Downshift

Retirement decisions deserve better than noise

Downshift exists because the transition from earning money to living on it is full of one-time decisions — claiming ages, rollovers, conversion windows — and most of what surrounds those decisions online is either a sales funnel or a firehose. We build the quiet middle: free tools that do real math, explain their assumptions, and let you think.

Our planning philosophy

Three beliefs shape everything on this site. First, clarity beats optimization: a plan you understand and follow outperforms a perfect plan you don't. Second, the big rocks matter most — when you retire, when you claim Social Security, how much you spend, and where your accounts sit tax-wise move the needle far more than picking funds. Third, calm is a feature: fear sells products, but it makes bad plans. You'll never see a countdown timer here.

Who's behind Downshift

Placeholder — replace before launch

Founder biography goes here: who you are, the work behind the site, and why this audience. Include real credentials only (licenses, designations, education) with issuing bodies, and disclose the nature of any advisory business relationship. Do not publish this page until this section is completed and reviewed.

Placeholder — professional credentials

List verifiable credentials and registrations here (e.g., designations and the granting organizations, and any firm affiliation or regulatory registrations, if applicable). Remove this block if operating purely as an educational publisher.

How the calculators are built

Every calculator runs on standard, documented financial formulas — amortization, compound growth, bracket-by-bracket tax math, the SSA's published reduction and delayed-credit factors, the IRS Uniform Lifetime Table. The formulas live in tested code, separate from the interface, with automated tests covering the math including edge cases like zero and out-of-range inputs.

Just as important is what we don't do: no black-box scores, no false precision, and no burying the assumptions. Each calculator lists its methodology, its simplifications, and a last-updated date right on the page. Estimates are labeled as estimates.

Where the numbers come from

Tax figures come from IRS revenue procedures for the labeled tax year (2026 figures from Rev. Proc. 2025-32). Social Security rules and wage-base figures come from the Social Security Administration. Medicare premiums and IRMAA tiers come from CMS announcements. Long-term-care costs use the CareScout (Genworth) Cost of Care Survey national medians, labeled by survey year. State income-tax entries are labeled with their data year and marked when simplified.

Editorial standards

Guides and articles are written to an eighth-grade reading level without talking down, checked against primary sources (IRS, SSA, CMS publications), and updated when the underlying rules change. We name uncertainty where it exists, present tradeoffs rather than verdicts, and never publish content whose job is to scare you toward a product.

How often information is reviewed

Annual figures — brackets, contribution limits, wage bases, Medicare premiums — are reviewed each fall and winter when the IRS, SSA, and CMS publish updates, and the affected calculators' last-updated dates change when we do. If you spot something stale or wrong, please tell us; corrections ship fast.
