Think of it as a shortcut to clarity. Instead of scribbling figures on a notepad or fiddling with spreadsheets, try using a mortgage calculator which will give you a quick and easy breakdown of your estimated monthly repayments.
Whether you’re just starting your property journey or reviewing your current deal, it’s a smart way to understand what you can realistically afford and how different options could impact your finances.
Every mortgage is made up of a few moving parts:
Mortgage calculators use this information to give you a monthly figure—helping you budget better and explore deals that suit your goals.
Keep in mind: your actual deal will depend on factors like your income, credit history, outgoings, and deposit size. But a mortgage calculator is a great starting point to explore what’s possible.
When choosing a mortgage, one size doesn’t fit all. Here’s a quick breakdown of some common options:
Your monthly payments stay the same for a set period (usually 2–5 years, sometimes longer). It’s ideal if you want certainty and to protect against interest rate rises.
Your payments can go up or down, depending on changes to your lender’s standard variable rate or the Bank of England base rate. Great when rates are low—but riskier if they rise.
These track your lender’s SVR, but with a discount applied for a set time. You’ll benefit from lower initial payments—but only while the discount lasts.
You only pay the interest each month, not the loan itself. Monthly costs are lower, but you’ll need a plan to repay the full amount at the end of the term.
Switching deals—either with your current lender or a new one—can help you reduce your interest rate, release equity, or get better terms
For most buyers, a deposit is essential. While 100% mortgages do exist, they’re rare and usually involve a guarantor. Most lenders will expect at least 5–10% of the property’s value upfront.
If you’re aiming to buy soon, start putting money aside now. Set up a direct debit into a savings account and look for small lifestyle changes—like cutting back on unused subscriptions or finding cheaper rent—to accelerate your savings. Every little helps when it comes to getting on the ladder.
The mortgage calculator is an invaluable tool that provides you with an estimate of how much you could borrow from a bank or lender and importantly, what your monthly repayments and other costs might be, for a mortgage.
Active Mortgages have been helping the self-employed, business owners, freelancers, and those with more “normal” working circumstances, find their way around the mortgage market. Our mortgage calculator is no different, it can help you estimate based on your “normal” monthly income levels. So whether you are a first time buyer, or if you are looking to remortgage, move or buy an additional home, or you’re a buy-to-let landlord, our mortgage calculator can help.
To use the mortgage calculator, you need to know a bit about your income and your current debts, so have a payslip or monthly accounts to hand as well as recent records of any credit cards, store cards, loans, overdrafts, and pensions and any other debt you may have.
You will need to know how many people are applying for the mortgage as this of course makes a difference, same goes for a remortgage, second mortgage, buy-to-let etc.
Our calculators give you an idea of what you might be able to borrow from us to buy a home, and what your monthly and total mortgage payments could be, for different types of mortgages. Unfortunately, lenders will undertake a number of checks and many factors may make it more difficult for you to secure a great mortgage deal.
At Active Mortgages, we believe in making the mortgage process feel simple, not stressful. Try using a mortgage calculator for an instant snapshot of your potential costs—so you can plan with confidence. Once you’ve got your figures, we’re here to help you move forward. Whether you’re comparing lenders, unsure of your next step, or just want some expert guidance, our team is just a phone call away.
