Crypto calculators for costs
Costs are the one part of investing you control, and these crypto calculators show them in euros before you buy.
Crypto calculators for investing maths
These crypto calculators work through scenarios with prices you choose, so they show the maths without pretending to forecast the market.
Crypto calculators for risk and budget
Before any exchange or coin, these crypto calculators check whether your finances can carry the risk.
Crypto self-tests and checks
Self-tests ask about you rather than about prices, which makes them the most useful tools for many first-time buyers.
Finders and the MiCA licence checker
Finders turn your answers into filters, and the licence checker searches the official register.

A five-step path through the crypto calculators
- Readiness: the financial readiness test checks your buffer, debts and income.

- Budget and share: the investing budget calculator and the stress test set an amount you can afford to lose.
- Exchange: the exchange finder and the licence checker narrow the choice to authorised exchanges.
- Cost and security: the fee calculator and the account security check finish the job.
How the crypto calculators on this site are built
Each calculator uses a standard formula, and the formula is printed on the tool's own page.
Default values are labelled examples and never claim to be any exchange's current price.
No calculator fetches live market data, so you always know which price a result is based on.
- No account, no cookies for tracking, no data sent anywhere.
- Results update as you type.
- Every result can be checked with a pocket calculator.
- Scenarios are labelled as scenarios, not forecasts.
Ideas borrowed from household finance
Several crypto calculators on this site borrow from tools used in household budgeting and loan advice.
| Household finance idea | Crypto version |
|---|---|
| Financial wellbeing check | Financial readiness test |
| Affordability stress test for a loan | Crypto stress test |
| Annual percentage rate of a loan | Annual cost calculator |
| Credit card cost calculator | Card purchase calculator |
| Order of repaying debts | Debt versus invest calculator |
| Monthly budget | Investing budget calculator |
The common thread is simple: the safety of your everyday finances comes before any investment.
What the crypto calculators cannot do
- Predict prices or tell you which coin to buy.
- Calculate tax in your country.
- Replace personal financial advice from a qualified adviser.
They give you numbers to think with, and the decision remains yours.
Crypto calculators for each stage of investing
The crypto calculators on this site follow the order in which decisions are usually made, from "should I" to "how" and "how much".
| Stage | Question | Tool |
|---|---|---|
| Before anything | Can my finances take a large fall? | Financial readiness test |
| Before anything | How would I react to a large fall? | Risk tolerance test |
| Planning | How big should my buffer be? | Emergency fund calculator |
| Planning | Should I repay a loan first? | Debt vs invest calculator |
| Planning | How much per month? | Investing budget calculator |
| Planning | What share of my savings? | Portfolio share calculator |
| Choosing | Which exchange fits me? | Exchange finder |
| Choosing | Is this firm authorised? | MiCA licence checker |
| Buying | What does this purchase cost? | Fee calculator |
| Buying | Is the app's spread expensive? | Spread calculator |
| Holding | What would a crash do? | Crypto stress test |
| Holding | Is my account safe? | Account security check |
| Selling | What is my result after fees? | Profit and loss calculator |
Crypto calculators and the cost of a habit
Costs that look small on one purchase become large over years, and three of the crypto calculators exist to show that effect.
The fee calculator shows the cost of one purchase, the annual cost calculator shows the cost of a trading habit over a year, and the break-even calculator shows how far a price must rise before a trade has paid for itself.
Used together, they answer a simple question: how much of your money goes to the platform rather than into crypto.
Crypto calculators that work with scenarios
Several tools ask you for prices, and that is deliberate: nobody knows future prices, so a calculator that pretended to would mislead you.
- DCA and lump sum: you choose a start, a low and an end price, and see how regular buying and a single purchase compare along that path.
- Staking: you choose a reward rate, a commission and a price change, and see how much the price outweighs the reward.
- Drawdown recovery: you choose a fall and a growth rate, and see the rise and the time needed to recover.
Trying a bad scenario alongside a good one is the most useful habit these tools can teach.
Crypto self-tests: honest answers, private results
The self-tests ask questions that are easy to answer optimistically, so their value depends on honest answers.
Because results stay in your browser and nothing is stored, there is no reason to answer anything other than the truth.
| Self-test | Questions | What a low score means |
|---|---|---|
| Financial readiness test | 8 | Build a buffer and repay expensive debt before investing |
| Risk tolerance test | 7 | Large swings may be hard to live with |
| Investor behaviour quiz | 8 | A low score is good: decisions are plan-driven |
| Problem trading self-check | 10 | A low score is good: few warning signs |
| Scam check | 10 | A low score is good: few red flags |
| Account security check | 10 | Basic protections are missing |
| Crypto knowledge quiz | 10 | Read the guides behind the missed questions |
Crypto calculators for people who already own crypto
If you already hold crypto, start with the tools that look backwards and sideways rather than forwards.
- Check your share: the portfolio share calculator shows whether a rise has pushed crypto above the share you planned.
- Stress-test it: the crypto stress test shows what a fall from today's level would do.
- Check your costs: the annual cost calculator uses your real trading history.
- Check your platform: the MiCA licence checker confirms that your exchange is authorised.
- Check your account: the account security check finds gaps in your settings.
Crypto calculators and privacy
Every calculator and self-test on CoinTrustRadar.com runs as a small script in your own browser.
The numbers and answers you enter are not sent to a server, not stored in cookies and not used for advertising.
The only data the site processes about your visit is your approximate country, used to decide which exchange cards may be shown, as the privacy policy explains.

