Our mortgage calculator

The L&C mortgage calculator helps you figure out how much you can borrow for a mortgage based on your income.

Mortgage affordability is judged on many different things, such as your credit history, monthly outgoings and deposit, and can vary from lender to lender. Sometimes taking out a joint mortgage could increase the amount you can borrow, especially if you both have well-paid jobs.

If you’re a first time buyer, then our mortgage calculator can help you get started. These mortgage calculators will give you a good idea of borrowing amounts and costs. If you have any questions, contact one of our expert mortgage advisers to get a complete picture of where you stand and what to do next.

About your borrowing ability

Calculating exactly how much you can borrow depends on a number of things, such as:

  • How much you spend each month on regular commitments
  • Whether you're paid a basic salary, a basic salary plus bonus, commission or overtimeIf you're self employed
  • The amount of deposit you have
  • Your age and whether you are looking to borrow beyond your retirement date

One of the most important factors in determining how much you can borrow is the lender. Each lender has different criteria and as brokers who, last year successfully placed mortgages with 59 different lenders, we are perfectly placed to match the right lender to your borrowing requirements.

What if I need to borrow more?

Sometimes it can be possible to borrow more than the calculator on our website shows you and that's where our expertise comes in. We are sometimes able to arrange higher borrowing by taking your own individual circumstances into account.

* All potential borrowing is subject to affordability checks and credit status

Our mortgage repayment calculator

Our mortgage calculator can show you how much your mortgage repayments will be each month based on the amount you want to borrow, the interest rate, and the number of years you’ll be paying back the mortgage. This means you get a clear idea of your monthly payments and helps you check if your mortgage is affordable.

To calculate your monthly payments, simply adjust these three details in the mortgage calculator:

● The amount you want to borrow
● The interest rate
● The number of years to repay the mortgage

The mortgage calculator will show your likely monthly repayments and the total amount you'll pay over the term. It also shows how much interest you’ll pay

Keep in mind that your interest rate may not stay the same throughout your mortgage term. Most deals only last for a few years. After that, if you don’t remortgage to a new deal, you’ll be moved to your lender’s standard variable rate, which could lead to higher monthly payments.

How much interest will I pay on my mortgage?

The exact amount of interest you’ll pay depends on the mortgage rate you’re on. This can change over time. For example, you might be on a low rate at the moment, but if interest rates rise during this period, you could end up paying a higher interest rate when you come to remortgage, or if you move onto your lender’s standard variable rate.

What is the interest rate change?

If you’ve already got a mortgage, or are about to take one out, you might wonder how interest rate changes could affect your monthly payments. While interest rates are hard to predict, it’s helpful to understand the potential impact any changes might have on your finances.

You can use our mortgage repayment calculator to see how your monthly payments might look with different interest rates by changing the interest rate above.

What does mortgage affordability mean?

Mortgage affordability is the term used when lenders assess whether you can make the monthly repayments on the amount you’re borrowing. They need to take into account multiple factors here - as you can imagine, assessing affordability isn’t a straightforward process.

Lenders will consider things such as your age, job type, how much you earn, and how much you spend every month. They’ll then look at the total amount you’re borrowing to work out whether you can afford to pay it back both at the current rate and if rates were to increase in the future.

Use our mortgage repayment calculator to get a better handle on the payments you’re likely to face, and if you’re wondering “how much mortgage can I afford”? Use our mortgage affordability calculator to get a better idea of how much you’re likely to be able to borrow.

How many times your salary can you borrow for a mortgage?

The amount you can borrow will vary between lenders, but - assuming you pass affordability checks - most lenders allow you to borrow up to between 4.5 and 5.5 times your annual salary. That means that if you earn £30,000, you may be able to get a mortgage of around £150,000. Some lender offer mortgages up to 6 times your salary but this tends to be limited to certain products or professions. Bear in mind that, as well as your salary, lenders will take other factors into account such as your monthly spending, your deposit size, your age, and type of employment.

How are my repayments calculated?

Your mortgage repayments depend on several factors, including how much you’re borrowing, your mortgage term, and the rate of interest you’re paying. If you opt for a repayment mortgage you’ll make monthly repayments which cover both the capital you borrowed and the interest due. If it’s interest only you’ll just be paying the interest rather than reducing the amount you owe. You can find out more about this in our repayment vs interest only guide.

On a repayment mortgage the longer the mortgage term you choose the cheaper your monthly payments will be, but you’ll end up paying back more overall. If you choose a shorter term, your monthly payments might be higher, but you’ll reduce the total amount of interest you need to pay back, as you’ll be paying off the loan more quickly.

 Calculating monthly payments

Once you’ve got an idea of how you’d like to repay your mortgage and how much you can borrow you can get started and calculate your monthly repayments. To work out exactly how much you’ll pay every month, you’ll need to know how much you want to borrow, over how many years, and what interest rate you’ll be paying.

You can then enter these figures into our repayment calculator and it’ll crunch the numbers and tell you how much your repayments might be every month, as well as the total amount you’ll pay over the term. You’ll also see exactly how much interest you’ll pay overall, and when you use our mortgage overpayment calculator, overpayments can also be added to see how this can help bring the total amount you’ll pay down.

