Under Fannie Mae Servicing Guide F-1-05 & CFPB TILA Reg Z, applying a $150,000 lump-sum principal recast to a $550,000 mortgage at 6.5% with Rocket Mortgage, LLC reduces your required monthly P&I payment by $970.53/mo (from $3,558.59 to $2,588.06) and saves $176,098.08 in lifetime interest using M = P[r(1+r)^n]/[(1+r)^n-1] over 336 remaining months.
How much does a $150,000 mortgage recast lower my monthly payment on a $550,000 loan at 6.5%?
Applying a $150,000 principal curtailment and formal re-amortization on a $550,000 balance at 6.5% over 336 remaining months lowers your required monthly P&I payment by $970.53/mo (dropping from $3,558.59 to $2,588.06) while saving $176,098.08 in cumulative interest.
What is the Rocket Mortgage, LLC mortgage recast fee and minimum lump-sum requirement?
Under Fannie Mae Servicing Guide F-1-05, Rocket Mortgage, LLC charges a $250 administrative recast fee with no credit check, no home appraisal, and no change to your 6.5% interest rate. Minimum lump-sum thresholds range from $5,000 (Chase, Bank of America, PennyMac, Citibank) to $10,000 or 10% UPB (Wells Fargo, Rocket Mortgage, Mr. Cooper, U.S. Bank).
Is it better to recast a mortgage or make extra principal payments without recasting?
Extra principal payments alone shorten your payoff date but leave your required monthly obligation unchanged at $3,558.59. A formal mortgage recast re-indexes the remaining principal (400,000 USD) across your remaining 336-month term, legally reducing your mandatory monthly payment to $2,588.06.

Don't Just Pay Extra Online: Lock In Your -$1,282.20/mo Lower Monthly Payment ($175,848 Total Interest Saved)
1. Avoid the Online Payment Mistake: Sending $150,000 through Rocket Mortgage's regular 'Extra Principal' button will NOT lower next month's required bill unless you open an official Recast Request first. 2. Lender Minimum Check: ELIGIBLE (Rocket Mortgage $10,000 Minimum Met • $250 Fee). 3. Early PMI Removal & Daily Interest Cost: Your lump sum brings your loan-to-value from 85.0% to 61.8% (20%+ equity), which lets you cancel monthly PMI at the same time for an extra +$311.67/mo in savings ($1,282.20/mo total relief). Every day your cash sits waiting costs about $26.71/day ($801.30/mo) in mortgage interest.
