and prescriptions that make keto a bad idea before you start.

How These Tools Differ from Lender and Insurance Calculators

Almost every "free reverse mortgage calculator," "free Medicare calculator," or "home safety assessment" you find online is run by a lender, an insurance broker, or a lead-generation firm. They require your name, phone, email, and sometimes Social Security number before showing you a number, and the result triggers a sales pipeline within minutes. Some of those tools are accurate; some round in the lender's favor; almost all of them sell your contact information.

These five tools are different in three concrete ways:

  • No data collection. Everything runs in JavaScript inside your browser. Nothing you enter is sent to a server, logged, or stored. We can't see your numbers and neither can a third party.
  • No accounts, no sales handoff. No email signup, no marketing follow-up, no lender referral. We don't make money from these tools and we don't sell leads.
  • Transparent math. Each tool explains the formula, the assumptions, and what's not covered. The reverse mortgage calculator shows the HUD PLF table; the IRMAA calculator shows the 2026 brackets verbatim; the home safety check publishes the question logic. If you want to verify our math, you can.

For most decisions you'll still want a professional — a HUD-approved housing counselor, a fee-only financial planner, a licensed Medicare broker, an occupational therapist, a registered dietitian. These calculators help you walk into those conversations already knowing the numbers, which usually saves money and shortens the meeting.

What's Coming Next

The tools above are the first batch. Calculators in active development:

  • Social Security claiming age comparison (62 vs 67 vs 70) with break-even math
  • Medicare Advantage vs Original Medicare + Medigap cost comparison
  • Long-term care insurance premium-to-benefit ratio screen
  • Required Minimum Distribution (RMD) calculator with bracket-impact preview