Remember that you’re unlikely to pay the same interest rate throughout your mortgage term though, as most deals only last for a few years. If you don’t remortgage to another deal after your initial deal ends, you’ll default to your lender’s standard variable rate which is likely to result in higher monthly payments.

Mortgage calculator FAQs

How much interest will I pay?

The exact amount of interest you’ll pay depends on the mortgage rate you’re on. This can change over time. For example, you might be on a low rate now, but if interest rates rise you could end up paying a higher interest rate when you come to remortgage, or if you move onto your lender’s standard variable rate.

How much will a 100k mortgage cost per month?

The cost of your monthly repayments depends on various factors, including the type of mortgage you’ve taken out, whether you have an interest only or repayment mortgage, how long you’ve borrowed it over and the rate you are on. Typically, your repayments will be lower with an interest only mortgage, as you’re only paying back the interest rather than the total amount borrowed but you will need to factor in the cost of making sure you have enough set aside to repay the mortgage at the end of the term. With a fixed rate mortgage your monthly payments will remain the same for the term of your mortgage, but with a variable rate deal, they may change over time depending on interest rates. The amount you pay back monthly also depends on the length of your mortgage term. If you’ve chosen a 5 year repayment mortgage, your payments will be much higher than a 20 year one, for example.

How is a mortgage calculated?

Mortgage payments have two separate parts: the total amount you’ve borrowed (the capital) and the interest charged on your loan. If you have a repayment mortgage, your monthly payments will cover both of these parts, with a portion of your monthly payment going towards the capital, and the other part covering the interest on your debt. With an interest only mortgage you are only covering the interest with your mortgage payments so the amount you owe is not reducing each month. So in summary your mortgage payments are calculated based on the amount borrowed, the term of your mortgage, the type of mortgage you’ve chosen, and the interest rate. When you take out a mortgage through L&C, we’ll take you through the options and ensure you understand exactly how much you’ll have to pay back every month.

What is mortgage underwriting?

There’s no need to be worried about the mortgage underwriting process - you just need to know what it involves, so you can be prepared for it.

You’ll be asked to provide proof of your income, usually payslips for the last three months, as well as any other income you receive such as benefits, part-time jobs or child maintenance payments.

Getting a mortgage as a self-employed person needn’t be a struggle as long as you can provide proof of your income for the last two full tax years. Typically lenders will ask for 2 years’ accounts or tax returns to demonstrate how much you earn, although some lenders may consider one year’s accounts depending on your situation.

You’ll also need to show your outgoings in the same way as an employed applicant, including things like credit commitments, Council Tax and energy bills. If you’re looking for a self-employed mortgage loan, it’s worth making sure your accounts and tax returns are up to date as soon as possible.

Regardless of your employment status you can also expect your lender to look into your credit history, and any bad credit, late payments or outstanding loans could have an impact on the amount you’re able to borrow.

The process for affordability checks can take anywhere from two to six weeks, but you can minimise delays and ensure that you provide the correct paperwork by applying through a mortgage broker like L&C. We can also help to find the best match for your circumstances, including self-employed mortgage lenders.

How do I increase my chances of getting mortgage approval?

To ensure you have the best possible chance of obtaining mortgage approval, make sure that you check your credit report before starting the mortgage application process. When reviewing your report, which can be done for free via credit reference agencies like Experian, make sure there’s no incorrect information, as any discrepancies could affect your mortgage application.

You should also try and save as big a deposit as possible, but if you are a first time buyer or finding it difficult to save up enough for a big deposit, there are options available to you. You could look at schemes like shared ownership or shared equity, or a guarantor mortgage where a family member agrees to meet your monthly repayments if you can’t. Use our mortgage loan calculator to work out how much you might need to borrow and what deposit you need to save.

To figure out how much deposit you need it’s helpful to know what ‘loan to value’ (LTV) means, so the size of mortgage in relation to the value of the home you want to buy. The lower your LTV, the wider range of mortgages are available to you. Use our LTV calculator to work out your loan to value and find out which mortgages are available to you.

Can you borrow more money than your house costs?

If you’re buying a property that needs renovation, you might be wondering whether you can take out an additional amount on your mortgage to cover the work that needs to be done. Unfortunately, lenders base their mortgage offers on lower of the purchase price or current value of the property. If you have a large deposit you may be able to hold some of that back to carry out the work and borrow more on your mortgage, but generally lenders will not lend more than 90-95% of the current value.

How is mortgage affordability calculated?

All lenders will do an affordability assessment before offering you a mortgage and it’s calculated using a variety of different factors. Firstly, a lender will look at your income - and if you’re buying with someone else, they will also take their income into account, as well as your outgoings to make sure that you can afford the monthly repayments. This includes things like your credit card and loan payments, bills, child care costs, groceries and personal/leisure spending. Lenders also look to understand whether you’ll be able to keep up payments if your mortgage interest rate increases.
