FinanceVecta
A finance calculator that shows its formulas
In development Android
Time value of money, NPV, IRR, XNPV, XIRR, bond pricing, Black-Scholes options, depreciation, tax estimates and break-even analysis - a full finance calculator that shows its work, on your device. Every result comes with its formula and inputs, so you can check the math instead of trusting a black box. No accounts, no network, no tracking. Informational only - not financial or tax advice.
What it does
Every answer shows its source
Each result carries its formula, inputs and assumptions - reasoning you can review and reproduce, not a bare number.
Private by default
Runs fully offline. No accounts, no ads, no trackers, no network calls. Your figures never leave your device.
Honest about its limits
Informational only - not financial or tax advice. Tax-rule packs are dated editions by region and year, never a silent live source.
Knowledge packs
The catalog as it actually stands. Packs ship to users only after their expert review clears.
- Tax atlas (oep.finance) Planned
Pricing shape
Free
All calculations (TVM, NPV, IRR, bonds, options, tax), the precision label and trace on every result, the amortization schedule, and a current-year tax estimate. On-device, no account, no tracking.
Free means free: no account, no trial clock, nothing expires.
Paid
- Interactive Pro instruments (amortization what-if, sensitivity, option payoff, saved scenarios and export) come with the CoreVecta all-access membership or the one-time CalcVecta Pass that covers every calculator. A standalone FinanceVecta Pro is not sold until those instruments ship.
- Tax-rule packs are one-time, dated editions by jurisdiction and year, verified before open.
Final prices land per market at launch. What you buy keeps working offline, forever.
Questions
Does it work offline?
Yes, entirely. Every calculation runs on your device with no network calls.
Is this financial advice?
No. FinanceVecta is an informational calculator, not financial or tax advice. Verify against your own circumstances and a qualified professional.
The CoreVecta promise
Like every CoreVecta app, FinanceVecta works fully offline, anchors its answers to verifiable sources, and sends nothing anywhere. There is no server to receive it. Knowledge packs state their review status on their face, and packs touching high-stakes domains are reviewed by credentialed professionals before they're labeled ready.
