Boldin alternative: how RetireNumber compares

Formerly NewRetirement. A comprehensive DIY retirement planning platform with a free tier and a paid PlannerPlus subscription.

The short answer

Boldin is the more complete planning platform and has been at this far longer. RetireNumber is cheaper, faster to a first answer and does not ask to connect your accounts. If you want one tool to model every corner of a retirement over years, Boldin is the stronger product. If you want to know whether your number holds up and what would break it, without linking anything, start here.

Where Boldin is the better choice

We would rather you pick the right tool than pick ours.

  • A far deeper feature set built over many more years, including detailed tax modelling and live classes
  • Account aggregation, so balances update themselves instead of being typed in
  • An in-house advisory option if you eventually want a human involved
  • A large, established user base and a long public track record

Where RetireNumber differs

  • No account linking at all, so there is no aggregator holding credentials to your accounts
  • A first answer in about a minute without creating an account
  • Materially cheaper at the paid tier, and a one-time option instead of a subscription
