c++ Outputs One Too Many Times

I am making a program that outputs an increasing integer until it reaches 400. Even when less than 400 in for "while" is added, it always goes over once. Any Suggestions to fix?

cout << "enter population of US at end of last year (in millions): ";
cin >> USpop;



do {
    USpop = USpop * 1.01007;
    year = year +1;
    cout<< "  " << year  << "  " << setprecision(1) << fixed << USpop <<endl;

} while (USpop < 400);

Maybe like this?

while((USpop *= 1.01007) < 400)
{
    year = year + 1;
    cout << "  " << year << "  " << fixed << USpop << endl;
}
