How Rung built the Personal Loan Funded Cost Index

We checked official public sources for 17 personal-loan programs.

We kept advertised terms separate from facts about loans already made. The sample is not the whole market. The examples use stated inputs and do not predict your offer.

This 17-program sample is not the whole market and cannot predict your offer. CC BY 4.0 covers Rung-owned work, with third-party material excluded. This working report is public. Publisher review and third-party source clearance remain pending; no completed reviewer approval is claimed.

A structured sample tests 17 different program models

The unit is one consumer-facing unsecured personal-loan program on the snapshot date. The sample was selected for structural contrast and filing availability. It is not a provider census.

  • No consumer applications, documents, identity, income, or credit data are collected.
  • Secured loans, cards, lines, payday loans, home loans, and business loans are excluded.
  • Brand, platform, creditor, parent, servicer, and funding channel remain separate.

Funded records keep their source population

Class A supports a labeled contextual price comparison. Class B is product-specific but lacks a comparable price measure or cohort. Class C shows scale or structure but mixes products. N means no usable funded evidence was located.

Borrower orientation has a separate category and confidence. It never becomes an eligibility rule.

Only deducted fees use the target-cash formula

fee dollars = loan amount before fees × fee rate
cash after fees = loan amount before fees − deducted fee dollars
loan amount before fees for target cash = target cash ÷ (1 − fee rate)
shelf-to-funded distance = funded APR − aligned shelf floor

Target cash amounts are $5,000, $10,000, and $20,000. Dollar results round to the nearest cent.

Unknown is a result, not a zero

  • A current shelf snapshot may not overlap a funded vintage.
  • Selected pools and active portfolios may not represent all originations.
  • Missing state disclosure does not prove availability or unavailability.
  • A lower-rate consolidation loan does not by itself reduce total debt.
  • Independent calculation, extraction, editorial, rights, and release reviews remain open.
