Why Savings Plan Logic Doesn't Work for Loans

The new auto-invest system feels like a step backward, and I think it's worth explaining why.

The core issue is a product-market fit mismatch: savings plans make sense for equities, where you deploy capital once and let it compound. Loans are fundamentally different — they amortize. Principal and interest return continuously, so reinvestment isn't a one-time event but an ongoing operational requirement. Applying a brokerage-style savings plan to a loan portfolio creates structural cash drag by design.

The weekly reinvestment interval is the most obvious symptom, and the logic is simple: the plan deploys a fixed amount on a fixed schedule, nothing more. So any cash returned between cycles sits uninvested. The more productive your portfolio — the more interest and principal coming back — the larger that idle surplus grows. You're essentially penalized for having a well-performing portfolio.

With the old priority-based system, idle funds were reallocated automatically and continuously. That matched how loans actually behave.

For the record, the old system had real shortcomings too: the hard portfolio size cap was arbitrary (why not allow an uncapped allocation?), and the inability to route interest payments directly to a linked bank account was a meaningful quality-of-life gap. Both are worth fixing.

But the solution shouldn't be to replace a system built around the mechanics of lending with one borrowed from equity investing. I'd strongly encourage Mintos to reconsider — either restore the priority-based logic or build something that actually accounts for the continuous cash flow nature of loan portfolios.

  I completely agree. Incidentally, all the changes over the past year have been solely in Mintos’s interest, not that of their clients. For example, the monitoring of late payments has been removed, and the investment per portfolio is also nonsensical for the investor (see my latest monthly update). 
  The problem of cash drag is almost impossible to solve. Mintos also has no means of ensuring lenders make repayments.
  To be most efficient when reinvesting the daily cash flow that comes back, the best approach is to invest everything yourself (and also sell at the right time). That takes a lot of time, but anyone who lets the algorithms do it misses out on a lot of potential.

  I wanted to say thanks to Mintos for rolling out the daily investment option with no minimum amount. It mostly solved my issue I posted above.

  One quick suggestion: Could we get a way to opt out of the automated emails for these plans? I find the notifications about successful (or failed) executions a bit redundant, especially when the balance is low and I’m already aware of the account status.

  Having a toggle to silence those alerts would be a quality-of-life improvement, especially to avoid daily/weekly/... emails cluttering the inbox.

  Thanks

  Thanks for taking the time to share this feedback, and great to hear that the daily investment option is already helping with your use case.

  I’ve passed your suggestion on to the relevant team. We agree that having more control over notification preferences (including the ability to opt out of these automated execution emails) would meaningfully improve the experience, especially for investors who prefer a cleaner inbox or already monitor their account regularly.

  This is something we’ll look into introducing so you can choose which types of emails you want to receive, and better tailor notifications to your needs.
