For banks, insurers & financial services firms
Planning tools on your site
this quarter
Worthune puts planning calculators on a bank, credit union, or insurer website with one script tag and no engineering project. The same platform grows into unified household management: client portals under your own brand. Each calculation follows published rules a compliance reviewer can read, uses government figures with their primary sources, and returns a record of the answer.
Your customers ask the same questions everywhere: can we afford the house, when should we claim Social Security, is refinancing worth it. Answering them on your own website keeps that conversation with you. Worthune gives you the calculators without the build. One script tag your web team can place in an afternoon, backed by math your compliance reviewers can read.
Ship it asunified household management, planning software, or calculators & models. One API under all three.

A script tag and a div
Each calculator is an embed: a script tag and a div. Your marketing site, product pages, or advisor portal can carry them without anyone touching your core stack, and inputs prefill to match the page they sit on.
Math your reviewers can trace
Every calculator publishes its rules: formulas, assumptions, exclusions. IRS, SSA, Medicare, and poverty-guideline figures carry primary-source citations and the date a person checked them. When a reviewer asks where a number came from, there is a link.
A record you can hand over
Any computation also renders as a print-ready report that carries the exact data its record was taken over, so it can be checked years later with nothing but the file. It documents what was computed and says so on its face, rather than claiming to satisfy a recordkeeping rule.
A diligence pack per model
Vendor onboarding usually stalls waiting on documentation nobody has written. Each model renders its own: published rules, test-case summary, constant sources, changelog, and a sample record. How each model is tested before release is written up at worthune.com/methodology.
Current across tax years
When Washington moves a limit we update the sourced registry and the models, version the change publicly, and the tools on your site stay current without a ticket on your roadmap.
Planning tools, plainly labeled
These are illustrative planning models, labeled as such, rather than advice or filing software. Each model's published rules name what it leaves out, which is the part your second line of defense will want to read.
Two deliverables, one computation. Your web team ships the first in an afternoon. The second is what you hand a reviewer or a customer who wants the arithmetic on paper:
| on the page | 2 lines of markup |
| what it renders | a live calculator |
| the same run, printed | POST …/report |
| what the file carries | its own hash payload |
| checkable without a key | yes, at /proof/record |
The embed and the report come off the same engine, so they can’t disagree. The document is checkable from the file alone: it carries the exact data its record was taken over, so anyone holding just the file can recompute it and see that nothing moved. The check needs no key and no account, and nothing of yours is stored on our side to make it work. The report documents a computation rather than certifying compliance, and it prints that distinction on its own face.
One script tag, live today
This is the entire integration. When you are ready for deeper product work, the Growth tier adds unified household management: white-label branding and tenant-bound embeds on your domains, on top of the stored client households every paid plan includes. Custom models built to order are Made-to-measure.

carries its own verification link, and
stays current when tax constants change. -->Questions
Common questions
- What is the easiest way to add financial calculators to a bank website?
- One script tag and a div. Your web team places them wherever a calculator belongs, sets any prefilled values as data attributes, and the calculator renders. There is no build step, no framework requirement, and no back-end integration. The three sample models embed free with an attribution badge, and a subscription covers the full catalog and removes it.
- What will our compliance reviewer ask for?
- Usually three things: what does this compute, where do the numbers come from, and can you show me it was right. Each model has versioned, published rules stating its formulas and what it deliberately leaves out. Every government figure has a registry entry with its primary source and check date. A per-model diligence pack assembles all of it into one print-ready document.
- What happens to the data our customers type in?
- The embedded calculators are stateless. Inputs are not stored, results are not stored, and no personal data is retained. The only thing recorded is an aggregate daily count of which models were called, which contains nothing derived from any individual's inputs.
- How do the calculators stay current with tax and contribution limits?
- Constants come from a versioned registry rather than being written into each calculator, so an update happens in one place with its source recorded. Model behavior changes ship as a version bump with a public changelog entry, never silently, so your compliance file can point at what changed and when.
- Can we run client experiences under our own brand?
- Yes. That is the Growth tier's white-label configuration, and it is the delivery layer of unified household management. You get your brand name, a theme checked for accessibility when it is saved, and your firm's disclosure paragraphs appended to ours. Embeds can then show a real client household, bound to your domain allowlist by short-lived signed tokens. There is also a live reference build you can evaluate and fork, so the client portal starts from working software rather than a blank page.
- Can we customize how the calculators look?
- The embed inherits the surrounding page's typography and can be styled to match your site. The math and the assumptions text stay fixed. That is the part your reviewer signed off on, and letting it be edited per site would make the published rules meaningless.
