Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
assets
list_assets
Lists the long-run market rates, which can be used for future plans, and common stocks and funds, which can only be used to look at the past. Stock questions work for any US stock or fund we hold history for, past only. Use it to find a valid long-run rate id.
card
card_event
Records which control was clicked on the calculator card. Used by the card's buttons.
compound
compound_interest
Compound interest calculator with an interactive chart. Works out what a starting amount and monthly deposits grow to at a fixed rate, compounded daily, monthly or yearly, and gives the APY. Use it for savings growth, CD and high-yield savings balances, future value at a fixed rate, and questions like what $10,000 becomes in 10 years at 5%.
crash
crash_impact
Portfolio stress test with an interactive chart. Works out how much a portfolio would lose if stocks fell by a chosen percent, given its mix of stocks, bonds and cash, with an optional loss limit.
dca
dca_vs_lump_sum
Dollar-cost averaging vs lump sum calculator with an interactive chart. Compares investing a fixed amount at each price in a list with investing the same total at the first price, both valued at the last price. Use it when the person provides the price series.
drawdown
drawdown_recovery
Drawdown and loss recovery calculator with an interactive chart. Works out the percentage gain needed to get back to even after a loss, and how many years that takes at a yearly return the person enters.
net
net_worth_check
Net worth calculator with an interactive chart. Subtracts debts from assets and, when an age is given, shows the median net worth for that age group from a US government survey. Use it for a net worth total or a net worth by age comparison.
plan
plan_recurring_investment
Investment growth calculator with an interactive chart. Works out what regular deposits could grow to at a long-run market average or a yearly rate you choose. Use it for monthly investment plans and questions like what $10 a day or $500 a month could become in 20 or 30 years. Single stocks cannot be run forward.
position
position_size
Position size calculator with an interactive chart. Works out the dollar size of one position at a percent cap the person chooses, how many positions of that size fit, and the amount at risk. It does not pick investments or judge whether a size is suitable.
replay
replay_past_investing
Stock return and dollar-cost averaging (DCA) calculator with an interactive chart. Shows what investing in a US stock or fund would have become, using real past prices, as regular deposits, a lump sum, or both. Use it for what-if-I-had-invested and DCA questions about a ticker such as AAPL or VOO, over the last 120 months or fewer. It covers the past only and gives no estimate of the future.
retirement
retirement_plan
Retirement calculator with an interactive chart of the balance by age. Replays a plan through every complete stretch of real US market history since 1928 and reports how often the money lasted. Use it when the monthly spending is known, for questions like can I retire at 60, or how long will my savings last.
safe
safe_spending
Retirement withdrawal calculator with an interactive chart. Finds the highest monthly spending that lasted in at least a chosen share of real US market history since 1928. Use it when the spending amount is the unknown, for retirement income questions, and to check the 4% rule.
sequence
sequence_risk
Sequence of returns calculator with an interactive chart. Runs a list of yearly returns with a fixed yearly withdrawal in the order given and in reverse, and compares where the balance ends.
sp500
sp500_since_date
S&P 500 return calculator with an interactive chart. Shows what a set amount in the S&P 500 would have become between two years from 1928 to 2025, using real yearly returns. It also gives the amount put in after inflation and the worst year in the span.
stocks
search_stocks
Finds US stocks and funds by ticker or company name. Used by the calculator card's stock picker.
tbill
tbill_ladder
Treasury bill ladder calculator with an interactive timeline chart. Lays out how much goes in each same-term bill, how far apart to buy them, and the first and last dates. Shows simple interest only if a rate is given.
