Less is Mortgage is a free mortgage comparison tool that helps you compare different mortgage scenario cashflows side-by-side (e.g. fixed vs tracker rates, different length terms, and total costs). Make informed decisions about your mortgage.
If Plan A is cheaper, the line goes up, and if Plan B is cheaper, the line goes down.
If Plan A is cheaper, the bar goes up, and if Plan B is cheaper, the bar goes down.
Principal repaid is shown as a positive number, and interest paid is shown as a negative number (being higher 'up' the graph is good)

What percentage of the monthly payment is used to repay the principal.
Less is Mortgage lets you compare two mortgage scenarios side by side. Set up Plan A and Plan B with different rates, terms, and product fees, and instantly see charts showing how the costs compare over time.
Tracker mortgages use Bank of England base rate forecasts from ING, so you can see how future rate changes might affect your payments. You can also adjust the forecast with your own opinion — making rate changes bigger or smaller, earlier or later.
This is the question most UK mortgage holders face at renewal. A fixed rate gives certainty — you know exactly what you'll pay each month. A tracker can be cheaper if rates fall, but more expensive if they rise.
The answer depends on your circumstances: how long you plan to stay, whether you can absorb payment increases, and what you think rates will do. This calculator helps you see the numbers for your specific situation rather than relying on generalisations.
A shorter fix typically has a lower rate but you remortgage sooner, paying arrangement fees again and taking on rate risk earlier. A longer fix costs more per month but locks in your rate for longer.
Use the calculator to compare the total cost of each option over the same period. Set Plan A to a 2-year fix and Plan B to a 5-year fix with your actual quoted rates to see which works out cheaper overall.
No. This is a maths tool that shows you how different mortgage scenarios compare. It is not regulated financial advice. Always speak to a qualified mortgage adviser before making decisions.
The calculations are simplified — interest is calculated monthly rather than daily, and base rate changes are rounded to the nearest month. The results are useful for comparing scenarios against each other, but won't match your lender's exact figures.
The default forecasts come from ING's published base rate predictions. You can adjust these using the Base Rate Opinion controls to see how different rate paths would affect your costs.