Crypto calculators: frequently used formulas
All crypto calculators on this site rest on a handful of formulas, which you can also use by hand.
| Question | Formula |
|---|---|
| Cost of one purchase | Amount × (fee + spread) + fixed fees |
| Yearly trading cost | Trades per year × trade size × (fee + spread) |
| Rise needed to break even | 1 ÷ ((1 − buy fee) × (1 − sell fee) × (1 − spread)) − 1 |
| Rise needed after a fall | 1 ÷ (1 − fall) − 1 |
| Net staking rate | Advertised rate × (1 − commission) |
| Crypto share of savings | Crypto ÷ (crypto + other savings) |
| Emergency fund target | Monthly essential expenses × months |
Crypto calculators: examples side by side
Example: one person, three questions, three tools.
- Buffer: expenses of €1,800 a month and a six-month target give an emergency fund of €10,800.
- Budget: after costs, saving and a 5% margin, €210 a month is left for investing.
- Stress test: €6,000 in crypto and €14,000 in other savings means an 80% fall takes 24% of all savings.
Illustrative examples from the tool pages.
Seen together, the three answers show whether the plan holds up, which no single number can.
Crypto calculators on mobile
All tools work on a phone: fields accept decimal input, results update as you type, and nothing needs to be installed.
On small screens, results appear below the fields, so scroll down after entering numbers.
Crypto calculators: common input mistakes
- Entering a percentage as a decimal, such as 0.005 instead of 0.5%.
- Using the maker fee when you will actually use the instant-buy screen.
- Forgetting the spread in broker apps.
- Counting a coin swap as one trade instead of two.
- Using a price from a different exchange than the one you will use.
Crypto calculators: which result matters most?
If you only look at one result from the crypto calculators, make it the effect of a severe fall on your total savings.
Costs, staking rewards and averaging all matter, but none of them changes your life the way losing a large share of your savings can.
The crypto stress test shows that number in under a minute.
After that, the fee calculator and the licence checker help you buy at a fair cost from an authorised firm.
Crypto calculators: limits worth remembering
Crypto calculators simplify reality so that the result is easy to read.
They assume fees stay the same, prices follow the path you enter and nothing unexpected happens in between.
Real markets jump, fees change and life interrupts plans, so treat every result as a guide rather than a promise.
The value of the tools lies in comparing options under the same assumptions, not in predicting what will happen.
Crypto calculators for teachers and parents
The calculators also work as teaching tools, because they show cause and effect with numbers students can change.
- The drawdown recovery calculator shows why losses are harder to recover than they look.
- The annual cost calculator shows how small fees grow with frequent trading.
- The card purchase calculator shows the cost of buying with borrowed money.
- The scam check shows the patterns behind investment fraud.
Crypto calculators: a reminder
None of the crypto calculators on this site recommends buying, selling or holding any crypto-asset; they show numbers so that your own decision is better informed.
