Sum of each year's AUM fee after growth
Sum of the fixed annual fee over the horizon
Positive means the AUM model costs more in fees over this period.
After 10 years of growth and AUM fees
After 10 years of growth and flat fees ($139,737 higher than AUM)
Year-1 break-even balance. At 1% AUM and a $3,500 flat fee, the fees match at about $350,000 of portfolio value in year 1. Above that balance, the AUM fee costs more in year 1 dollars. Below it, the flat fee costs more in year 1 dollars.
Estimates only, not advice. Each year the model applies your expected return, then deducts the AUM percentage or the flat annual fee from that post-return balance. It does not model taxes, contributions, or withdrawals. Your actual costs depend on the advisor's fee schedule and what the fee includes.
When a flat fee tends to cost less as balances grow
The calculator is a starting point. These are the decision points most people check after they run their own numbers.
-
Watch the dollar fee as the balance grows
A 1% fee is $5,000 on $500,000 and $25,000 on $2.5 million. A flat fee stays put. If you expect the portfolio to grow, run the calculator at today and at a larger future balance.
-
Compare multi-year totals, not only year 1
Year 1 can look close when the balance is near break-even. Over 10 or 20 years, AUM fees often pull ahead in total dollars paid because they scale with growth. The ending-balance tiles show how that fee drag compounds.
-
Match the fee model to what you need
Fee drag is one input. Also ask what is included: tax planning and filing, equity or crypto complexity, and whether you want a dedicated CPA and CFP on one team. Pricing and the flat-fee CFP and CPA page spell out Nino's scope.
How AUM and flat fees compare
A percentage-of-assets fee scales with your portfolio. A flat fee does not. On smaller balances an AUM fee can be lower in dollars than a flat retainer. As savings grow, the AUM fee in dollars usually rises while a flat fee stays fixed unless you change plans. This page models that fee drag with the same return assumption under both models so you can see total fees paid and ending balances side by side.
