What is published here
MyCalcVault publishes browser-based calculators, decision worksheets, and supporting explanations for four connected areas: home buying, vehicle financing, savings goals, and long-term investment projections. Calculator inputs stay in the browser; the site does not require an account to produce a result.
| Area | Published tools | What the tools are built to compare |
|---|---|---|
| Home buying | Mortgage, affordability, cash-to-close, and rent-versus-buy worksheets | Financing, all-in monthly cost, transaction cash, household cash flow, and stay-horizon scenarios. |
| Vehicle financing | Itemized auto-loan calculator | Trade equity, payoff, tax, fees, rebates, term, APR, and extra-principal scenarios. |
| Savings | Goal-based savings calculator | APY, contribution timing, goal date, required monthly deposit, and yearly milestones. |
| Investing | Investment scenario calculator | Gross return, annual fee, inflation, contribution growth, and lower/base/higher return cases. |
Who owns and builds MyCalcVault
Bojan Marinkovic is the named owner, digital publisher, calculator builder, author, and tester. His professional occupation is Production Technician. He does not present that occupation as a finance qualification; the author profile states his background and limits directly.
Bojan is the single named person accountable for implementation choices, explanatory copy, source selection, release checks, and correction decisions.
What happens before a calculator change is published
| Stage | Concrete check | Public evidence |
|---|---|---|
| Define | State the input convention, calculation order, exclusions, and display rounding before presenting a result. | The methodology specification lists each model. |
| Test | Run known-answer cases, zero-rate boundaries, invalid-input checks, and default page cases. | Expected inputs and outputs are published in the methodology test table. |
| Publish | Keep the visible explanation, result labels, tables, downloadable schedules, and source notes consistent with the implemented model. | Each calculator shows its assumptions next to the tool. |
| Correct | Reproduce a reported problem from the submitted URL, inputs, expected result, and observed result. | A substantive correction changes that page's own date and, when relevant, its test case. |
Primary-source and geographic boundaries
Amounts are shown in U.S. dollars and the supporting material is written primarily for U.S. terminology. Mortgage fields are checked against the structure described in the CFPB Loan Estimate explainer; auto-finance comparisons use the CFPB auto-loan comparison guidance; APY terminology follows the CFPB Regulation DD definition; and investment-growth context links directly to Investor.gov.
Those sources support terminology and disclosure context. They do not certify MyCalcVault, and a simplified calculator does not automatically adapt taxes, insurance rules, lending practices, deposit protections, or legal requirements for every state or country.
What the site does not claim to be
MyCalcVault is not a bank, lender, broker, accounting firm, law firm, or licensed advisory practice. The content is educational and general. It is not individualized financial, investment, legal, or tax advice.
Readers should verify important decisions with the relevant provider or a qualified professional when the stakes are high or the situation is unusually specific.
Correction responsibility
Send a possible calculation, wording, source, accessibility, or broken-link problem to contact@mycalcvault.com. For a calculator, include the page URL, every input, the result shown, and the result you expected. That information makes the issue reproducible instead of subjective.
Page dates are changed only when the affected page receives substantive work. A template deployment or unrelated site change does not justify changing every date at once.
