Description
Know your numbers — without the accounting software.
Vickery Finance Calculators adds six practical calculators to any WordPress site. They run entirely in the visitor’s browser, update as you type, and need no accounts, no API keys, and no external services. Every feature is included and unlocked: all six calculators, print/save reports for all of them, and a per-user calculation history.
The six calculators
- Rental Property ROI — monthly cash flow, cap rate, cash-on-cash return, and a Strong / Workable / Thin verdict before you buy.
- Freelance Tax Estimator — self-employment tax, federal income tax, and the quarterly payment, using the 2025 federal brackets and standard deductions, clearly labelled in the interface. Estimate only, not tax advice.
- Break-Even — units and revenue needed to cover costs, contribution margin, and profit at your expected volume.
- Mortgage Payoff — how much extra monthly or lump-sum payments save in interest and time.
- Profit, Margin & Markup — gross and net profit, both margins, and product markup vs. margin (they are not the same thing).
- Savings Goal — the monthly amount needed to reach a goal, or how long a monthly amount takes to get there.
Reports and history, included
Every calculator can print or save a clean report of its inputs and results. Logged-in visitors can also save snapshots of their calculations and review them later with the [vickfica_history] shortcode. Site administrators can review and delete saved entries under VF Calculators History.
Ways to add them
- The “Vickery Finance Calculators” Gutenberg block — pick one calculator or the tabbed six-calculator suite.
- Shortcodes:
[vickfica_calculators]for the suite, or[vickfica_rental],[vickfica_freelance_tax],[vickfica_breakeven],[vickfica_mortgage],[vickfica_profit],[vickfica_savings]individually, plus[vickfica_history]for a logged-in user’s saved calculations.
Privacy
The plugin collects nothing. Calculators run locally in the browser; there is no tracking, no analytics, and no call to any external server. History entries are stored in your own site’s database only when a logged-in user clicks “Save to history”, and they are removed when the plugin is uninstalled.
Blocks

FAQ
-
Which tax year does the Freelance Tax Estimator use?
-
The 2025 tax year. The federal brackets and standard deductions are the 2025 figures, and the calculator says so next to its results. Treat the output as an estimate for planning, not as tax advice.
-
Do the calculators send visitor data anywhere?
-
No. All math runs in the visitor’s browser. There is no tracking, no analytics, and no external request. The only optional write is the calculation history, which stores a snapshot in your own site’s database when a logged-in user explicitly saves one.
-
Is anything locked behind a payment or a key?
-
No. Every calculator, the print/save reports, and the calculation history are fully included and unlocked for every site and every visitor. There is nothing to buy and no key to enter.
-
Can I show a “Calculators by Vickery Finance” credit line?
-
Yes — it is an opt-in setting (VF Calculators Settings) and is off by default, as it should be.
