What Is the Borrowing Power?
Borrowing power is the amount a lender is willing to let you borrow, based on your income, your existing debts, your day-to-day living expenses, and the loan terms you’re working with. It’s a slightly different question than “how much house can I afford,” though the two are closely related — borrowing power looks specifically at the loan amount itself, while affordability also factors in the resulting home price and monthly comfort level.
This is done by lenders through debt-to-income (DTI) ratios, which set the maximum amount of your monthly gross income that can be allocated to paying off debts, including the new debt for which you are seeking the loan. Some lenders further use another ratio known as the housing expense ratio, which sets the maximum amount of your income that can be devoted to housing expenses, including principal, interest, taxes, insurance, and association dues. Moreover, most lenders (as well as good borrowers) verify that you have some cushion left over.
How Do I Calculate My Borrowing Power?
This is one method of calculating the front-end capacity yourself. You start with these steps:
Step 1: Calculate Your Total Monthly Income
Add your primary income, partner or co-borrower income, and other monthly income after converting them to a monthly figure first if their income is paid weekly, bi-weekly, semi-monthly, quarterly, or yearly.
Step 2: Apply Your Maximum Debt-to-Income Limit
Back-End Capacity = (Monthly Income × Maximum DTI %) − Existing Monthly Debt
This tells you the most you could put toward a new loan payment while staying under your target total DTI ratio, commonly somewhere around 36% to 43% depending on the lender.
Step 3: Apply a Housing Ratio Limit (If Used)
Housing Capacity = Monthly Income × Maximum Housing Ratio %
In some cases, a lender will put a cap on just the housing portion of the expense ratio, independent of the debt portion. For such cases, choose the smaller value between this amount and the back-end capacity calculated in Step 2.
Step 4: Compare Your Living Expenses
Residual Capacity = Monthly Income – Current Debt – Living Expenses
Even if a lender does not require this step in the calculation of your front-end capacity, it is wise to perform it because it will give you an idea of your maximum affordability of a loan, taking into account all living expenses including rent, utilities, groceries, and insurance.
Step 5: Subtract Your Housing Expenses and Then Calculate Your Loan
Now that you have considered whether you will be including real estate tax, insurance, or Home Owners Association fees, then subtract this from the total housing budget and use the result along with the interest rate and term of the loan in the equation to calculate the loan amount.
Step 6: Add the Down Payment
Maximum Property Price = Loan Amount + Down Payment
This is the maximum property price that you can afford. This is easy to do manually for one instance, but if you need to calculate several instances of interest rate, terms, or debts, this will become tedious – this is where the calculator comes in handy.
How to Use the TankCalculator’s Borrowing Power Calculator
1. Choose your currency and income frequency, then enter your primary income, plus any partner or other regular income.
2. Input your current monthly debt obligations such as credit cards, car payments, student loans, personal loans and others.
3. Add your monthly expenses in one figure or, if you choose “use detailed expense breakdown,” distribute them between household, utilities, food, transportation, insurance, childcare and other expense categories.
4. Select your interest rate, loan length, down payment, payment interval and loan type (principal and interest or interest only).
5. If applicable, select “include property tax / insurance / HOA” and enter your monthly payments to incorporate them into your housing budget.
6. Tweak your maximum debt-to-income ratio and use a different housing ratio limit if required by your lender.
7. Click the “Calculate Button”: This will provide you with an immediate answer after you click it.
Use the sensitivity table to see how changing one variable — rate, term, income, debt, expenses, or down payment — moves your borrowing power, or switch to the Compare Scenarios tab to run two assumption sets side by side.

About the TankCalculator’s Borrowing Power Calculator
Our Borrowing Power Calculator automates the debt-to-income process described above, and goes a step further by letting you weigh multiple scenarios against each other. You enter your income, debts, living expenses, and loan assumptions, and it works backward to estimate the loan amount and property price you could reasonably qualify for.
It manages income and debts through eight currencies (US Dollar, Euro, British Pound, Indian Rupee, Canadian Dollar, Australian Dollar, UAE Dirham, and Japanese Yen) and six income frequencies, thus making sure that all the amounts get standardized to a month automatically regardless of how you get your money. Your living costs may either be put down as an overall sum or broken down into details such as household expenses, utilities, food, etc.
On the lending side, it supports principal-and-interest or interest-only loans, adjustable loan terms, and optional inclusion of property tax, insurance, and HOA costs. You can also set your own maximum debt-to-income ratio and, if you want a stricter check, apply a separate housing expense ratio limit. A built-in sensitivity table shows how your borrowing power shifts as you vary the interest rate, term, income, existing debt, expenses, or down payment, and a side-by-side scenario comparison tab lets you test two full sets of assumptions against each other at once.

Benefits of Using the TankCalculator’s Borrowing Power Calculator
The real value here is being able to see your numbers from more than one angle without redoing the math each time — instead of running the loan formula by hand for every rate or debt scenario you’re curious about, you can adjust a field and watch the borrowing power, DTI ratios, and loan-to-value update instantly. That’s really useful if you’re a new buyer who wants to figure out what you’d be eligible for before going to talk to the lender, or if you’re figuring out which one will affect your ability to borrow more: putting money towards paying off the credit card or saving up for a bigger down payment. It’s really clear to see what the differences will be from the sensitivity table and scenarios: what kind of value a lower interest rate makes, or how it will affect your loan-to-value ratio if you save up for a bigger down payment. But since it takes into account both your expenses and leftover income, it can tell you how much you can afford to borrow in a practical sense, too.
