Formula Used
The calculator uses the standard monthly mortgage payment formula.
Monthly payment = P × r ÷ [1 − (1 + r)-n]
P is principal. r is monthly interest rate. n is the number of monthly payments.
Modified balance = Current balance + Arrears + Fees − Principal forgiveness
Housing ratio = Total monthly housing payment ÷ Monthly gross income × 100
Monthly savings = Current housing payment − Modified housing payment

Understanding Loan Modification Choices
A loan modification changes the structure of an existing mortgage. It may reduce the rate, extend the term, add arrears, or forgive part of the balance. The goal is usually a payment that fits verified income. This calculator helps you compare a current loan with a proposed modified loan. It does not approve a request. It only organizes numbers for discussion.
Why Payment Ratios Matter
Servicers often review affordability through payment ratios. The housing ratio compares the total housing payment with monthly gross income. Total housing payment can include principal, interest, taxes, insurance, association dues, and escrow. A lower ratio can show stronger affordability. A higher ratio may signal continued stress. The tool lets you set a target ratio, so you can see the payment needed for that goal.
Key Parts Of A Modification
Several inputs can change the result. Capitalized arrears increase the modified balance. Principal forgiveness reduces it. A longer term lowers the monthly amount, but may increase total interest. A lower rate can reduce both payment and interest. Fees also matter because they may be paid upfront or added into the new balance. Testing each part separately helps you understand which change produces the largest relief.
Reading The Results
The result panel shows current payment, modified payment, estimated savings, new balance, payment ratio, and lifetime interest difference. It also shows whether the modified housing payment reaches your chosen target ratio. Use this as a planning view. The final offer may include investor rules, escrow changes, documents, and hardship review.
Practical Planning Tips
Start with accurate statements. Enter the unpaid principal balance, current rate, remaining term, escrow, and arrears. Then test a realistic modified term and rate. Compare several scenarios. Save the CSV for spreadsheet work. Export the PDF summary for a simple record. Before calling your servicer, write down the figures that matter most. Ask how arrears, fees, trial payments, and escrow shortages will be handled. Also ask whether a balloon balance applies. Clear numbers make the conversation easier and reduce confusion.
Keep copies of every notice, trial payment receipt, income document, and hardship letter. If numbers change, rerun the calculator. Small escrow updates can shift affordability and monthly savings by meaningful amounts.
FAQs
Is this an official Mr Cooper calculator?
No. This is an independent planning calculator. It helps estimate possible payment changes before you discuss options with your loan servicer.
What is a loan modification?
A loan modification changes existing loan terms. It may adjust interest rate, term length, unpaid arrears, principal balance, or payment structure.
Does this calculator guarantee approval?
No. Approval depends on servicer rules, investor guidelines, hardship documents, income review, payment history, and program availability.
Why are arrears added to the balance?
Some modifications capitalize missed payments. That means arrears are added to principal instead of being collected separately upfront.
What is the housing ratio?
The housing ratio compares monthly housing payment with gross monthly income. It helps show whether the payment may be affordable.
Why can a longer term increase total interest?
A longer term spreads payments over more months. The monthly payment may fall, but interest can build for a longer period.
What is a deferred balloon balance?
A deferred balloon is an amount not paid monthly. It may become due at payoff, sale, refinance, or maturity.
Should I export the results?
Yes. CSV helps compare scenarios in a spreadsheet. PDF gives a simple summary for your personal records.
