Free calculators and carefully explained UK money guides. Explore what changes when you adjust the rate, the term or the cost you almost forgot.
Now add a rate, fees and inflation. The answer depends on all three.
A monthly payment is not the same as the full cost. An interest rate is not the same as your after-inflation return. We help you make the missing assumptions visible.
Change the inputs yourself. Every output is an estimate with visible assumptions.
Estimate regular deposits, interest and inflation-adjusted value.

Include the dates and the costs outside the headline payment.
Try a higher cost, lower return or earlier need for the money.
Check access rules, settlement charges and the cash you keep.

Begin with take-home pay, essential bills and irregular expenses. A percentage rule can help you think; your actual direct debits must drive the plan.
Ask when your money arrives, when it needs to leave and which conditions apply to the advertised return.
Our investing tools separate your contributions from hypothetical growth. Markets can fall, fees matter and an ISA is a tax wrapper, not a guarantee.
Test a mortgage payment against a higher rate and the bills that continue after you move in.

Car insurance, servicing, a finance balloon or an early repayment charge can change a decision. Compare written total costs and keep a repair margin.
What must the money do, and when?
Replace examples with your own figures.
Understand the risks outside the formula.
Check live provider information before acting.
