A realistic budget starts with priorities, not spreadsheets. Sit down together and pick the three things that matter most to you, whether that is the food, the photography or the dress.
Next, set aside roughly ten percent as a contingency. Unexpected costs always appear, and having a buffer means they do not become a source of stress.
Track every deposit and due date in one place, and review it monthly. With a clear picture of where your money is going, you can make confident choices and enjoy the planning.
