Features

LasagnaFi aggregates every account you connect, then works out what you should do about your taxes, debt, spending, retirement and savings.

Taxes

Upload your tax return and your brokerage forms. LasagnaFi reads them against your connected accounts to find unused contribution room, over-withholding and losses worth harvesting before year end.

  • Unused contribution room in an HSA, 401(k) or IRA
  • Over-withholding against last year's return
  • Unrealized losses that can offset gains
  • Estimated quarterly payments

Debt payoff

Every card, loan and mortgage goes into one payoff schedule. Compare avalanche against snowball, and each one shows you the date you finish paying and the total interest it costs to get there.

  • Avalanche: highest rate first, lowest total interest
  • Snowball: smallest balance first, accounts close sooner
  • Extra monthly payments recalculate the payoff date
  • Mortgages, car loans and cards in one list

Spending

Every transaction is categorized automatically, so you get income, spending and savings rate month by month. Any category running above its own trailing average is flagged and turned into an action with a dollar amount attached.

  • Income, spending and savings rate, month by month
  • Categories compared against their own recent average
  • Flagged categories become actions with a dollar amount
  • Transfers between your own accounts are excluded

Retirement

A Monte Carlo simulation runs your plan through 1,000 market paths out to age 90 and returns a single number: the probability your money lasts. Change your retirement age or your savings rate and all 1,000 run again.

  • 1,000 simulated markets, plus a backtest on real history since 1928
  • On track means an 85% chance or better
  • Change your saving or your retirement age and watch it move

Your financial level

Fourteen steps take you from a starter emergency fund to retirement. LasagnaFi derives which step you are on from your actual balances rather than from a questionnaire.

  • Placed from your balances, recalculated as they change
  • High-rate debt is ordered ahead of investing
  • Each step shows the amount that clears it
  • Steps above your current one stay locked
