Nettó ↔ bruttó, both ways
Type a net amount and read the gross, or type the gross from a receipt and back-compute the net — one tap flips the direction. Nettó, ÁFA and bruttó are always shown together, and they always add up.
Android app
ÁFA kalkulátor
Nettó ↔ bruttó at the Hungarian VAT rates — with a widget.
A Hungarian-native VAT calculator: 27 / 18 / 5 / 0 % or a custom rate, both directions, the ÁFA-tartalom a receipt prints, forint rounding, one-line copy and share, history and a dated rate guide — with no account and nothing uploaded. Pro removes the ads and adds a home-screen widget.
The Hungarian rates, one row
27 %, 18 %, 5 % and 0 % as chips, plus an egyéni (custom) rate for anything else. The result card also shows the ÁFA-tartalom — 21,26 %, 15,25 %, 4,76 % — the figure printed on Hungarian receipts.
Thinks in forints
A 000 key, thousands grouping, rounding to whole forints by default — or fillér precision when you need two decimals. Copy or share the whole result as one line: „Nettó 10 000 Ft + ÁFA (27%) 2 700 Ft = Bruttó 12 700 Ft”.
History and a rate guide
The last twenty calculations, one tap to bring any of them back. A short, dated guide of what falls under 27, 18, 5 and 0 % — informational, with its sources named, so you can check it against the law.
A widget for Pro
The one-time Pro purchase removes the banner ads and unlocks a home-screen widget: a small calculator with its own keypad and rate chips, so a quick check never needs the app opened at all.
Offline, with no account
No registration, no login, no cloud. What you type, your history and your settings stay on your phone; the app works in airplane mode, and the only network traffic is ads and crash reports.

The four rates
27 % — általános
The general rate, and the highest standard VAT rate in the EU: most goods and services, clothing, electronics, fuel, most food. VAT content 21,26 % — in a 12 700 Ft gross price, 2 700 Ft is VAT.
18 % — kedvezményes
Certain dairy products, goods made from cereals, flour or starch (bread, pasta), and admission to open-air music and dance events. VAT content 15,25 %.
5 % — kedvezményes
Basic foods such as pork, poultry, beef, fish, eggs and fresh milk; medicines; books, e-books and daily papers; restaurant meals; hotel accommodation; internet access; district heating; new homes under conditions. VAT content 4,76 %.
0 % / mentes
Small-business exemption (alanyi adómentesség), where net equals gross; exempt activities such as education, healthcare and parts of financial services; reverse charge; intra-Community supply and export.
A summary, not advice — the app's own guide names its sources and its validity date, and the terms say the same thing in more words.
Why it exists
Generic VAT calculators exist by the dozen, and every one of them makes the Hungarian case a special case: the rate has to be typed, the rounding is to cents, and the number a Hungarian receipt actually prints — the ÁFA-tartalom — is nowhere. This one starts from the Hungarian rates, rounds to whole forints, and speaks the language a freelancer, a bookkeeper or a shop owner already uses: nettó, bruttó, kulcs.
The widget follows from the same idea. Most VAT checks are ten seconds long — a price on a quote, a line on a receipt — and ten seconds is too short to be worth opening an app. So for Pro the calculator lives on the home screen, keypad and all.
Free, with one optional upgrade
The app is free and shows a banner ad served by Google AdMob at the bottom of the screen — never a full-screen one — with a consent prompt where the GDPR requires it. A single one-time purchase, ÁFA kalkulátor Pro, removes the ads permanently and unlocks the home-screen widget. No subscription, no other products. Everything the app does and doesn't collect is spelled out in the Privacy Policy.
Frequently asked questions
What does ÁFA kalkulátor do?
It converts between net and gross amounts at the Hungarian VAT rates — 27 %, 18 %, 5 %, 0 %, or a custom rate — shows the VAT amount and the VAT content, keeps a history, and explains in a short guide which goods and services fall under which rate. It is Hungarian-only by design.
Is it free?
Yes. The app is free and shows a banner ad at the bottom of the screen; there are no full-screen ads. A single one-time purchase, ÁFA kalkulátor Pro, removes the ads and unlocks the home-screen widget. There is no subscription and nothing else for sale.
What is the home-screen widget?
A small VAT calculator that lives on your Android home screen: a keypad, the rate chips and the nettó / ÁFA / bruttó result, usable without opening the app. It follows the app's light or dark theme and its precision setting. It is part of Pro; the free app shows a locked preview.
Does it round to whole forints?
By default, yes — amounts round half-up to whole forints, which is what Hungarian invoices and receipts do. A setting switches to fillér precision (two decimals). Either way the three figures are computed at the precision you see, so nettó + ÁFA always equals bruttó on screen.
Is the rate guide tax advice?
No. The guide is an informational summary with its sources named (the Hungarian VAT Act and NAV) and a validity date, so you can tell how fresh it is. Rates and categories change; for an invoice or a return, the tax authority, the current law or your accountant is authoritative.
Do I need an internet connection?
No. Calculating, the history, the guide and the widget all work offline. A connection is only used to serve ads (in the free version), to send crash reports, and by Google Play for the Pro purchase.
What data does the app collect?
The app itself collects none — no account, no analytics, nothing uploaded. Two things leave your device: crash reports, and the data Google needs to serve ads (with a consent prompt in the EEA). The privacy policy has the full details.
What platforms is it on?
ÁFA kalkulátor is an Android app, available for free on Google Play. Other platforms may follow later.
