Nothing serious here today
Today is the operative word: we check Financial Calculators every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
build
build_calculator_link
Build a deep link to a SmartMoney77 calculator with pre-filled values that auto-calculate on open. Use list_calculators first to find the slug and its parameters. Example: { "calculator": "bitcoin-history", "lang": "en", "params": { "amount": 1000, "year": 2015 } } → https://smartmoney77.com/en/bitcoin-history?amount=1000&year=2015
build_share_pack
Build everything needed to share a SmartMoney77 calculation on social media in one call: the deep link to the result, a ready-to-embed 1200x628 image URL rendered on our servers, a link that opens the on-site share modal (1200x628, 1080x1080, 1080x1920 downloads), and a localized caption with attribution. Works for all 31 calculators. Example: { "calculator": "fire-number", "lang": "en", "params": { "expenses": 4000, "saving": 1500 } }
calculators
list_calculators
List every SmartMoney77 calculator with its slug, accepted URL parameters and supported languages/currencies. Call this before build_calculator_link. Example: { "group": "history" } returns only the 'what if I had invested' tools.
compare
compare_investments
Run the same "what if I had invested" calculation across 2-8 assets and rank them by final value. USD only, same yearly low/high average pricing as the SmartMoney77 history calculators. Assets: bitcoin, ethereum, solana, sp500, nasdaq100, nvidia, microsoft, meta, apple, tesla, amazon, google, netflix, amd, gold, silver, oil. Example: { "amount": 1000, "buy_year": 2015, "assets": ["bitcoin", "sp500", "gold"] } → each asset's value today, sorted best first, each with its own reproduction link.
compound
compound_interest
Project the future value of an initial amount plus monthly contributions at a given annual return (monthly compounding), and return a link to the same calculation on SmartMoney77. Example: { "initial": 10000, "monthly": 500, "rate": 8, "years": 20 } → futureValue = 343,778. Monthly contributions are made at the end of each month (ordinary annuity).
cost
cost_of_waiting
Compare investing the same monthly amount starting at an early age versus a later age, and show what the delay costs by retirement. Example: { "monthly": 1000, "start": 25, "compare": 35, "retire": 67, "rate": 8 } → a large gap created mostly by compounding, not by the extra contributions.
credit
credit_card_payoff
Calculate how long it takes to clear a credit card balance at a fixed monthly payment and APR, plus the total interest paid. Example: { "balance": 10000, "payment": 400, "rate": 18 } → about 32 months and ~2,600 in interest. Errors when the payment is smaller than the first month's interest.
emergency
emergency_fund
Calculate how many months of expenses current savings cover, the target emergency fund size, the gap, and how long it takes to close it. Example: { "expenses": 3000, "savings": 6000, "contribution": 500, "target": 6 } → 2 months covered, target 18,000, gap 12,000, 24 months to go.
fire
fire_number
Calculate the financial-independence (FIRE) target from monthly expenses using the 4% rule, plus how many years of saving are needed. Example: { "expenses": 4000, "saving": 1500, "current": 50000 } → fireNumber 1,200,000.
historical
historical_investment_return
Compute what a past investment would be worth today (or in a later year), using the same yearly low/high average prices as the SmartMoney77 history calculators. All amounts and prices are in USD only. Assets: bitcoin, ethereum, solana, sp500, nasdaq100, nvidia, microsoft, meta, apple, tesla, amazon, google, netflix, amd, gold, silver, oil. Example: { "asset": "bitcoin", "amount": 1000, "buy_year": 2015 } → units bought, current value, profit, total return and CAGR, plus a link that reproduces it on the site.
inflation
inflation_check
Calculate how much purchasing power cash loses to inflation over time, and what nominal amount keeps the same buying power. Example: { "amount": 100000, "rate": 3, "years": 10 } → realValue ≈ 74,409 and equivalentNeeded ≈ 134,392.
killer
killer_fees
Compare how much a high management fee costs versus a low fee over time on a portfolio with monthly contributions. Example: { "portfolio": 100000, "monthly": 1000, "highFee": 1.5, "lowFee": 0.3, "years": 25 } → the low-fee portfolio ends materially higher.
latte
latte_factor
Calculate what a small recurring daily expense (coffee, cigarettes, takeaway) costs over time and what it would grow to if invested instead. Monthly cost = cost × perWeek × 52 / 12, and monthly contributions are made at the end of each month (ordinary annuity). Example: { "cost": 5, "years": 30, "rate": 8, "perWeek": 5 } → ~108/month spent and a six-figure invested balance.
tool
get_tool_guide
Discovery helper: returns the standard prompt template, argument template, output-interpretation guide and related resources for one or all SmartMoney77 tools, so you can call them correctly without guessing. Example: { "tool": "fire_number" }.

Financial Calculators — questions
Answers built from our own checks of this server.
What can Financial Calculators do?
It exposes 14 tools, read directly from the server on our last check. Among them: build_calculator_link, build_share_pack, compare_investments, compound_interest, cost_of_waiting, credit_card_payoff and 8 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Financial Calculators working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1449 ms. The bar chart above shows every period we have measured.
How do I connect Financial Calculators?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Financial Calculators need an API key?
No. Financial Calculators completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Financial Calculators?
It answers our handshake in 1449 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
