Loan Eligibility Estimate
Model borrowing capacity from income, existing debt payments, a user-entered ratio, rate, and term.
Borrowing capacity under your assumptions
Estimate a principal amount from income, existing debt payments, your own ratio assumption, rate, and term. This is not approval or preapproval.
Use the before-tax monthly income amount you want to test.
Include the recurring monthly debt payments you want represented in this scenario.
Your scenario input, not a universal lender limit or recommendation.
Divided by 12 for the modeled monthly payment stream.
Must convert to 1 through 600 whole monthly payments.
Calculation assumptions
- *The maximum debt-payment ratio is entered by the user and is not a universal lender rule or recommendation.
- *Available new payment equals income multiplied by the entered ratio, minus existing monthly debt payments.
- *Estimated principal is the present value of that month-end payment stream at the entered nominal annual rate and term.
- *Credit history, verified income, assets, expenses, collateral, fees, taxes, local rules, and lender policy are excluded.

Transparent borrowing-capacity model
The model first calculates a total monthly debt-payment allowance from gross income multiplied by the ratio you enter. Existing monthly debt payments are subtracted to find the maximum modeled new payment.
The estimated principal is the present value of that payment stream: PV = payment x (1 - (1 + r)^-n) / r, where r is the nominal annual rate divided by 12 and n is the number of monthly payments. At a zero rate, principal equals payment multiplied by n.
Verified capacity example
With $10,000 gross monthly income, $1,000 of existing monthly debt payments, and a user-entered 40% ratio, the total modeled debt-payment allowance is $4,000 and the modeled new payment is $3,000.
At a 12% nominal annual rate for 60 months, that payment stream has an estimated present value of about $134,865.12. At 0%, the same payment and term produce $180,000. These are arithmetic scenarios, not lender decisions.
Why this is not loan approval
The CFPB defines debt-to-income ratio as monthly debt payments divided by gross monthly income and notes that limits differ by lender and loan product. Calzivo therefore does not supply a universal threshold.
Real underwriting can consider verified income, assets, other expenses, credit history, collateral, product rules, fees, and lender policy. Calculation methodology is maintained by Calzivo and checked against the sources listed below, but only an actual lender can evaluate an application.
Quick answers
What this calculator answers
- Result: Estimates borrowing capacity from a user-entered payment-ratio assumption and fixed-payment present-value math.
- Method: Subtracts existing debt payments from the modeled total payment allowance, then estimates principal from the remaining payment stream.
- Scope: Educational scenario only. It is not approval, preapproval, affordability advice, or a lender decision.
- Payment check: Use the EMI Calculator to test a specific principal, rate, and term. EMI Calculator

Accuracy and limitations
Calzivo tools are built for practical estimates, conversions, and checks. Some tools use standard formulas or simplified assumptions, and results can be affected by input accuracy, rounding, units, local rules, or changing official requirements.
Finance results are planning estimates, not financial advice. Actual costs or returns can change because of fees, taxes, rates, timing, provider rules, and personal circumstances.

Frequently Asked Questions
Common questions about Loan Eligibility Estimate and how to read the result.
Does this result mean I qualify?
No. It is an educational borrowing-capacity scenario, not approval, preapproval, or a lender decision.
Does Calzivo recommend a debt-payment ratio?
No. The ratio is your input. The CFPB notes that debt-to-income limits differ across lenders and loan products.
What happens when existing debt uses the modeled allowance?
The modeled new payment and borrowing capacity become zero. That describes only the entered scenario and is not a loan rejection.
What does the estimate leave out?
It excludes verified-income rules, assets, living expenses, credit history, collateral, fees, taxes, local requirements, and lender-specific underwriting.
