Find how much loan you can afford
Finding how much loan can be afforded starts with the payment that fits the budget. The How Much Loan Can I Afford Calculator takes that payment, annual rate and years, then solves for principal. A $1,500 monthly payment at 6% for 30 years supports roughly $250,000 of loan principal under level amortization.
Lower rates or longer terms raise principal capacity; higher rates shrink it. QuickCalculators shows principal, total interest and payments so cost and capacity appear together.
The same payment on a shorter consumer term supports less principal because fewer periods remain to amortize the balance.
Enter the payment you can manage
Entering the payment you can manage anchors the estimate in cash flow. The How Much Loan Can I Afford Calculator treats payment as fixed and works backward. Derive the payment from surplus after necessities, or from a DTI rule applied separately.
Inflating the payment to chase a larger loan invents capacity that does not exist in the budget. QuickCalculators uses the entered payment without adjusting for taxes or fees.
If payment varies (interest-only phases, HELOCs), use the specialized tools instead of this level-amortization reverse.
See the loan amount and total interest
Seeing the loan amount and total interest completes the reverse calculation. The How Much Loan Can I Afford Calculator reports principal from P = M × ((1+r)^n - 1) / (r(1+r)^n) and then the interest paid over the full schedule.
Two loans with the same payment can have different interest if rate or term differs. Comparing total interest avoids choosing a larger principal solely because the monthly figure fits. QuickCalculators keeps both number of periods and rate visible.
An amortization schedule, when shown, confirms how early payments lean toward interest and later payments toward principal.
Read the disclaimer
QuickCalculators labels loan affordability results as estimates for information only. The How Much Loan Can I Afford Calculator does not provide lending, tax or investment advice. Credit approval and fees sit outside the model.
Correct a common misconception: payment affordability equals loan affordability
A common misconception is that any loan whose payment fits the budget is affordable. Total interest, remaining term risks and asset depreciation still matter. The How Much Loan Can I Afford Calculator reports total interest so payment fit is not the only metric.
Frequently asked questions
How does the How Much Loan Can I Afford Calculator work?
The How Much Loan Can I Afford Calculator reverses amortization: given payment, rate and term, it solves for principal using the standard present-value-of-payments formula.
What payment should be entered?
Enter the monthly payment that fits the budget after other obligations. QuickCalculators does not invent a payment from income on this page.
How do rate and term affect the loan amount?
Lower rates and longer terms increase the loan amount supported by the same payment. Higher rates and shorter terms decrease it. The How Much Loan Can I Afford Calculator recalculates principal when either changes.
Is this the same as the house affordability calculator?
No. The house tool estimates payment from income and DTI first. This tool takes payment as a direct input and is the general reverse-loan case.
Summarize the How Much Loan Can I Afford Calculator
The How Much Loan Can I Afford Calculator converts an affordable monthly payment, rate and term into a loan principal and total interest. QuickCalculators uses reverse amortization and labels results as estimates, not advice.
