As answered by people managing SQL Chat and VerifiedLimits.
VerifiedLimits's answer:
Most calculator sites treat HSA and 401(k) limits as one generic feature buried in a catalog of unrelated tools. Ledger&Leaf does the opposite: twelve calculators, one category โ US tax-advantaged account thresholds โ each verified directly against IRS Revenue Procedures and Notices, not estimated.
It also covers what generic calculators skip entirely:
No login, no account, no data stored โ every number is calculated in your browser and nowhere else.
VerifiedLimits's answer:
Getting a contribution limit wrong costs real money โ a 6% excise tax on excess HSA or IRA contributions, a missed employer match, a blown catch-up window.
VerifiedLimits's answer:
US taxpayers actively managing an HSA, IRA, or 401(k) who want a precise answer, not a rough estimate โ DIY investors from communities like Bogleheads and r/financialindependence, and people navigating a specific edge case: a job change mid-year, a shift in HDHP coverage, or catch-up eligibility that simpler calculators don't model.
VerifiedLimits's answer:
Ledger&Leaf started from a simple observation: the numbers that actually decide whether an HSA or 401(k) contribution is safe โ prorated limits, catch-up thresholds, mid-year coverage changes โ are scattered across dense IRS documents that most calculators simplify past the point of being reliable.
It's built and maintained by a solo founder, one calculator at a time, verifying every figure against the primary source before it ships. The goal isn't to be another all-purpose finance hub โ it's to be the place people go when this specific answer needs to be right.
VerifiedLimits's answer:
A client-side single-page application, entirely browser-based:
No backend, no database โ every calculation runs client-side, which is also why no login or account is ever required.
