Strategy

By default, invio splits what you save each month: the employer match first, then expensive debt, then tax-advantaged accounts before taxable ones. IRS limits are built in, and Pro lets you set your own order.

Trades to Get Back to Your Target

Rebalancing · Pro

invio compares your holdings with the target mix you set and lists the trades that close the gap. By default it leaves taxable accounts alone, so rebalancing doesn't trigger capital gains tax.

Questions.

What is invio?

An investment and retirement planner for do-it-yourself investors.+

You enter your accounts, debts, and goals once. invio works out an order for each month's savings, when you can reach financial independence, how your plan would have done in past markets, and how each way of drawing your money down in retirement plays out.

Is invio financial advice?

No. It's a planning tool, and the decisions are yours.+

invio isn't an advisor and knows only what you enter. It runs the numbers on your accounts, your goals, and the settings you choose, and shows what each option leads to. Presets such as tax rules, return assumptions, and allocation mixes give you a starting point; they're offered as they are, so check them and change what doesn't fit. invio earns only from subscriptions: no commissions, no fund fees, no paid placements.

Who is invio built for?

U.S. investors who plan on their own.+

People in the U.S. who invest on their own through a 401(k), IRA, HSA, or taxable account and want a long-term plan. invio offers preset tax and account rules that follow U.S. law: starting points to check and change, with no guarantee they fit you.

What makes invio different?

It answers planning questions with your own numbers.+

Budgeting apps track what you spend. invio starts from your accounts and answers the bigger questions: where the next dollar goes, when you can stop working, and how to withdraw in retirement. You can test each plan against market history since 1928.

Why no bank or broker linking?

Privacy, and fewer things that break.+

Bank connections run through outside companies that hold access to your accounts and break when a bank changes its website. invio skips them. You update balances yourself.

How much effort does this take?

A one-time setup, then a few minutes per update.+

Setup means entering your accounts, debts, and goals once. After that, you update balances when you want, for example once a quarter.

Can I start for free?

Yes, and no card is required.+

Yes. The free plan includes your net worth, savings order, forecast, and four history snapshots. Pro adds the rest.
