Equation Preview

Blended rate = weighted average: \( r_b=\dfrac{\sum A_i r_i}{\sum A_i} \), where \(A_i\) are balances, \(r_i\) are rates (decimals). :contentReference[oaicite:1]{index=1}
Use this for combined loan, mortgage, or debt APR snapshots; it’s common on mortgage “blend” tools. :contentReference[oaicite:2]{index=2}
Leave any unused row blank; only rows with both amount and rate are included.
You can type expressions like 1.5e4 or 12000+500 — they’ll be parsed safely.
